The MPU-401 , where MPU stands for MIDI Processing Unit , is an important but now obsolete interface for connecting MIDI -equipped electronic music hardware to personal computers . It was designed by Roland Corporation , which also co-authored the MIDI standard.
78-475: Released around 1984, the original MPU-401 was an external breakout box providing MIDI IN/MIDI OUT/MIDI THRU/TAPE IN/TAPE OUT/MIDI SYNC connectors, for use with a separately-sold interface card/cartridge ("MPU-401 interface kit") inserted into a computer system. For this setup, the following "interface kits" were made: In 2014 hobbyists built clones of the MIF-IPC-A card for PCs. Later, Roland would put most of
156-617: A Yamaha OPL4 sound chip. Prior to the Moonsound, there were also sound cards called MSX Music and MSX Audio for the system, which uses OPL2 and OPL3 chipsets. The Apple II computers, which did not have sound capabilities beyond rapidly clicking a speaker until the IIGS , could use plug-in sound cards from a variety of manufacturers . The first, in 1978, was ALF's Apple Music Synthesizer , with 3 voices; two or three cards could be used to create 6 or 9 voices in stereo. Later ALF created
234-473: A computer under the control of computer programs . The term sound card is also applied to external audio interfaces used for professional audio applications. Sound functionality can also be integrated into the motherboard , using components similar to those found on plug-in cards. The integrated sound system is often still referred to as a sound card . Sound processing hardware is also present on modern video cards with HDMI to output sound along with
312-468: A digital-to-analog converter (DAC), which converts recorded or generated digital signal data into an analog format. The output signal is connected to an amplifier, headphones, or external device using standard interconnects, such as a TRS phone connector . A common external connector is the microphone connector. Input through a microphone connector can be used, for example, by speech recognition or voice over IP applications. Most sound cards have
390-445: A line in connector for an analog input from a sound source that has higher voltage levels than a microphone. In either case, the sound card uses an analog-to-digital converter (ADC) to digitize this signal. Some cards include a sound chip to support the production of synthesized sounds, usually for real-time generation of music and sound effects using minimal data and CPU time. The card may use direct memory access to transfer
468-551: A Music Quest PC MIDI Card 8BIT clone. In 2017/2018 hobbyists developed a revision of the Music Quest PC MIDI Card 8BIT clone that includes a wavetable header in analogy of the Roland MPU-401AT. The MPU-401 can work in two modes, normal mode and UART mode . "Normal mode" would provide the host system with an 8-track sequencer, MIDI clock output, SYNC 24 signal output, Tape Sync and a metronome; as

Even today, the tendency is still to mix multiple sound streams in software, except in products specifically intended for gamers or professional musicians. As of 2024, sound cards are not commonly programmed with the audio loopback systems commonly called stereo mix , wave out mix , mono mix or what u hear , which previously allowed users to digitally record output otherwise only accessible to speakers. Lenovo and other manufacturers fail to implement
702-587: A clone of the PCjr, duplicated this functionality, with the Tandy 1000 TL/SL/RL models adding digital sound recording and playback capabilities. Many games during the 1980s that supported the PCjr's video standard (described as Tandy-compatible , Tandy graphics , or TGA ) also supported PCjr/Tandy 1000 audio. In the late 1990s, many computer manufacturers began to replace plug-in sound cards with an audio codec chip (a combined audio AD / DA -converter) integrated into

Professional sound cards are sound cards optimized for high-fidelity, low-latency multichannel sound recording and playback. Their drivers usually follow the Audio Stream Input/Output protocol for use with professional sound engineering and music software. Professional sound cards are usually described as audio interfaces , and sometimes have
1170-442: A profitable company. In 1988, Turtle Beach began to work on developing its first hardware product, a hard disk–based audio editing system. Among the first of its kind, the product was named the "56K digital recording system" and was released in 1990. In 1990, Turtle Beach began developing its second PC sound card . This card used high quality A/D and D/A , a high quality synthesizer from eMu, and an onboard DSP chip. This product
1248-517: A result of these features, it is often called "intelligent mode". Compare this to UART mode, which reduces the MPU-401 to simply relaying in-/outcoming MIDI data bytes. As computers became more powerful, the features offered in "intelligent mode" became obsolete. Implementing these in the host system's software was more efficient. Specific hardware was no longer required. As a result, the UART mode became
1326-572: A software downmix at a fixed sampling rate. Modern low-cost integrated sound cards (i.e., those built into motherboards) such as audio codecs like those meeting the AC'97 standard and even some lower-cost expansion sound cards still work this way. These devices may provide more than two sound output channels (typically 5.1 or 7.1 surround sound ), but they usually have no actual hardware polyphony for either sound effects or MIDI reproduction – these tasks are performed entirely in software. This
1404-704: A sound card called the Creative Music System (C/MS) at about the same time. Although the C/MS had twelve voices to AdLib's nine and was a stereo card while the AdLib was mono, the basic technology behind it was based on the Philips SAA1099 chip which was essentially a square-wave generator. It sounded much like twelve simultaneous PC speakers would have except for each channel having amplitude control, and failed to sell well, even after Creative renamed it
1482-458: A speaker configuration such as 2.0 (stereo), 2.1 (stereo and sub woofer), 5.1 (surround), or other configurations. Sometimes, the terms voice and channel are used interchangeably to indicate the degree of polyphony, not the output speaker configuration. For example, much older sound chips could accommodate three voices, but only one output audio channel (i.e., a single mono output), requiring all voices to be mixed together. Later cards, such as

In general, consumer-grade sound cards impose several restrictions and inconveniences that would be unacceptable to an audio professional. Consumer sound cards are also limited in the effective sampling rates and bit depths they can actually manage and have lower numbers of less flexible input channels. Professional studio recording use typically requires more than
1872-454: Is similar to the way inexpensive softmodems perform modem tasks in software rather than in hardware. In the early days of wavetable synthesis , some sound card manufacturers advertised polyphony solely on the MIDI capabilities alone. In this case, typically, the card is only capable of two channels of digital sound and the polyphony specification solely applies to the number of MIDI instruments
1950-494: The AdLib sound card, had a 9-voice polyphony combined in 1 mono output channel. Early PC sound cards had multiple FM synthesis voices (typically 9 or 16) which were used for MIDI music. The full capabilities of advanced cards are often not fully used; only one (mono) or two ( stereo ) voice(s) and channel(s) are usually dedicated to playback of digital sound samples, and playing back more than one digital sound sample usually requires

Early Mockingboard models ranged from 3 voices in mono, while some later designs had 6 voices in stereo. Some software supported use of two Mockingboard cards, which allowed 12-voice music and sound. A 12-voice, single-card clone of the Mockingboard called

It is considered one of the leading gaming audio brands. Gaming headsets have been Turtle Beach's primary product offering since around 2005. It initially began releasing headsets for PCs and consoles of that generation including
2340-696: The Xbox 360 , Wii , and the PlayStation 3 . The early models were often given the Ear Force branding with a letter or number designation to differentiate between consoles (e.g. headsets for the Xbox 360 were a part of the "Ear Force X" series while those for the PlayStation 3 were part of the "Ear Force P" series). Turtle Beach headsets are generally cross-compatible between current-generation consoles like

Early sound cards for
3354-625: The PC's limited sound capability prevented it from becoming the leading home computer, that it needed a $ 49–79 sound card with better capability than current products, and that once such hardware was widely installed, their companies would support it. Sierra On-Line , which had pioneered supporting EGA and VGA video, and 3-1/2" disks, promised that year to support the AdLib, IBM Music Feature, and Roland MT-32 sound cards in its games. A 1989 Computer Gaming World survey found that 18 of 25 game companies planned to support AdLib, six Roland and Covox, and seven Creative Music System/Game Blaster. One of
3432-702: The Sound Blaster brought digital audio playback to the PC. Many game companies also supported the MT-32, but supported the Adlib card as an alternative because of the latter's higher market base. The adoption of the MT-32 led the way for the creation of the MPU-401 , Roland Sound Canvas and General MIDI standards as the most common means of playing in-game music until the mid-1990s. Early ISA bus sound cards were half-duplex , meaning they couldn't record and play digitized sound simultaneously. Later, ISA cards like

The card also included a game port for adding a joystick , and the capability to interface to MIDI equipment using the game port and a special cable. With AdLib compatibility and more features at nearly the same price, most buyers chose the Sound Blaster. It eventually outsold the AdLib and dominated
3588-563: The Sound Blaster design in multimedia and entertainment titles meant that future sound cards such as Media Vision 's Pro Audio Spectrum and the Gravis Ultrasound had to be Sound Blaster compatible if they were to sell well. Until the early 2000s, when the AC'97 audio standard became more widespread and eventually usurped the SoundBlaster as a standard due to its low cost and integration into many motherboards, Sound Blaster compatibility

In some cases, the differences between one console-specific model and another are cosmetic. As of 2018, Turtle Beach sells a number of wired and wireless headsets under several different families. These include: Elite (Elite Pro 2 + SuperAmp, Elite SuperAmp, Elite Pro Tournament Gaming Headset, Elite 800,); Stealth (Stealth 700, Stealth 600, Stealth 350VR, Stealth 300); Recon (Recon 200, Recon Camo, Recon 150, Recon 50, Recon Chat); Atlas (Elite Atlas, Atlas Three, Atlas One); and there are also standalone products, including
3822-478: The Stream Mic and Battle Buds. Recon products are generally entry-level and offer great game sound and microphone performance to better immerse players in their game and to allow them to communicate with other online players. Stealth products add premium features like wireless connectivity, surround sound, larger speakers, memory foam , etc. Elite series models are generally considered professional level and/or high-end gaming headsets. The Atlas series of headsets

Many models are console-specific, but share the same branding and can often be used across platforms (e.g. the Stealth 300 has a model for both the Xbox One and the PlayStation 4, but both are technically compatible with one another and the Nintendo Switch, and PC, etc.). Certain features on console-specific models may not transfer from one platform to another. For instance,
3978-530: The companies Sierra partnered with were Roland and AdLib, opting to produce in-game music for King's Quest 4 that supported the MT-32 and AdLib Music Synthesizer. The MT-32 had superior output quality, due in part to its method of sound synthesis as well as built-in reverb. Since it was the most sophisticated synthesizer they supported, Sierra chose to use most of the MT-32's custom features and unconventional instrument patches, producing background sound effects (e.g., chirping birds, clopping horse hooves, etc.) before

When game company Sierra On-Line opted to support add-on music hardware in addition to built-in hardware such as the PC speaker and built-in sound capabilities of the IBM PCjr and Tandy 1000 , what could be done with sound and music on the IBM PC changed dramatically. Two of
5616-410: Was called "MultiSound." The MultiSound product competed with more established products of the day from Advanced Gravis (now defunct), Ad Lib, Inc. (now defunct), Creative Labs , and Media Vision . CCRMA 's Music Kit and DSP Tools running on Motorola 56001 DSP, initially developed for NeXTcube system, was later ported on NeXTSTEP with Turtle Beach Fiji/Pinnacle DSP cards. In December 1996,
5694-425: Was designed specifically for use in PC gaming. The newest series, Battle Buds, is a set of gaming earbuds designed to be compatible with mobile devices along with PCs and all consoles. Turtle Beach has also developed sound cards , MIDI synthesizers, and various audio software packages and network audio devices. In 1988, Turtle Beach developed its first product, a hard disk–based audio editing system. The product
5772-414: Was introduced in the early 1980s, and quadraphonic sound came in 1989. This was shortly followed by 5.1 channel audio. The latest sound cards support up to 8 audio channels for the 7.1 speaker setup. A few early sound cards had sufficient power to drive unpowered speakers directly – for example, two watts per channel. With the popularity of amplified speakers, sound cards no longer have
5850-409: Was named the "56K digital recording system" and was released in 1990 and was considered the first of its kind. Its card, 56K-PC, was based on a Motorola 56000 DSP chip, and offered non linear playlist editing of stereo audio files. The 56K system was popular among radio stations and mastering studios because it replayed exactly the same digital stream that it recorded. The company has also developed
5928-548: Was released in 2004, again specified the use of a codec chip, and slowly gained acceptance. As of 2011, most motherboards have returned to using a codec chip, albeit an HD Audio compatible one, and the requirement for Sound Blaster compatibility relegated to history. Many home computers have their own motherboard-integrated sound devices: Commodore 64 , Amiga , PC-88 , FM-7 , FM Towns , Sharp X1 , X68000 , BBC Micro , Electron , Archimedes , Atari 8-bit computers , Atari ST , Atari Falcon , Amstrad CPC , later revisions of
6006-648: Was the Gooch Synthetic Woodwind , a music device for PLATO terminals , and is widely hailed as the precursor to sound cards and MIDI. It was invented in 1972. Certain early arcade machines made use of sound cards to achieve playback of complex audio waveforms and digital music, despite being already equipped with onboard audio. An example of a sound card used in arcade machines is the Digital Compression System card, used in games from Midway . For example, Mortal Kombat II on
6084-453: Was the first low cost sampling device that allowed musicians to play realistic choirs, pianos, horns, and other instruments in their performances. The software, called "Vision", connected the Mirage to a PC and used the PC's screen and graphics to make the programming and editing of sounds much easier. Ensoniq decided to resell Vision through their dealer network and Turtle Beach Softworks became
