124-417: Walkman ( Japanese : ウォークマン , Hepburn : U~ōkuman ) is a brand of portable audio players manufactured and marketed by Japanese company Sony since 1979. The original Walkman started out as a portable cassette player and the brand was later extended to serve most of Sony's portable audio devices; since 2011 it consists exclusively of digital flash memory players. The current flagship product as of 2022
248-490: A Dolby calibration control is included. For recording, a reference tone at Dolby Level may be recorded for accurate playback level calibration on another transport. At playback, the same recorded tone should produce the identical output, as indicated by a Dolby logo marking at approximately +3 VU on the VU meter(s). In consumer equipment, Dolby Level is defined as 200 nWb/m , and calibration tapes were available to assist with
372-409: A Dolby B "pass-through" mode. In 1971 WFMT started to transmit programs with Dolby NR, and soon some 17 stations broadcast with noise reduction, but by 1974 it was already on the decline. Dolby FM was based on Dolby B, but used a modified 25 μs pre-emphasis time constant and a frequency-selective companding arrangement to reduce noise. A similar system named High Com FM
496-657: A Walkman in bags or pockets. In October 1985, the WM-101 model was the first in its class with a "gum stick" rechargeable battery. In 1986 Sony presented the first model outfitted with remote control, as well as one with solar battery (WM-F107). Within a decade of launch, Sony held a 50% market share in the United States and 46% in Japan. Two limited edition 10th anniversary models were released in 1989 (WM-701S/T) in Japan, made of brass and plated in sterling silver . Only
620-637: A benefit from the in-group to the out-group) means "[I/we] explained [it] to [him/her/them]". Such beneficiary auxiliary verbs thus serve a function comparable to that of pronouns and prepositions in Indo-European languages to indicate the actor and the recipient of an action. Japanese "pronouns" also function differently from most modern Indo-European pronouns (and more like nouns) in that they can take modifiers as any other noun may. For instance, one does not say in English: The amazed he ran down
744-402: A complex series of filters that change according to the input signal. As a result, Dolby SR is much more expensive to implement than Dolby B or C, but Dolby SR is capable of providing up to 25 dB of noise reduction in the high-frequency range. It is only found on professional recording equipment. In the motion picture industry, as far as it concerns distribution prints of movies,
868-414: A distinct language of its own that has absorbed various aspects from neighboring languages. Japanese has five vowels, and vowel length is phonemic, with each having both a short and a long version. Elongated vowels are usually denoted with a line over the vowel (a macron ) in rōmaji , a repeated vowel character in hiragana , or a chōonpu succeeding the vowel in katakana . /u/ ( listen )
992-480: A few hundred were built of each. A 15th anniversary model was also made on July 1, 1994, with vertical loading, and a 20th anniversary on July 1, 1999, with a prestige model. By 1989, 10 years after the launch of the first model, over 100 million Walkmans had been sold worldwide. 150 million units were manufactured by 1995. By 1999, 20 years after the introduction of the first model, Sony sold 186 million cassette Walkmans. Portable compact disc players led to
1116-419: A glide /j/ and either the first part of a geminate consonant ( っ / ッ , represented as Q) or a moraic nasal in the coda ( ん / ン , represented as N). The nasal is sensitive to its phonetic environment and assimilates to the following phoneme, with pronunciations including [ɴ, m, n, ɲ, ŋ, ɰ̃] . Onset-glide clusters only occur at the start of syllables but clusters across syllables are allowed as long as
1240-415: A high-frequency signal, known as bias, is mixed in with the recorded signal, which "pushes" the envelope of the signal into the linear region. If the audio signal contains strong high-frequency content (in particular from percussion instruments such as hi-hat cymbals ), this adds to the constant bias causing magnetic saturation on the tape. Dynamic, or adaptive, biasing automatically reduces the bias signal in
1364-585: A high-level stage and a low-level stage) staggered action arrangement of series-connected compressors and expanders, with an extension to lower frequencies than with Dolby B. As in Dolby ;B, a "sliding band" technique (operating frequency varies with signal level) helps to suppress undesirable breathing , which is often a problem with other noise reduction techniques. As a result of the extra signal processing, Dolby C-type recordings will sound distorted when played back on equipment that does not have

#17327581768501488-484: A listener depending on the listener's relative social position and the degree of familiarity between the speaker and the listener. When used in different social relationships, the same word may have positive (intimate or respectful) or negative (distant or disrespectful) connotations. Japanese often use titles of the person referred to where pronouns would be used in English. For example, when speaking to one's teacher, it
1612-418: A maximum volume they can record, so already-loud sounds will become distorted. The idea is to increase the volume of the recording only when the original material is not already loud, and then reduce the volume by the same amount on playback so that the signal returns to the original volume levels. When the volume is reduced on playback, the noise level is reduced by the same amount. This basic concept, increasing
1736-446: A person as they were walking. In the 1970s, Brazilian inventor Andreas Pavel devised a method for carrying a player of this type on a belt around the waist, listening via headphones , but his " Stereobelt " concept did not include the required engineering advancements to yield high-quality sound reproduction while the tape player was subject to mechanical shock as would be expected on a person walking. Pavel later lost his suit claiming
1860-452: A priority period of several years for use in consumer products, to protect their own Beocord 9000 cassette tape deck. By the middle of the 1980s the Bang & Olufsen system, marketed through Dolby Laboratories, became an industry standard under the name of Dolby HX Pro. HX-Pro only applies during the recording process. The improved signal-to-noise ratio is available no matter which tape deck
1984-419: A relatively noisy tape size and speed. It is common on high-fidelity stereo tape players and recorders to the present day, although Dolby has as of 2016 ceased licensing the technology for new cassette decks. Of the noise reduction systems, Dolby A and Dolby SR were developed for professional use. Dolby B , C , and S were designed for the consumer market. Aside from Dolby HX , all
2108-408: A sentence need not be stated and pronouns may be omitted if they can be inferred from context. In the example above, hana ga nagai would mean "[their] noses are long", while nagai by itself would mean "[they] are long." A single verb can be a complete sentence: Yatta! ( やった! ) "[I / we / they / etc] did [it]!". In addition, since adjectives can form the predicate in a Japanese sentence (below),
2232-428: A single adjective can be a complete sentence: Urayamashii! ( 羨ましい! ) "[I'm] jealous [about it]!". While the language has some words that are typically translated as pronouns, these are not used as frequently as pronouns in some Indo-European languages, and function differently. In some cases, Japanese relies on special verb forms and auxiliary verbs to indicate the direction of benefit of an action: "down" to indicate
2356-425: A wider tape. Cassette tapes were originally designed to trade off fidelity for the convenience of recording voice by using a very narrow tape running at a very slow speed of 1 + 7 ⁄ 8 in/s (4.8 cm/s) housed in a simple plastic shell when 15 in/s (38 cm/s) or 7 + 1 ⁄ 2 in/s (19 cm/s) tape speeds were for high fidelity, and 3 + 3 ⁄ 4 in/s (9.5 cm/s)
2480-680: Is compressed rather than protruded , or simply unrounded. Some Japanese consonants have several allophones , which may give the impression of a larger inventory of sounds. However, some of these allophones have since become phonemic. For example, in the Japanese language up to and including the first half of the 20th century, the phonemic sequence /ti/ was palatalized and realized phonetically as [tɕi] , approximately chi ( listen ) ; however, now [ti] and [tɕi] are distinct, as evidenced by words like tī [tiː] "Western-style tea" and chii [tɕii] "social status". The "r" of
2604-421: Is topic–comment . Sentence-final particles are used to add emotional or emphatic impact, or form questions. Nouns have no grammatical number or gender , and there are no articles . Verbs are conjugated , primarily for tense and voice , but not person . Japanese adjectives are also conjugated. Japanese has a complex system of honorifics , with verb forms and vocabulary to indicate the relative status of

Late Middle Japanese has the first loanwords from European languages – now-common words borrowed into Japanese in this period include pan ("bread") and tabako ("tobacco", now "cigarette"), both from Portuguese . Modern Japanese is considered to begin with the Edo period (which spanned from 1603 to 1867). Since Old Japanese,
2852-527: Is also used in a limited fashion (such as for imported acronyms) in Japanese writing. The numeral system uses mostly Arabic numerals , but also traditional Chinese numerals . Proto-Japonic , the common ancestor of the Japanese and Ryukyuan languages , is thought to have been brought to Japan by settlers coming from the Korean peninsula sometime in the early- to mid-4th century BC (the Yayoi period ), replacing
2976-440: Is appropriate to use sensei ( 先生 , "teacher"), but inappropriate to use anata . This is because anata is used to refer to people of equal or lower status, and one's teacher has higher status. Japanese nouns have no grammatical number, gender or article aspect. The noun hon ( 本 ) may refer to a single book or several books; hito ( 人 ) can mean "person" or "people", and ki ( 木 ) can be "tree" or "trees". Where number
3100-701: Is associated with comedy (see Kansai dialect ). Dialects of Tōhoku and North Kantō are associated with typical farmers. The Ryūkyūan languages, spoken in Okinawa and the Amami Islands (administratively part of Kagoshima ), are distinct enough to be considered a separate branch of the Japonic family; not only is each language unintelligible to Japanese speakers, but most are unintelligible to those who speak other Ryūkyūan languages. However, in contrast to linguists, many ordinary Japanese people tend to consider
3224-495: Is basically a cut-down version of Dolby SR and uses many of the same noise reduction techniques. Dolby S is capable of 10 dB of noise reduction at low frequencies and up to 24 dB of noise reduction at high frequencies. Magnetic tape is inherently non-linear in nature due to hysteresis of the magnetic material. If an analog signal were recorded directly onto magnetic tape, its reproduction would be extremely distorted due to this non-linearity . To overcome this,
3348-466: Is better documentation of Late Middle Japanese phonology than for previous forms (for instance, the Arte da Lingoa de Iapam ). Among other sound changes, the sequence /au/ merges to /ɔː/ , in contrast with /oː/ ; /p/ is reintroduced from Chinese; and /we/ merges with /je/ . Some forms rather more familiar to Modern Japanese speakers begin to appear – the continuative ending - te begins to reduce onto
3472-537: Is considered compatible with Dolby B. JVC eventually abandoned the ANRS standard in favor of official Dolby B support; some JVC decks exist whose noise-reduction toggles have a combined "ANRS / Dolby B" setting. In the early 1970s, some expected Dolby NR to become normal in FM radio broadcasts and some tuners and amplifiers were manufactured with decoding circuitry; there were also some tape recorders with
3596-509: Is correlated with the sex of the speaker and the social situation in which they are spoken: men and women alike in a formal situation generally refer to themselves as watashi ( 私 , literally "private") or watakushi (also 私 , hyper-polite form), while men in rougher or intimate conversation are much more likely to use the word ore ( 俺 "oneself", "myself") or boku . Similarly, different words such as anata , kimi , and omae ( お前 , more formally 御前 "the one before me") may refer to
3720-492: Is effective from approximately 1 kHz upwards; the noise reduction that is provided is 3 dB at 600 Hz, 6 dB at 1.2 kHz, 8 dB at 2.4 kHz, and 10 dB at 5 kHz. The width of the noise reduction band is variable, as it is designed to be responsive to both the amplitude and the frequency distribution of the signal. It is thus possible to obtain significant amounts of noise reduction down to quite low frequencies without causing audible modulation of

3968-755: Is less common. In terms of mutual intelligibility , a survey in 1967 found that the four most unintelligible dialects (excluding Ryūkyūan languages and Tōhoku dialects ) to students from Greater Tokyo were the Kiso dialect (in the deep mountains of Nagano Prefecture ), the Himi dialect (in Toyama Prefecture ), the Kagoshima dialect and the Maniwa dialect (in Okayama Prefecture ). The survey
4092-420: Is often called a topic-prominent language , which means it has a strong tendency to indicate the topic separately from the subject, and that the two do not always coincide. The sentence Zō wa hana ga nagai ( 象は鼻が長い ) literally means, "As for elephant(s), (the) nose(s) (is/are) long". The topic is zō "elephant", and the subject is hana "nose". Japanese grammar tends toward brevity; the subject or object of

The first was Dolby A , a professional broadband noise reduction system for recording studios that was first demonstrated in 1965, but the best-known is Dolby B (introduced in 1968), a sliding band system for the consumer market, which helped make high fidelity practical on cassette tapes , which used

"hair of the eye"); modern mieru ("to be visible") and kikoeru ("to be audible") retain a mediopassive suffix - yu(ru) ( kikoyu → kikoyuru (the attributive form, which slowly replaced the plain form starting in the late Heian period) → kikoeru (all verbs with the shimo-nidan conjugation pattern underwent this same shift in Early Modern Japanese )); and
4464-711: Is the WM1ZM2 player. Walkman cassette players were very popular during the 1980s, which led to "walkman" becoming an genericized label term for personal compact stereos of any producer or brand. 220 million cassette-type Walkmen were sold by the end of production in 2010; including digital Walkman devices such as DAT , MiniDisc , CD (originally Discman then renamed the CD ;Walkman) and memory-type media players , it has sold approximately 400 million at this time. The Walkman brand has also been applied to transistor radios , and Sony Ericsson mobile phones. In March 1979, at

It has around 123 million speakers, primarily in Japan , the only country where it is the national language , and within the Japanese diaspora worldwide. The Japonic family also includes the Ryukyuan languages and the variously classified Hachijō language . There have been many attempts to group the Japonic languages with other families such as

For others that represent a change of state, the -te iru form indicates a perfect aspect. For example, kite iru means "They have come (and are still here)", but tabete iru means "They are eating". Questions (both with an interrogative pronoun and yes/no questions) have
4960-405: Is why some linguists do not classify Japanese "pronouns" as pronouns, but rather as referential nouns, much like Spanish usted (contracted from vuestra merced , "your ( majestic plural ) grace") or Portuguese você (from vossa mercê ). Japanese personal pronouns are generally used only in situations requiring special emphasis as to who is doing what to whom. The choice of words used as pronouns

Little is known of the language's prehistory, or when it first appeared in Japan. Chinese documents from the 3rd century AD recorded a few Japanese words, but substantial Old Japanese texts did not appear until the 8th century.

Rival Apple 's iPod range became a large success in the market, hindering Walkman sales internationally, though it fared better domestically. The Network Walkman for several years had paltry market share and had also been struggling against numerous other rivals such as Creative , Rio , Mpio and iRiver , although sales and share did eventually increase fivefold in 2005 and continued improving, but remained small. Its pricing policy, SonicStage software and lack of MP3 support in earlier years have been suggested factors of its performance. Its U.S. market share in 2006

Japanese has no official status in Japan, but is the de facto national language of the country. There is a form of the language considered standard : hyōjungo ( 標準語 ) , meaning "standard Japanese", or kyōtsūgo ( 共通語 ) , "common language", or even "Tokyo dialect" at times. The meanings of
5704-806: The de facto standard Japanese had been the Kansai dialect , especially that of Kyoto . However, during the Edo period, Edo (now Tokyo) developed into the largest city in Japan, and the Edo-area dialect became standard Japanese. Since the end of Japan's self-imposed isolation in 1853, the flow of loanwords from European languages has increased significantly. The period since 1945 has seen many words borrowed from other languages—such as German, Portuguese and English. Many English loan words especially relate to technology—for example, pasokon (short for "personal computer"), intānetto ("internet"), and kamera ("camera"). Due to

Approximately 12% of Hawaii residents speak Japanese, with an estimated 12.6% of the population of Japanese ancestry in 2008. Japanese emigrants can also be found in Peru , Argentina , Australia (especially in the eastern states), Canada (especially in Vancouver , where 1.4% of the population has Japanese ancestry),

It provides about 15 dB noise reduction ( A-weighted ) in the 2 kHz to 8 kHz region where the ear is highly sensitive and most tape hiss is concentrated. Its noise reduction effect results from the dual-level (consisting of

In 1990 Sony released portable Digital Audio Tape (DAT) players marketed as DAT Walkman . It was extended further in 1992 for MiniDisc players with the MD Walkman brand. From 1997, Sony's Discman range of portable compact disc (CD) players started to rebrand as CD Walkman . In 2000,

#17327581768506448-466: The Dolby variants work by companding : compressing the dynamic range of the sound during recording, and expanding it during playback. When recording a signal on magnetic tape, there is a low level of noise in the background which sounds like hissing. One solution to this issue is to use low-noise tape, which records more signal, and less noise. Other solutions are to run the tape at a higher speed or use

The 1980s was the decade of the intensive development of the Walkman lineup. In 1981 Sony released the second Walkman model, the WM-2, which was significantly smaller than the TPS-L2 thanks to the "inverse" mounting of the power-operated magnetic head and soft-touch buttons. Sony applied

In the market, the Walkman's success also led to great adoption of the Compact Cassette format. Within a few years, cassettes were outselling vinyl records, and would continue to do so until the compact disc (CD) overtook cassette sales in 1991. In German-speaking countries,

A group described as Tanaka-san-tachi may include people not named Tanaka. Some Japanese nouns are effectively plural, such as hitobito "people" and wareware "we/us", while the word tomodachi "friend" is considered singular, although plural in form.

The calibration of the expansion (decoding) unit for magnetic tape uses a flux level of 185 nWb/m, which is the level used on industry calibration tapes such as those from Ampex; this is set to 0 VU on the tape recorder playback and to Dolby Level on the noise reduction unit. In the record (compression or encoding) mode, a characteristic tone (Dolby Tone) generated inside

Millions used the Walkman during exercise, marking the beginning of the aerobics fad. Between 1987 and 1997, the height of the Walkman's popularity, the number of people who said they walked for exercise increased by 30%. Other firms, including Aiwa , Panasonic and Toshiba , produced similar products, and in 1983 cassettes outsold vinyl for

Late Middle Japanese covers the years from 1185 to 1600, and is normally divided into two sections, roughly equivalent to the Kamakura period and the Muromachi period , respectively. The later forms of Late Middle Japanese are the first to be described by non-native sources, in this case the Jesuit and Franciscan missionaries; and thus there

The Walkman has been cited as influencing people's relationship with music and technology, due to its "solitary" and "personal" nature, as users were listening to their music of choice instead of radio. It has been seen as a precursor of personal mainstream tech possessions such as personal computers or mobile phones. Headphones also started to be worn in public. This caused safety controversies in

This continued in some record labels and hardware manufacturers even after Dolby C had been introduced, during the period when the new standard was relatively little-known. JVC 's ANRS [ ja ] system, used in place of Dolby B on earlier JVC cassette decks,
8804-455: The flow of loanwords from European languages increased significantly, and words from English roots have proliferated. Japanese is an agglutinative , mora -timed language with relatively simple phonotactics , a pure vowel system, phonemic vowel and consonant length, and a lexically significant pitch-accent . Word order is normally subject–object–verb with particles marking the grammatical function of words, and sentence structure
8928-609: The genitive particle ga remains in intentionally archaic speech. Early Middle Japanese is the Japanese of the Heian period , from 794 to 1185. It formed the basis for the literary standard of Classical Japanese , which remained in common use until the early 20th century. During this time, Japanese underwent numerous phonological developments, in many cases instigated by an influx of Chinese loanwords . These included phonemic length distinction for both consonants and vowels , palatal consonants (e.g. kya ) and labial consonant clusters (e.g. kwa ), and closed syllables . This had
9052-412: The ideal reflections of the viewing audience. Sony implemented a marketing strategy, hiring young adults to walk around in public wearing a Walkman, offering nearby people to test out the product. Sony also hired actors to pose with the Walkman around the streets of Tokyo as an additional form of promotion. A major component of the Walkman advertising campaign was overspecialization of the device. Prior to
9176-450: The incoming off-tape signal and noise. After playback de-emphasis is complete, the apparent noise in the output signal is reduced, and this process should not produce any other effect noticeable to the listener other than reduced background noise. However, playback without noise reduction produces a noticeably brighter sound. The correct calibration of the recording and playback circuitry is critical in order to ensure faithful reproduction of
9300-430: The language, affecting the phonology of Early Middle Japanese . Late Middle Japanese (1185–1600) saw extensive grammatical changes and the first appearance of European loanwords . The basis of the standard dialect moved from the Kansai region to the Edo region (modern Tokyo ) in the Early Modern Japanese period (early 17th century–mid 19th century). Following the end of Japan's self-imposed isolation in 1853,
9424-458: The languages of the original Jōmon inhabitants, including the ancestor of the modern Ainu language . Because writing had yet to be introduced from China, there is no direct evidence, and anything that can be discerned about this period must be based on internal reconstruction from Old Japanese , or comparison with the Ryukyuan languages and Japanese dialects . The Chinese writing system
9548-449: The languages. Okinawan Japanese is a variant of Standard Japanese influenced by the Ryūkyūan languages, and is the primary dialect spoken among young people in the Ryukyu Islands . Modern Japanese has become prevalent nationwide (including the Ryūkyū islands) due to education , mass media , and an increase in mobility within Japan, as well as economic integration. Japanese is a member of
9672-427: The large quantity of English loanwords, modern Japanese has developed a distinction between [tɕi] and [ti] , and [dʑi] and [di] , with the latter in each pair only found in loanwords. Although Japanese is spoken almost exclusively in Japan, it has also been spoken outside of the country. Before and during World War II , through Japanese annexation of Taiwan and Korea , as well as partial occupation of China ,
9796-410: The low level of tape noise with no signal. When the music is loud, the low background hiss level is not noticeable, but when the music is soft or in silence, most or all of what can be heard is the noise. If the recording level is adjusted so that the music is always loud, then the low-level noise would not be audible. One cannot simply increase the volume of the recording to achieve this end; tapes have
9920-453: The noise by the signal ("breathing"). From the mid-1970s, Dolby B became standard on commercially pre-recorded music cassettes even though some low-end equipment lacked decoding circuitry, although it allows for acceptable playback on such equipment. Most pre-recorded cassettes use this variant. VHS video recorders used Dolby B on linear stereo audio tracks. Prior to the introduction of later consumer variants (Dolby C being
10044-473: The noise reduction unit is set to 0 VU on the tape recorder and to 185 nWb/m on the tape. The Dolby A-type system also saw some use as the method of noise reduction in optical sound for motion pictures. Dolby B-type noise reduction was developed after Dolby A, and it was introduced in 1968. It consisted of a single sliding band system providing about 9 dB of noise reduction ( A-weighted ), primarily for use with cassette tapes . It
10168-425: The only strict rule of word order is that the verb must be placed at the end of a sentence (possibly followed by sentence-end particles). This is because Japanese sentence elements are marked with particles that identify their grammatical functions. The basic sentence structure is topic–comment . For example, Kochira wa Tanaka-san desu ( こちらは田中さんです ). kochira ("this") is the topic of the sentence, indicated by
10292-431: The original program content. The calibration can easily be upset by poor-quality tape, dirty or misaligned recording/playback heads, or using inappropriate bias levels/frequency for the tape formulation, as well as tape speed when recording or duplicating. This can manifest itself as muffled-sounding playback, or " breathing " of the noise level as the volume level of the signal varies. On some high-end consumer equipment,
10416-409: The original signal volume. For instance, in Dolby B, a low-level signal will be boosted by 10 dB , while signals at the "Dolby Level", +3 VU , receive no signal modification at all. Between the two limits, a varying level of pre-emphasis is applied. On playback, the opposite process is applied (de-emphasis), based on the relative signal component above 1 kHz. Thus, as this portion of
10540-470: The out-group gives a benefit to the in-group, and "up" to indicate the in-group gives a benefit to the out-group. Here, the in-group includes the speaker and the out-group does not, and their boundary depends on context. For example, oshiete moratta ( 教えてもらった ) (literally, "explaining got" with a benefit from the out-group to the in-group) means "[he/she/they] explained [it] to [me/us]". Similarly, oshiete ageta ( 教えてあげた ) (literally, "explaining gave" with
10664-415: The particle wa . The verb desu is a copula , commonly translated as "to be" or "it is" (though there are other verbs that can be translated as "to be"), though technically it holds no meaning and is used to give a sentence 'politeness'. As a phrase, Tanaka-san desu is the comment. This sentence literally translates to "As for this person, (it) is Mx Tanaka." Thus Japanese, like many other Asian languages,
10788-501: The presence of strong high-frequency signals, making it possible to record at a higher signal level. The original Dolby HX, where HX stands for Headroom eXtension , was invented in 1979 by Kenneth Gundry of Dolby Laboratories, and was rejected by the industry for its inherent flaws. Bang & Olufsen continued work in the same direction, which resulted in a 1981 patent (EP 0046410) by Jørgen Selmer Jensen. Bang & Olufsen immediately licensed HX-Pro to Dolby Laboratories, stipulating
10912-481: The proposed larger Altaic family, or to various Southeast Asian languages , especially Austronesian . None of these proposals have gained wide acceptance (and the Altaic family itself is now considered controversial). As it stands, only the link to Ryukyuan has wide support. Other theories view the Japanese language as an early creole language formed through inputs from at least two distinct language groups, or as
11036-505: The request of Masaru Ibuka , the audio department modified the small recorder used by journalists, "Pressman", into a smaller recorder. After many people praised the good sound quality evaluation, under the leadership of Akio Morita , SONY began to launch the Walkman in July 1979. Akio Morita positioned Walkman in the youth market, emphasized youth, vitality, and fashion, and created a headset culture. In February 1980, he began to sell Walkman to
11160-641: The required Dolby C decoding circuitry. Some of this harshness can be mitigated by using Dolby B on playback, which serves to reduce the strength of the high frequencies. With Dolby C-type processing, noise reduction begins two octaves lower in frequency in an attempt to maintain a psychoacoustically-uniform noise floor. In the region above 8 kHz, where the ear is less sensitive to noise, special spectral-skewing and anti-saturation networks come into play. These circuits prevent cross modulation of low frequencies with high frequencies, suppress tape saturation when large signal transients are present, and increase
11284-414: The sale of certain Walkman models. Sony cofounder Masaru Ibuka used Sony's bulky TC-D5 cassette recorder to listen to music while traveling for business. He asked the executive deputy president Norio Ohga to design a playback-only stereo version optimized for walking. The metal-cased blue-and-silver Walkman TPS-L2, the world's first low-cost personal stereo , went on sale in Japan on July 1, 1979, and
11408-459: The same structure as affirmative sentences, but with intonation rising at the end. In the formal register, the question particle -ka is added. For example, ii desu ( いいです ) "It is OK" becomes ii desu-ka ( いいですか。 ) "Is it OK?". In a more informal tone sometimes the particle -no ( の ) is added instead to show a personal interest of the speaker: Dōshite konai-no? "Why aren't (you) coming?". Some simple queries are formed simply by mentioning
11532-451: The same time that multitrack recording became standard. The input signal is split into frequency bands by four filters with 12 dB per octave slopes, with cutoff frequencies (3 dB down points) as follows: low-pass at 80 Hz; band-pass from 80 Hz to 3 kHz; a high-pass from 3 kHz; and another high-pass at 9 kHz. (The stacking of contributions from the two high-pass bands allows greater noise reduction in
11656-404: The signal decreases in amplitude, the higher frequencies are progressively increasingly attenuated, which also reduces in level the constant background noise on the tape when and where it would be most noticeable. The two processes (pre- and de-emphasis) are intended to cancel each other out as far as the actual recorded program material is concerned. During playback, only de-emphasis is applied to
11780-478: The sound of a CD and a Dolby S encoded cassette. Dolby S mostly appeared on high-end audio equipment and was never widely used. Dolby S is much more resistant to playback problems caused by noise from the tape transport mechanism than Dolby C. Likewise, Dolby S was also claimed to have playback compatibility with Dolby B in that a Dolby S recording could be played back on older Dolby B equipment with some benefit being realized. It
11904-439: The speaker, the listener, and persons mentioned. The Japanese writing system combines Chinese characters , known as kanji ( 漢字 , ' Han characters') , with two unique syllabaries (or moraic scripts) derived by the Japanese from the more complex Chinese characters: hiragana ( ひらがな or 平仮名 , 'simple characters') and katakana ( カタカナ or 片仮名 , 'partial characters'). Latin script ( rōmaji ローマ字 )
12028-817: The state as at the time the constitution was written, many of the elders participating in the process had been educated in Japanese during the South Seas Mandate over the island shown by the 1958 census of the Trust Territory of the Pacific that found that 89% of Palauans born between 1914 and 1933 could speak and read Japanese, but as of the 2005 Palau census there were no residents of Angaur that spoke Japanese at home. Japanese dialects typically differ in terms of pitch accent , inflectional morphology , vocabulary , and particle usage. Some even differ in vowel and consonant inventories, although this
12152-481: The street. (grammatically incorrect insertion of a pronoun) But one can grammatically say essentially the same thing in Japanese: 驚いた彼は道を走っていった。 Transliteration: Odoroita kare wa michi o hashitte itta. (grammatically correct) This is partly because these words evolved from regular nouns, such as kimi "you" ( 君 "lord"), anata "you" ( あなた "that side, yonder"), and boku "I" ( 僕 "servant"). This
12276-469: The task of correct level setting. For accurate off-the-tape monitoring during recording on 3-head tape decks, both processes must be employed at once, and circuitry provided to accomplish this is marketed under the "Double Dolby" label. Dolby A-type noise reduction was the Dolby company's first noise reduction system, presented in 1965. It was intended for use in professional recording studios, where it became commonplace, gaining widespread acceptance at
12400-604: The topic with an interrogative intonation to call for the hearer's attention: Kore wa? "(What about) this?"; O-namae wa? ( お名前は？ ) "(What's your) name?". Negatives are formed by inflecting the verb. For example, Pan o taberu ( パンを食べる。 ) "I will eat bread" or "I eat bread" becomes Pan o tabenai ( パンを食べない。 ) "I will not eat bread" or "I do not eat bread". Plain negative forms are i -adjectives (see below) and inflect as such, e.g. Pan o tabenakatta ( パンを食べなかった。 ) "I did not eat bread". Dolby noise-reduction system A Dolby noise-reduction system , or Dolby NR ,
12524-406: The total amount of distortion of the original signal can be reduced and focused only on the problematic frequencies. The differences in the various Dolby products are largely evident in the precise set of frequencies that they use and the amount of modification of the original signal volume that is applied to each of the frequency bands. Within each band, the amount of pre-emphasis applied depends on
12648-419: The two consonants are the moraic nasal followed by a homorganic consonant. Japanese also includes a pitch accent , which is not represented in moraic writing; for example [haꜜ.ɕi] ("chopsticks") and [ha.ɕiꜜ] ("bridge") are both spelled はし ( hashi ) , and are only differentiated by the tone contour. Japanese word order is classified as subject–object–verb . Unlike many Indo-European languages ,
12772-577: The two methods were both used in writing until the 1940s. Bungo still has some relevance for historians, literary scholars, and lawyers (many Japanese laws that survived World War II are still written in bungo , although there are ongoing efforts to modernize their language). Kōgo is the dominant method of both speaking and writing Japanese today, although bungo grammar and vocabulary are occasionally used in modern Japanese for effect. The 1982 state constitution of Angaur , Palau , names Japanese along with Palauan and English as an official language of
12896-480: The two terms (''hyōjungo'' and ''kyōtsūgo'') are almost the same. Hyōjungo or kyōtsūgo is a conception that forms the counterpart of dialect. This normative language was born after the Meiji Restoration ( 明治維新 , meiji ishin , 1868) from the language spoken in the higher-class areas of Tokyo (see Yamanote ). Hyōjungo is taught in schools and used on television and in official communications. It
13020-526: The upper frequencies.) The compander circuit has a threshold of −40 dB, with a ratio of 2:1 for a compression/expansion of 10 dB. This provides about 10 dB of noise reduction increasing to a possible 15 dB at 15 kHz, according to articles written by Ray Dolby and published by the Audio Engineering Society (October 1967) and Audio (June/July 1968). As with the Dolby B-type system, correct matching of
13144-560: The use of "Walkman" became generic, meaning a personal stereo of any make, to a degree that the Austrian Supreme Court of Justice ruled in 2002 that Sony could not prevent others from using the term "Walkman" to describe similar goods. It is therefore an example of what marketing experts call the " genericide " of a brand. A large statue of a Sports Walkman FM was erected in Tokyo's Ginza district in 2019 in celebration of
13268-407: The verb (e.g. yonde for earlier yomite ), the -k- in the final mora of adjectives drops out ( shiroi for earlier shiroki ); and some forms exist where modern standard Japanese has retained the earlier form (e.g. hayaku > hayau > hayɔɔ , where modern Japanese just has hayaku , though the alternative form is preserved in the standard greeting o-hayō gozaimasu "good morning"; this ending
13392-424: The volume to overwhelm inherent noise, is known as pre-emphasis, and is found in a number of products. On top of this basic concept, Dolby noise reduction systems add another improvement. This takes into account the fact that tape noise is largely heard at frequencies above 1,000 Hz. It is the lower-frequency sounds that are often loud, like drum beats, so by only applying the companding to certain frequencies,
13516-636: The world, and in November 1980, he began to use the non-standard Japanese and English brands globally. The Walkman has sold more than 250 million units worldwide. When Akio Morita was knighted in October 1992, the headline in the British newspapers The Sun and The Daily Telegraph was "Arise, Sir Sony Walkman" [Doing Cultural Studies: The Story of the Sony Walkman, Paul du Gay] [1] The Compact Cassette
13640-548: The world. Since Japanese first gained the consideration of linguists in the late 19th century, attempts have been made to show its genealogical relation to languages or language families such as Ainu , Korean , Chinese , Tibeto-Burman , Uralic , Altaic (or Ural-Altaic ), Austroasiatic , Austronesian and Dravidian . At the fringe, some linguists have even suggested a link to Indo-European languages , including Greek , or to Sumerian . Main modern theories try to link Japanese either to northern Asian languages, like Korean or
13764-468: Was 1.9%, placing it behind Apple, SanDisk , Creative and Samsung . In Japan its share in 2009–2010 was between 43 and 48%, slightly ahead of Apple. Meanwhile, Sony Computer Entertainment , a Sony division who are not involved in Walkman products, officially described their PlayStation Portable in 2004 as the "21st century Walkman". Walkman portable digital audio and media players are the only Walkman-branded products still being produced today – although
13888-463: Was a huge selling point of the Walkman, especially amongst teens, who greatly contributed to its success. A diversity of features and styles suggested that there would be a product which was "the perfect choice" for each consumer. This method of marketing to an extremely expansive user-base while maintaining the idea that the product was made for each individual "[got] the best of all possible worlds—mass marketing and personal differentiation". Culturally
14012-539: Was based on 12- to 20-second-long recordings of 135 to 244 phonemes , which 42 students listened to and translated word-for-word. The listeners were all Keio University students who grew up in the Kanto region . There are some language islands in mountain villages or isolated islands such as Hachijō-jima island , whose dialects are descended from Eastern Old Japanese . Dialects of the Kansai region are spoken or known by many Japanese, and Osaka dialect in particular
14136-515: Was branded as MS Walkman , shortly before the Walkman brand unification. Most future models would use built-in solid-state flash memory , although hard disk based players were also released from 2004 to 2007. They came with OpenMG copyright protection and, until 2004, exclusively supported Sony's in-house ATRAC format; there was no support for industry-standard MP3 as Sony wanted to protect its records division, Sony BMG , from piracy . Additionally, Walkman-branded mobile phones were also made by
14260-528: Was developed by the Dutch electronics firm Philips and released in August 1963. In the late 1960s, the introduction of prerecorded compact cassettes made it possible to listen to music on portable devices as well as on car stereos, though gramophone records remained the most popular format for home listening. Portable tape players of various designs were available, but none of them were intended to be operated by
14384-600: Was evaluated in Germany between July 1979 and December 1981 by IRT , and field-trialed up to 1984. It was based on the Telefunken High Com broadband compander system, but never introduced commercially in FM broadcasting. Another competing system was FMX , which was based on CX . A fully Dolby B-compatible compander was developed and used on many tape recorders in the former German Democratic Republic in
14508-735: Was imported to Japan from Baekje around the start of the fifth century, alongside Buddhism. The earliest texts were written in Classical Chinese , although some of these were likely intended to be read as Japanese using the kanbun method, and show influences of Japanese grammar such as Japanese word order. The earliest text, the Kojiki , dates to the early eighth century, and was written entirely in Chinese characters, which are used to represent, at different times, Chinese, kanbun , and Old Japanese. As in other texts from this period,
14632-469: Was introduced in 1989. It was intended that Dolby S would become standard on commercial pre-recorded music cassettes in much the same way that Dolby B had in the 1970s, but it came to market when the Compact Cassette was being replaced by the compact disc as the dominant mass market music format. Dolby Labs claimed that most members of the general public could not differentiate between
14756-474: Was lost immediately following its composition.) This set of morae shrank to 67 in Early Middle Japanese , though some were added through Chinese influence. Man'yōgana also has a symbol for /je/ , which merges with /e/ before the end of the period. Several fossilizations of Old Japanese grammatical elements remain in the modern language – the genitive particle tsu (superseded by modern no )
14880-640: Was much simpler than Dolby A and therefore much less expensive to implement in consumer products. Dolby B recordings are acceptable when played back on equipment that does not possess a Dolby B decoder, such as many inexpensive portable and car cassette players. Without the de-emphasis effect of the decoder, the sound will be perceived as brighter as high frequencies are emphasized, which can be used to offset "dull" high-frequency response in inexpensive equipment. However, Dolby B provides less effective noise reduction than Dolby A, generally by an amount of more than 3 dB. The Dolby B system
15004-408: Was of lower fidelity. As a result of their narrow tracks and slow speed, cassettes make tape hiss a very severe problem. Dolby noise reduction is a form of dynamic pre-emphasis employed during recording, plus a form of dynamic de-emphasis used during playback, which work in tandem to improve the signal-to-noise ratio . The signal-to-noise ratio is simply how large the music signal is compared to
15128-502: Was possible. Dolby C first appeared on higher-end cassette decks in the 1980s. The first commercially available cassette deck with Dolby C was the NAD 6150C, which came onto the market around 1981. Dolby C was also used on professional video equipment for the audio tracks of the Betacam and Umatic SP videocassette formats. In Japan, the first cassette deck with Dolby C
15252-477: Was sold for around ¥33,000 (or $ 150.00). Though Sony predicted it would sell about 5,000 units a month, it sold more than 30,000 in the first two months. The Walkman was followed by a series of international releases; as overseas sales companies objected to the wasei-eigo name, it was sold under several names, including Sound-about in the United States, Freestyle in Australia and Sweden, and Stowaway in
15376-486: Was the AD-FF5 from Aiwa . Cassette decks with Dolby C also included Dolby B for backward compatibility, and were usually labeled as having "Dolby B-C NR". The Dolby SR (Spectral Recording) system, introduced in 1986, was the company's second professional noise reduction system. It is a much more aggressive noise reduction approach than Dolby A. It attempts to maximize the recorded signal at all times using
