82-482: Digidesign's flagship software product was Pro Tools , which came in three variants: Pro Tools|HD, Pro Tools LE, and Pro Tools M-Powered. Pro Tools|HD required a Digidesign TDM system and interface, and was intended for professional recording studios. Pro Tools LE was a complete package intended for home users and some post-production facilities. The package included the Pro Tools LE software and hardware such as

164-407: A virtual mixer . 16-bit, 24-bit, and 32-bit float audio bit depths at sample rates up to 192 kHz are supported. Pro Tools supports mixed bit depths and audio formats in a session: BWF / WAV (including WAVE Extensible, RF64 and BW64) and AIFF . It imports and exports MOV video files and ADM BWF files (audio files with Dolby Atmos metadata); it also imports MXF , ACID and REX files and

246-509: A vulnerability . Software patches are often released to fix identified vulnerabilities, but those that remain unknown ( zero days ) as well as those that have not been patched are still liable for exploitation. Vulnerabilities vary in their ability to be exploited by malicious actors, and the actual risk is dependent on the nature of the vulnerability as well as the value of the surrounding system. Although some vulnerabilities can only be used for denial of service attacks that compromise

328-520: A web application —had become the primary method that companies deliver applications. Software companies aim to deliver a high-quality product on time and under budget. A challenge is that software development effort estimation is often inaccurate. Software development begins by conceiving the project, evaluating its feasibility, analyzing the business requirements, and making a software design . Most software projects speed up their development by reusing or incorporating existing software, either in

410-457: A change request. Frequently, software is released in an incomplete state when the development team runs out of time or funding. Despite testing and quality assurance , virtually all software contains bugs where the system does not work as intended. Post-release software maintenance is necessary to remediate these bugs when they are found and keep the software working as the environment changes over time. New features are often added after

492-669: A circuit board for the processor, then developed the software to make it work with Sound Designer. A beta version of the DSP was ready by December 1988. The combination of the hardware and the software was called Sound Tools. Advertised as the "first tapeless studio", it was presented on January 20, 1989, at the NAMM International Music & Sound Expo . The system relied on a NuBus card called Sound Accelerator, equipped with one Motorola 56001 processor. The card provided 16-bit playback and 44.1/48 kHz recording through

574-486: A code's correct and efficient behavior, its reusability and portability , or the ease of modification. It is usually more cost-effective to build quality into the product from the beginning rather than try to add it later in the development process. Higher quality code will reduce lifetime cost to both suppliers and customers as it is more reliable and easier to maintain . Software failures in safety-critical systems can be very serious including death. By some estimates,

656-471: A featured digital audio workstation . They discussed with E-mu the opportunity of using the Emulator III as a platform for their updated software, but E-mu rejected this offer. Therefore, they decided to design both the software and the hardware autonomously. Motorola , which was working on its 56K series of digital signal processors , invited the two to participate in its development. Brooks designed

738-430: A free version: Pro Tools Intro. Pro Tools was developed by UC Berkeley graduates Evan Brooks, who majored in electrical engineering and computer science , and Peter Gotcher. In 1983, the two friends, sharing an interest in music and electronic and software engineering, decided to study the memory mapping of the newly released E-mu Drumulator drum machine to create EPROM sound replacement chips. The Drumulator

820-443: A legal regime where liability for software products is significantly curtailed compared to other products. Source code is protected by copyright law that vests the owner with the exclusive right to copy the code. The underlying ideas or algorithms are not protected by copyright law, but are often treated as a trade secret and concealed by such methods as non-disclosure agreements . Software copyright has been recognized since

902-524: A machine containing one or more HD Core, Accel, or Native cards, the software ran as Pro Tools HD with the complete HD feature set. In all other cases, it ran as Pro Tools 9 standard, with a smaller track count and some advanced features turned off. In response to Apple's decision to include Emagic 's complete line of virtual instruments in Logic Pro in 2004 and following Avid 's acquisition of German virtual instruments developer Wizoo in 2005, Pro Tools 8

984-476: A new implementation of RTAS with multi-threading support and improved performance, Region groups, Instrument tracks, and real-time MIDI processing, introduced with Pro Tools 7 in 2006; VCA and volume trim, introduced with Pro Tools 7.2 in 2006; support for ten track inserts, MIDI Editor, and MIDI Score, introduced with Pro Tools 8 in 2009. Pro Tools | MIX hardware support was dropped with version 6.4.1. Pro Tools LE, first introduced and distributed in 1999 with

1066-475: A new plug-in format for both Native and HDX systems called AAX (an acronym for Avid Audio eXtension). AAX Native replaced RTAS plug-ins and AAX DSP, a specific format running on HDX systems, replaced TDM plug-ins. AAX was developed to provide the future implementation of 64-bit plug-ins, although 32-bit versions of AAX were still used in Pro Tools 10. TDM support was dropped with HDX, while Pro Tools 10 would be

1148-589: A number of products for the Pro Tools platform, including several software plug-ins . They also manufacture a wide variety of hardware add-ons for Pro Tools, such as audio interfaces, MIDI interfaces, Synchronizers , and control surfaces . In the spring of 2005 they introduced a system for live sound mixing called VENUE . Digidesign Software was developed by UC Berkeley graduate Peter Gotcher and his friend Evan Brooks, both majors in electrical engineering and computer science. The first incarnation of today's Pro Tools started life in 1984 as Sound Designer, while

1230-467: A sequencer and more tracks, with the system offering recording at 16-bit and 44.1 kHz. In 1997, Pro Tools had reached 24-bit and 48 track versions. At this point, the migration from more conventional studio technology to the Pro Tools platform took place within the industry. Pro Tools Pro Tools is a digital audio workstation (DAW) developed and released by Avid Technology (formerly Digidesign ) for Microsoft Windows and macOS . It

1312-495: A significant role in the distribution of software products. The first use of the word software is credited to mathematician John Wilder Tukey in 1958. The first programmable computers, which appeared at the end of the 1940s, were programmed in machine language . Machine language is difficult to debug and not portable across different computers. Initially, hardware resources were more expensive than human resources . As programs became complex, programmer productivity became

1394-443: A single FPGA chip but did not mount DSP (audio processing relied on the host system's CPU). Round trip latency at 96 kHz was 0.7 ms for HDX and 1.7 ms for HD Native (with a 64-sample buffer). To maintain performance consistency, HDX products were specified with a fixed maximum number of voices (each voice representing a monophonic channel). Each HDX card enabled 256 simultaneous voices at 44.1/48 kHz; voice count halved when

1476-514: A specific version of the software, downloaded, and run on hardware belonging to the purchaser. The rise of the Internet and cloud computing enabled a new model, software as a service (SaaS), in which the provider hosts the software (usually built on top of rented infrastructure or platforms ) and provides the use of the software to customers, often in exchange for a subscription fee . By 2023, SaaS products—which are usually delivered via

1558-415: A system's availability, others allow the attacker to inject and run their own code (called malware ), without the user being aware of it. To thwart cyberattacks, all software in the system must be designed to withstand and recover from external attack. Despite efforts to ensure security, a significant fraction of computers are infected with malware. Programming languages are the format in which software

1640-467: A two-channel A/D converter (AD In), while the DSP handled signal processing, which included a ten-band graphic equalizer , a parametric equalizer , time stretching with pitch preservation, fade-in/fade-out envelopes, and crossfades ("merging") between two sound files. Sound Tools was bundled with Sound Designer II software, which was, at this time, a simple mono or stereo audio editor running on Mac SE or Mac II ; digital audio acquisition from DAT

1722-421: Is done without overwriting the source files), track compositing with multiple playlists, time compression and expansion , pitch shifting , and faster-than-real-time mixdown. Audio, MIDI , and video tracks are graphically represented on a timeline.

1804-442: Is used for music creation and production, sound for picture ( sound design , audio post-production and mixing ) and, more generally, sound recording , editing, and mastering processes. Pro Tools operates both as standalone software and in conjunction with a range of external analog-to-digital converters and PCIe cards with on-board digital signal processors (DSP). The DSP is used to provide additional processing power to

1886-453: Is written. Since the 1950s, thousands of different programming languages have been invented; some have been in use for decades, while others have fallen into disuse. Some definitions classify machine code —the exact instructions directly implemented by the hardware—and assembly language —a more human-readable alternative to machine code whose statements can be translated one-to-one into machine code—as programming languages. Programs written in

1968-438: The high-level programming languages used to create software share a few main characteristics: knowledge of machine code is not necessary to write them, they can be ported to other computer systems, and they are more concise and human-readable than machine code. They must be both human-readable and capable of being translated into unambiguous instructions for computer hardware. The invention of high-level programming languages

2050-873: The lossy formats MP3 , AAC , M4A , and audio from video files ( MOV , MP4 , M4V ). The legacy SDII format was dropped with Pro Tools 10, although SDII conversion is still possible on macOS. Pro Tools has incorporated video editing capabilities, so users can import and manipulate high-definition video file formats such as XDCAM, MJPG-A, PhotoJPG, DV25, QuickTime , and more. It features time code , tempo maps, elastic audio, and automation ; supports mixing in surround sound , Dolby Atmos and VR sound using Ambisonics . The Pro Tools TDM mix engine, supported until 2011 with version 10, employed 24-bit fixed-point arithmetic for plug-in processing and 48-bit for mixing. Current HDX hardware systems, HD Native and native systems use 32-bit floating-point resolution for plug-ins and 64-bit floating-point summing. The software and

2132-606: The Digi 001 interface, was a specific Pro Tools version in which the signal processing entirely relied on the host CPU. The software required a Digidesign interface to run, which acted as a copy-protection mechanism for the software. Mbox was the entry-level range of the available interface; Digi 001 and Digi 002/003, which also provided a control surface, were the upper range. The Eleven Rack also ran on Pro Tools LE, included in-box DSP processing via an FPGA chip, offloading guitar amp/speaker emulation, and guitar effects plug-in processing to

2214-585: The Disk I/O card incorporated a high-speed SCSI along with DSP chips, while the upgraded DSP Farm PCI card included four Motorola 56002 chips running at 66 MHz. This change of architecture allowed the convergence of Macintosh computers with Intel -based PCs, for which PCI had become the standard internal communication bus. With the PCI version of Digidesign's Audiomedia card in 1997 (Audiomedia III), Sound Tools and Pro Tools could be run on Windows platforms for

2296-456: The M-Box 2 or Digi 003. Pro Tools M-Powered was simply the Pro Tools application adapted to run on M-Audio hardware, and generally comparable in power to an LE system. In 2010, these various editions of Pro Tools were mostly abandoned and it is now being sold by Avid as a singular software product, with the level of functionality dependent on the hardware chosen by the user. Digidesign also made

2378-463: The Motorola 56301 chips mounted on MIX cards; this translated to about twice the power for a single card. A system could combine one HD Core card with up to two HD Process cards, supporting playback for 96/48/12 tracks at 48/96/192 kHz sample rates (with a single HD Core card installed) and 128/64/24 tracks at 48/96/192 kHz sample rates (with one or two HD Process cards). When Apple changed

2460-449: The OSC's engineers who developed Deck, split from Digidesign to focus on releasing lower-cost multi-track software that would run on computers with no additional hardware. This software was known as Session (for stereo-only audio cards) and Session 8 (for multichannel audio interfaces) and was selling for US$ 399. Peter Gotcher felt that the software needed a significant rewrite. Pro Tools II,

2542-474: The Pro Tools environment, allowing a more meticulous and effortless editing workflow (especially on vocals). While consolidating its presence in professional studios, Digidesign began to target the mid-range consumer market in 1999 by introducing the Digi001 bundle, consisting of a rack-mount audio interface with eight inputs and outputs with 24-bit, 44.1/48 kHz capability and MIDI connections. The package

2624-636: The Sound Accelerator card. External synchronization with audio and video tape machines was possible with SMPTE timecode and the Video Slave drivers. The complete system was selling for US$ 6,000. Sound Tools II was launched in 1992 with a new DSP card. Two interfaces were also released: Pro Master 20, providing 20-bit A/D conversion, and Audiomedia II, with improved digital converters and one Motorola 56001 processor running at 33.86 MHz. In 1993, Josh Rosen, Mats Myrberg and John Dalton,

2706-432: The audio engine were adapted to 64-bit architecture from version 11. In 2022, Avid switched Pro Tools from a perpetual license to a subscription model. New users have to choose between three new plans: Pro Tools Artist, which costs $ 9.99 per month or $ 99 per year; Pro Tools Studio, which costs $ 39.99 per month or $ 299 per year; and Pro Tools Flex, which costs $ 99.99 per month or $ 999 per year. Later in 2022, Avid launched

2788-422: The best-selling digital audio workstation. In 1994, Pro Tools 2.5 implemented Digidesign's newly developed time-division multiplexing technology, which allowed routing of multiple digital audio streams between DSP cards. With TDM, up to four NuBus cards could be linked, obtaining a 16-track system, while multiple DSP-based plug-ins could be run simultaneously and in real-time. The wider bandwidth required to run

2870-399: The bottleneck. The introduction of high-level programming languages in 1958 hid the details of the hardware and expressed the underlying algorithms into the code . Early languages include Fortran , Lisp , and COBOL . There are two main types of software: Software can also be categorized by how it is deployed . Traditional applications are purchased with a perpetual license for

There are a variety of software development methodologies , which vary from completing all steps in order to concurrent and iterative models. Software development is driven by requirements taken from prospective users, as opposed to maintenance, which is driven by events such as

3034-400: The cost of poor quality software can be as high as 20 to 40 percent of sales. Despite developers' goal of delivering a product that works entirely as intended, virtually all software contains bugs. The rise of the Internet also greatly increased the need for computer security as it enabled malicious actors to conduct cyberattacks remotely. If a bug creates a security risk, it is called

3116-419: The cost of products. Unlike copyrights, patents generally only apply in the jurisdiction where they were issued. Engineer Capers Jones writes that "computers and software are making profound changes to every aspect of human life: education, work, warfare, entertainment, medicine, law, and everything else". It has become ubiquitous in everyday life in developed countries . In many cases, software augments

3198-668: The decade, while editing features such as Beat Detective (introduced with Pro Tools 5.1 in 2001) and Elastic Audio (introduced with Pro Tools 7.4 in 2007) redefined the workflow adopted in contemporary music production. Other software milestones were background tasks processing (such as fade rendering, file conversion or relinking), real-time insertion of TDM plug-ins during playback, and a browser/database environment introduced with Pro Tools 6 in 2003; Automatic plug-in Delay Compensation (ADC), introduced with Pro Tools 6.4 in 2004 and only available with TDM systems with HD Accel;

3280-466: The expansion slot architecture of the Mac G5 to PCI Express , Digidesign launched a line of PCIe DSP cards that both adopted the new card slot format and slightly changed the combination of chips. HD Process cards were replaced with HD Accel, each mounting nine Motorola 56321 chips running at 200 MHz and each providing twice the power than an HD Process card; track count for systems mounting an HD Accel

3362-410: The final release for Pro Tools | HD Process and Accel systems. Software Software consists of computer programs that instruct the execution of a computer .

3444-585: The first software release fully developed by Digidesign, followed in the same year and addressed its predecessor's weaknesses. The editor and the mixer were merged into a single Pro Tools application that utilized the Digidesign Audio Engine (DAE) created by Peter Richert. DAE was also provided as a separate application to favor hardware support from third-party developers, enabling the use of Pro Tools hardware and plug-ins on other DAWs. Selling more than 8,000 systems worldwide, Pro Tools II became

3526-586: The first time. With the release of Pro Tools | 24 in 1997, Digidesign introduced a new 24-bit interface (the 888|24) and a new PCI card (the d24). The d24 relied on Motorola 56301 processors, offering increased processing power and 24 tracks of 24-bit audio (later increased to 32 tracks with a DAE software update). A SCSI accelerator was required to keep up with the increased data throughput . Digidesign dropped its proprietary SCSI controller in favor of commercially available ones. 64 tracks with dual d24 support were introduced with Pro Tools 4.1.1 in 1998, while

3608-438: The form of commercial off-the-shelf (COTS) or open-source software . Software quality assurance is typically a combination of manual code review by other engineers and automated software testing . Due to time constraints, testing cannot cover all aspects of the software's intended functionality, so developers often focus on the most critical functionality. Formal methods are used in some safety-critical systems to prove

3690-439: The functionality of existing technologies such as household appliances and elevators . Software also spawned entirely new technologies such as the Internet , video games , mobile phones , and GPS . New methods of communication, including email , forums , blogs , microblogging , wikis , and social media , were enabled by the Internet. Massive amounts of knowledge exceeding any paper-based library are now available with

3772-570: The hardware. The introduction of high-level programming languages in 1958 allowed for more human-readable instructions, making software development easier and more portable across different computer architectures . Software in a programming language is run through a compiler or interpreter to execute on the architecture's hardware. Over time, software has become complex, owing to developments in networking , operating systems , and databases . Software can generally be categorized into two main types: The rise of cloud computing has introduced

3854-449: The host computer for processing real-time effects , such as reverb , equalization , and compression and to obtain lower latency audio performance. Like all digital audio workstation software, Pro Tools can perform the functions of a multitrack tape recorder and a mixing console along with additional features that can only be performed in the digital domain, such as non-linear and non-destructive editing (most of audio handling

3936-851: The interface, allowing them to run without taxing the host system. Pro Tools LE shared the same interface of Pro Tools HD but had a smaller track count (24 tracks with Pro Tools 5, extended to 32 tracks with Pro Tools 6 and 48 tracks with Pro Tools 8) and supported a maximum sample rate of 96 kHz (depending on the interface used). Some advanced software features, such as Automatic Delay Compensation, surround mixing, multi-track Beat Detective, OMF/AAF support, and SMPTE Timecode , were omitted. Some of them, as well as support for 48 tracks/96 voices (extended to 64 tracks/128 voices with Pro Tools 8) and additional plug-ins, were made available through an expansion package called "Music Production Toolkit". The "Complete Production Toolkit", introduced with Pro Tools 8, added support for surround mixing and 128 tracks (while

4018-405: The introduction of surround sound mixing and multichannel plug-ins—up to the 7.1 format —with Pro Tools TDM 5.1 in 2001. The migration from traditional, tape-based analog studio technology to the Pro Tools platform took place within the industry: Ricky Martin 's " Livin' la Vida Loca " (1999) was the first Billboard Hot 100 number-one single to be recorded, edited, and mixed entirely within

4100-492: The larger number of tracks was achieved with a SCSI expansion card developed by Grey Matter Response, called System Accelerator. In the same year, Digidesign announced that it merged into the American multimedia company Avid , developer of the digital video editing platform Media Composer and one of Digidesign's major customers (25% of Sound Accelerator and Audiomedia cards produced was being bought by Avid). The operation

4182-597: The mid-1970s and is vested in the company that makes the software, not the employees or contractors who wrote it. The use of most software is governed by an agreement ( software license ) between the copyright holder and the user. Proprietary software is usually sold under a restrictive license that limits copying and reuse (often enforced with tools such as digital rights management (DRM)). Open-source licenses , in contrast, allow free use and redistribution of software with few conditions. Most open-source licenses used for software require that modifications be released under

The process of developing software involves several stages. The stages include software design , programming , testing , release , and maintenance . Software quality assurance and security are critical aspects of software development, as bugs and security vulnerabilities can lead to system failures and security breaches. Additionally, legal issues such as software licenses and intellectual property rights play

4346-472: The operating system) can take this saved file and execute it as a process on the computer hardware. Some programming languages use an interpreter instead of a compiler. An interpreter converts the program into machine code at run time , which makes them 10 to 100 times slower than compiled programming languages. Software is often released with the knowledge that it is incomplete or contains bugs. Purchasers knowingly buy it in this state, which has led to

4428-580: The pair thought to design a more functional and flexible solution which could take advantage of a graphical interface. In collaboration with E-Mu , they developed a Mac-based visual sample editing system for the Emulator II keyboard, called Sound Designer, released under the Digidesign brand and inspired by the interface of the Fairlight CMI . This system, the first ancestor of Pro Tools,

4510-632: The pair were creating and selling drum sound chips under their Digidrums label. Sound Designer was originally designed to edit sounds for sampling synthesizers like the Prophet 2000, Ensoniq Mirage, Akai s900 and the E-MU Emulator sampling keyboard. Sounds would be sampled into the synth and transferred onto the Mac. Here, the user could manipulate the sample's sound—EQ, amplitude, etc.; truncate to save memory; or set loop points; and then transfer back into

4592-618: The physical world may also be part of the requirements for a software patent to be held valid. Software patents have been historically controversial . Before the 1998 case State Street Bank & Trust Co. v. Signature Financial Group, Inc. , software patents were generally not recognized in the United States. In that case, the Supreme Court decided that business processes could be patented. Patent applications are complex and costly, and lawsuits involving patents can drive up

4674-623: The playback of 16 tracks. A dedicated SCSI card was still required to provide the required bandwidth to support multiple-card systems. Along with Pro Tools III, Digidesign launched the 888 interface, with eight channels of analog and digital I/O, and the cheaper 882 interface. The Session 8 system included a control surface with eight faders. A series of TDM plug-ins were bundled with the software, including dynamics processing , EQ, delay, modulation, and reverb . In 1996, following Apple's decision to drop NuBus in favor of PCI bus , Digidesign added PCI support with Pro Tools 3.21. The PCI version of

4756-524: The possibility of integrating their renamed 'Sound Tools' software into the Emulator III keyboard released in 1987; however, E-MU rejected this option, and Gotcher and Brooks went on to start DigiDrums. Sound Tools was debuted at the NAMM Show on January 20, 1989. At this stage, Sound Tools was a simple computer-based stereo audio editor. Although the software had the possibility to do far more, it

4838-505: The previous 24-bit and 48-bit fixed-point resolution of the TDM engine), thus improving dynamic range performance. Signal processing could be run on the embedded DSP, providing additional computational power and enabling near zero-latency for DSP-reliant plug-ins. Two FPGA chips handled track playback, monitoring, and internal routing, providing a lower round trip latency. A second line of PCIe cards, called HD Native, provided low latency with

4920-628: The printed source code to a 68000 assembly language interrupt-driven MIDI driver, was distributed through Macintosh MIDI interface manufacturer Assimilation, which manufactured the first MIDI interface for the Mac in 1985. Starting from the same year, a dial-up service provided by Beaverton Digital Systems, called MacMusic, allowed Sound Designer users to download and install the entire Emulator II sound library to other less expensive samplers: sample libraries could be shared across different manufacturers platforms without copyright infringement. MacMusic contributed to Sound Designer's success by leveraging both

5002-408: The release. Over time, the level of maintenance becomes increasingly restricted before being cut off entirely when the product is withdrawn from the market. As software ages , it becomes known as legacy software and can remain in use for decades, even if there is no one left who knows how to fix it. Over the lifetime of the product, software maintenance is estimated to comprise 75 percent or more of

Patents give an inventor an exclusive, time-limited license for a novel product or process. Ideas about what software could accomplish are not protected by law and concrete implementations are instead covered by copyright law . In some countries, a requirement for the claimed invention to have an effect on

5166-415: The sample rate doubled (128 voices at 88.2/96 kHz, 64 voices at 176.4/192 kHz). Up to three HDX cards could be installed on a single system for a maximum of 768/384/192 total voices and for increased processing power. On Native systems, voice count was limited to 96/48/24 voices with the standard version of Pro Tools and 256/128/64 voices with Pro Tools HD software. With Pro Tools 10, Avid deployed

5248-432: The software (Pro Tools 6) with new features and a redesigned GUI, developed for OS X and Windows XP . Two HD interfaces could be linked together for increased I/O through a proprietary connection. The base system was selling for US$ 12,000, while the full system was selling for US$ 20,000. Both HD Core and Process cards mounted nine Motorola 56361 chips running at 100 MHz, each providing 25% more processing power than

5330-414: The software was still limited by their performance; densely edited tracks could cause glitches. However, the rapidly evolving computer technology allowed developments towards a multi-track sequencer. The core engine and much of the user interface of the first iteration of Pro Tools was based on Deck. The software, published in 1990, was the first multi-track digital recorder based on a personal computer. It

5412-483: The software. Any audio device could be used through Core Audio on macOS or the ASIO driver on a Windows. Core Audio allowed device aggregation, enabling using of more than one interface simultaneously. Some Pro Tools HD software features, such as automatic plug-in delay compensation, OMF/AAF file import, Timecode ruler, and multi-track Beat Detective, were included in the standard version of Pro Tools 9. When operating on

5494-544: The synth for playback. The software was originally written for editing drum samples and then for burning new chips for the LinnDrum era drum machines. The SDII (Sound Designer II, sometimes seen abbreviated as SD2) is a monophonic/stereophonic audio file format, originally developed by Digidesign for their Macintosh-based recording/editing products. It is the successor to the original monophonic Sound Designer I audio file format. Gotcher and Brooks discussed with E-MU Systems

5576-487: The system was still limited to 128 voices). With the acquisition of M-Audio in 2004–2005, Digidesign released a specific variant of Pro Tools, called M-Powered , which was equivalent to Pro Tools LE and could be run with M-Audio interfaces. The Pro Tools LE/ M-Powered line was discontinued with the release of Pro Tools 9. Pro Tools 9, released in November 2010, dropped the requirement of proprietary hardware to run

The service used 2400- baud modems and 100 MB of disk space with Red Ryder host on a 1 MB Macintosh Plus . With the release of Apple Macintosh II in 1987, which provided card slots, a hard disk, and more capable memory, Brooks and Gotcher saw the possibility to evolve Sound Designer into

5822-494: The updated Pro Tools | 24 MIX system provided three times more DSP power with the MIX Core DSP cards. MIXplus systems combined a MIX Core with a MIX Farm, obtaining a performance increase of 700% compared to a Pro Tools | 24 system. Pro Tools 5 saw two substantial software developments: extended MIDI functionality and integration in 1999 (an editable piano-roll view in the editor; MIDI automation, quantize and transpose) and

5904-557: Was also possible. A two-channel digital interface (DAT-I/O) with AES/EBU and S/PDIF connections was made available later in 1989, while the Pro I/O interface came out in 1990 with 18-bit converters. The file format used by Sound Designer II (SDII) became eventually a standard for digital audio file exchange until the WAV file format took over a decade later. Since audio streaming and non-destructive editing were performed on hard drives,

5986-441: Was developed by OSC, a small San Francisco company founded the same year, in conjunction with Digidesign and ran on Digidesign's hardware. Deck could run four audio tracks with automation; MIDI sequencing was possible during playback and record, and one effect combination could be assigned to each audio track (2-band parametric equalizer, 1-band EQ with delay , 1-band EQ with chorus , delay with chorus). The first Pro Tools system

6068-573: Was distributed with Pro Tools LE, a specific version of the software without DSP support, limited to 24 mixing tracks. Following the launch of Mac OS X operating system in 2001, Digidesign made a substantial redesign of Pro Tools hardware and software. Pro Tools | HD was launched in 2002, replacing the Pro Tools | 24 system and relying on a new range of DSP cards (HD Core and HD Process, replacing MIX Core and MIX Farm), new interfaces running at up to 192 kHz or 96 kHz sample rates (HD 192 and 96, replacing 888 and 882), along with an updated version of

6150-440: Was extended to 192/96/36 tracks at 48/96/192 kHz sample rates. The use of PCI Express connection reduced round-trip delay time , while DSP audio processing allowed the use of smaller hardware buffer sizes during recording, assuring stable performance with extremely low latency. Pro Tools, offering a solid and reliable alternative to analog recording and mixing, eventually became a standard in professional studios throughout

6232-513: Was finalized in 1995. With a redesigned Disk I/O card, Pro Tools III was able to provide 16 tracks with a single NuBus card; the system could be expanded using TDM to up to three Disk I/O cards, achieving 48 tracks. DSP Farm cards were introduced to increase the processing power needed for a more extensive real-time audio processing; each card was equipped with three Motorola 56001 chips running at 40 MHz. Multiple DSP cards could be added for additional processing power; each card could handle

6314-420: Was launched on June 5, 1991. It was based on an adapted version of Deck (ProDeck) along with Digidesign's new editing software, ProEdit, created by Mark Jeffery; Sound Designer II was still supplied for two-channel editing. Pro Tools relied on Digidesign's Audiomedia card, mounting one Motorola 56001 processor with a clock rate of 22.58 MHz and offering two analog and two digital channels of I/O , and on

6396-512: Was limited by the hard drive technology, which was used to stream the audio and allow for the non-destructive editing that Sound Tools offered. Independent public radio producers soon discovered the power and economy of Sound Tools as an alternative to traditional analog tape, sparking the transition to digital program production and distribution in radio. The first version of Pro Tools was launched in 1991, offering four tracks and selling for US$ 6,000. Digidesign continued to improve Pro Tools, adding

6478-520: Was quite popular at that time, although it was limited to its built-in samples. They started selling the upgrade chips one year later under their new Digidrums label. Five different upgrade chips were available, offering different alternate drum styles. The chips, easily switchable with the original ones, enjoyed remarkable success between the Drumulator users, selling 60,000 units overall. When Apple released its first Macintosh computer in 1984,

6560-478: Was released in 1985 at the price of US$ 995. Brooks and Gotcher rapidly ported Sound Designer to many other sampling keyboards, such as E-mu Emax , Akai S900 , Sequential Prophet 2000 , Korg DSS-1 , and Ensoniq Mirage . Thanks to the universal file specification subsequently developed by Brooks with version 1.5, Sound Designer files could be transferred via MIDI between sampling keyboards of different manufacturers. This universal file specification, along with

6642-401: Was simultaneous with the compilers needed to translate them automatically into machine code. Most programs do not contain all the resources needed to run them and rely on external libraries . Part of the compiler's function is to link these files in such a way that the program can be executed by the hardware. Once compiled, the program can be saved as an object file and the loader (part of

6724-636: Was supplied with its first built-in virtual instruments library, the AIR Creative Collection, as well as with some new plug-ins, to make it more appealing for music production. An expansion was also available, called AIR Complete Collection. In October 2011, Avid introduced Pro Tools 10 and a new series of DSP PCIe cards named HDX. Each card mounted 18 DSP processors, manufactured by Texas Instruments, allowing an increased computational precision ( 32-bit floating-point resolution for audio processing and 64-bit floating-point summing, versus
