A digital audio workstation (DAW) is a system designed to record, edit and play back digital audio. A sound editor is a creative professional responsible for selecting and assembling Sound recordings in preparation for the final Sound mixing or Mastering A key feature of DAWs is the ability to freely manipulate recorded sounds, much like a word processor manipulates typed words.

The term "DAW" simply refers to a general combination of audio multitrack software and high-quality audio hardware — the latter being a specialized audio converter unit which performs some variety of both analog-to-digital (ADC) and digital-to-analog (DAC) conversion. In Signal processing, an audio converter or digital audio converter is a type of Electronic hardware technology which converts an analog An analog-to-digital converter (abbreviated ADC, A/D or A to D) is an electronic integrated circuit which converts continuous signals to In Electronics, a digital-to-analog converter ( DAC or D-to-A) is a device for converting a digital (usually binary code to an Analog signal For example, a digital 8-track system could have eight discrete inputs, and a certain number of outputs — perhaps only stereo output for playback and monitoring. Stereophonic sound, commonly called stereo, is the reproduction of Sound, using two or more independent audio channels through a Symmetrical

Because "tracks" are symbolic in the digital medium, multitrack systems could have only a pair of mono inputs and outputs — the discrete audio inputs and outputs provide for simultaneous multitracking capability, whereas limited inputs require audio mixing or later overdubbing. Audio mixing is the process by which a multitude of sound sources are combined into one or more channels Overdubbing (the process of making an overdub, or overdubs is a technique used by Recording studios to add a supplementary recorded sound to a previously recorded

A professional DAC performs the same function as a common sound card, but is generally an external and sometimes rackmounted unit which offers the advantage of far less noise, higher recorded resolution, and better dynamic range, when compared with its consumer cousin. A sound card (also known as an audio card is a Computer Expansion card that facilitates the input and output of audio signals to/from a computer under is a one volume manga created by Tsutomu Nihei as a prequel to his ten-volume work Blame!. Dynamic range is a term used frequently in numerous fields to describe the Ratio between the smallest and largest possible values of a changeable quantity such as in Sound

While almost any home computer with multitrack and editing software can function somewhat as a DAW, the term generally refers to computer systems which have high-quality external ADC-DAC hardware, and some form of audio software; some of which is commercial proprietary software such as Logic Pro, Pro Tools, Samplitude, Cubase, SONAR, ACID Pro, FL Studio (formerly Fruityloops), Ableton Live, Tracktion or Digital Performer, some of which is free software such as Audacity and Ardour.

DAWs generally come in two varieties:

Computer-based DAW

consist of three components: a computer, an ADC-DAC, and digital audio editor software. A computer is a Machine that manipulates data according to a list of instructions. In Signal processing, an audio converter or digital audio converter is a type of Electronic hardware technology which converts an analog A digital audio editor is a computer application for Audio editing, i The computer acts as a host for the sound card and software and provides processing power for audio editing. The sound card acts as an audio interface, typically converting analog audio signals into digital form, and may also assist in processing audio. The software controls the two hardware components and provides a user interface to allow for recording and editing. Many radio stations in the U. S. prefer using computer-based DAWs over integrated DAWs.

Integrated DAW

consist of a mixing console, control surface, and digital interface in one device. In professional audio, a mixing console, or audio mixer, also called a sound board or soundboard, is an electronic device for combining Integrated DAWs were more popular before personal computers became powerful enough to run DAW software. As computer power increased and price decreased, the popularity of the costly integrated systems dropped. However, systems such as the Orban Audicy once flourished in the radio and television markets. Orban, also known as Urban, was a Hungarian / Romanian engineer Today, some systems still offer computerless arranging and recording features with a full graphical user interface, such as the Roland MV-8000, Roland MV-8800 and recent Mackie HDR-series hard disk recorders. is a Japanese manufacturer of Electronic musical instruments electronic equipment and Software. is a Japanese manufacturer of Electronic musical instruments electronic equipment and Software. Mackie is a brand of the United States based company LOUD Technologies.

History

The first digital audio workstation was developed by Soundstream in the late 1970s, using a Digital Equipment Corporation PDP-11 minicomputer running a custom software package called "DAP" (for Digital Audio Processor) for digital audio editing and audio effects such as crossfades. Soundstream Inc was founded in 1975 in Salt Lake City Utah by Dr Digital Equipment Corporation was a pioneering American company in the Computer industry The PDP-11 was a series of 16-bit Minicomputers sold by Digital Equipment Corp A minicomputer (colloquially mini) is a class of multi-user Computers that lies in the middle range of the computing spectrum in between the largest Multi-user A storage oscilloscope that was connected to the minicomputer acted as the audio waveform display. An oscilloscope (commonly abbreviated to scope or O-scope) is a type of Electronic test equipment that allows signal Voltages to be viewed Edits were made by typing in three-letter commands on a separate computer terminal, using the waveform display on the storage oscillioscope as a reference. A computer terminal is an electronic or electromechanical hardware device that is used for entering data into and displaying data from a Computer or a Computing

Audio on the system was stored on disk pack drives, with the audio transferred onto the drives from Soundstream's proprietary digital audio tape recorders using a Unibus tape-to-disk interface also of the company's own design. Disk pack is a layered grouping of Hard disk platters (circular rigid discs coated with a Magnetic Data storage surface The Unibus was the earliest of several bus technologies used with PDP-11 and early VAX systems manufactured by the Digital Equipment Corporation Soundstream also developed a digital-to-analog interface for this system for interfacing to conventional analog tape recorders as well.

In 1981, recording engineer Roger Nichols built a digital audio workstation of his own design, using a S-100 bus-based computer with a Micropolis 8" form factor 32 MB hard disk used for storage of digital audio data. Roger Nichols is a recording engineer best-known for his work with the group Steely Dan. The S-100 bus, IEEE696 -1983 (withdrawn, was an early Computer bus designed in 1974 as a part of the Altair 8800, generally considered today Micropolis Corporation was a disk drive company located in Chatsworth California. It interfaced digitally to a 3M multi-track digital audio tape recorder in his studio, and was used to edit audio from the recorder. 3M Company ( formerly Minnesota Mining and Manufacturing Company until 2002 is an American multinational conglomerate corporation with a worldwide Nichols' system was used during the recording and production of Donald Fagen's 1982 album, The Nightfly. Donald Jay Fagen (born January 10, 1948 in Passaic New Jersey) is an American Musician and Songwriter. Year 1982 ( MCMLXXXII) was a Common year starting on Friday (link displays the 1982 Gregorian calendar) The Nightfly is the first solo Album by Steely Dan co-founder Donald Fagen, released in 1982.

At the late 1980s, consumer level computers such as the Apple Macintosh or the Commodore Amiga started to have enough power to handle the task of digital audio editing. Macintosh, commonly nicknamed Mac is a Brand name which covers several lines of Personal computers designed developed and marketed by Apple Inc The Amiga is a family of Personal computers originally developed by Amiga Corporation. Macromedia's Soundedit was the first audio editing software to appear for the Macintosh in 1986, but the concept was made popular by a company called Digidesign, who in 1987 introduced one of the first hardware & software packages for a personal computer for editing audio. Macromedia was a North American graphics and Web development Software house headquartered in San Francisco, California producing such products Digidesign is an American Digital audio technology company It was founded in 1984 by Peter Gotcher and Evan Brooks The software was originally called Sound Tools and it was later renamed to Pro Tools I. Sound Tools was the first Digital audio workstation released by Digidesign in the late 1980s This was the predecessor to the now-industry standard Pro Tools system. Pro Tools is a Digital Audio Workstation platform for Mac OS and Microsoft Windows operating systems developed and manufactured by Digidesign Many major recording studios finally "went digital" because Digidesign had modeled its Pro Tools software after the traditional method and signal flow present in almost all analog recording devices. A recording studio is a facility for sound recording. Ideally the space is specially designed by an acoustician to achieve the desired acoustic properties (sound Digidesign is an American Digital audio technology company It was founded in 1984 by Peter Gotcher and Evan Brooks Pro Tools is a Digital Audio Workstation platform for Mac OS and Microsoft Windows operating systems developed and manufactured by Digidesign

In 1990 a company called OSC allong with Digidesign technicians launch a 4 track editing-recorder software called DECK II, (only $399,95), employed in The Residents' "Freakshow" LP. The Residents is an American Avant-garde music and Visual arts collective who have created over sixty albums created numerous musical short films

Development

Musicians and composers long had a desire to integrate stereos, turntables, recording equipment, MIDI keyboards and even electric guitars with computers. A musician is a person who plays or writes Music. Musicians can be classified by their roles in creating or performing music An instrumentalist plays a The phonograph, or gramophone, was the most common device for playing recorded Sound from the 1870s through the 1980s MIDI ( Musical Instrument Digital Interface, ˈmɪdi is an industry-standard protocol that enables Electronic musical instruments Computers An electric guitar is a type of Guitar that uses pickups to convert the vibration of its steel-cored strings into an electrical current which is made louder Serious computer-based composition tools began to appear with the Atari ST and Amiga computer systems. The Atari ST is a home / Personal computer that was commercially available from 1985 to the early 1990s The Amiga is a family of Personal computers originally developed by Amiga Corporation. Enthusiasts continued to seek more integrated, easier-to-use and higher-performance tools for audio creation tasks. Many current DAWs even support integration with video streams allowing full A/V production.

Common functionality of computer-based DAWs

As software systems, DAWs could be designed with any user interface, but generally they are based on a multitrack tape recorder metaphor, making it easier for recording engineers and musicians already familiar with using tape records to become familiar with the new systems. Digital audio uses Digital signals for Sound reproduction. This includes analog-to-digital conversion, digital-to-analog conversion, storage A digital audio editor is a computer application for Audio editing, i Steinberg 's Virtual Studio Technology (VST is an interface for integrating software Audio Synthesizer and effect Plugins with Multitrack recording ('multitracking' or just 'tracking' for short is a method of Sound recording that allows for the separate recording of multiple sound sources to create Audio engineering is a part of audio science dealing with the recording and reproduction of Sound through mechanical and electronic means A musician is a person who plays or writes Music. Musicians can be classified by their roles in creating or performing music An instrumentalist plays a Therefore, computer-based DAWs tend to have a standard layout which includes transport controls (play, rewind, record, etc. ), track controls and/or a mixer, and a waveform display. waveformogg|right|a sine square and sawtooth wave at 440 hz]] Waveform means the shape and form of a signal such as a Wave moving in a solid liquid or gaseous In single-track DAWs, only one (mono or stereo form) sound is displayed at a time. Monaural (often shortened to mono) sound reproduction is single-channel Stereophonic sound, commonly called stereo, is the reproduction of Sound, using two or more independent audio channels through a Symmetrical

Multitrack DAWs support operations on multiple tracks at once. Like a mixing console, each track typically has controls that allow the user to adjust the overall volume and stereo balance (pan) of the sound on each track. In professional audio, a mixing console, or audio mixer, also called a sound board or soundboard, is an electronic device for combining Loudness is the quality of a Sound that is the primary psychological correlate of physical strength (amplitude In a traditional recording studio additional processing is physically plugged in to the audio signal path, a DAW, however, uses software plugins to process the sound on a track.

While DAWs are capable of mimicking the functions of a traditional recording studio, there are areas where they excel, and in some cases they can do things that are impossible without a DAW.

Perhaps the most significant feature available on a DAW that is not available in analogue recording (some other forms of digital recording do have this) is the ability to 'undo' a previous action, which makes it much easier to avoid accidentally erasing or recording over a previous recording.

Commonly DAWs feature some form of automation, commonly performed through "envelope points. " Each dot represents one envelope point. By creating and adjusting multiple points along a waveform or control events, the user can specify parameters of the output over time (e. g. , volume or pan).

Commercial systems

There are many DAW programs that provide recording and editing audio, recording and editing MIDI data, sound processing and synthesis. Commercial systems are often designed to run on Macintosh or Windows operating systems and are usually developed for profit. An operating system (commonly abbreviated OS and O/S) is the software component of a Computer system that is responsible for the management and coordination

Consolidation and compatibility within commercial spaces, along with the early adaptation by many major recording studios has bolstered the user base and reputation of Digidesign's Pro Tools for recording and editing audio.

There are many free and open-source programs that can facilitate a DAW. Free software or software libre is Software that can be used studied and modified without restriction and which can be copied and redistributed in modified or unmodified Open source software (OSS began as a marketing campaign for Free software. These are often designed to run on a variety of operating systems and are usually developed non-commercially. An operating system (commonly abbreviated OS and O/S) is the software component of a Computer system that is responsible for the management and coordination The LADSPA plugin architecture, the JACK API and the ALSA soundcard driver represent the 'cutting-edge' in free and open source DAW development for professional audio production. A sound card (also known as an audio card is a Computer Expansion card that facilitates the input and output of audio signals to/from a computer under

The development of digital audio for Linux and BSD fostered technologies such as ALSA, which drives audio hardware, and JACK or aRts (audio Real-time synthesizer). Linux (commonly pronounced ˈlɪnəks Advanced Linux Sound Architecture (known by the Acronym ALSA) is a Linux kernel component intended to replace the original Open Sound System The JACK Audio Connection Kit or JACK is a Sound server daemon that provides Low latency connections between so-called jackified aRts, which stands for a nalog R eal t ime s ynthesizer is an audio framework that is no longer under development JACK allows any JACK-aware audio software to connect to any other audio software running on the system, such as connecting an ALSA or OSS driven soundcard to a mixing and editing front-end, like Audacity or Rosegarden. The Open Sound System (OSS is a standard interface for making and capturing sound in Unix operating systems In this way, JACK acts as a virtual audio patch bay, and it can be configured to use a computer's resources in real time, with dedicated memory, and with various options that minimize the DAW's latency. A patch panel or patch bay or jackfield is a panel typically Rackmounted that houses Cable connections In computer systems design a flat memory model refers to a linear addressing Paradigm, such that the CPU can directly (and sequentially address all of the available Low latency allows human-unnoticeable delays between an Input being processed and the corresponding Output providing Real time characteristics This kind of abstraction and configuration allows DJs to use multiple programs for editing and synthesizing audio streams, or multitasking and duplexing, without the need for analogue conversion, or asynchronous saving and reloading files, and ensures a high level of audio fidelity. A disc jockey (also known as DJ or deejay) is a person who selects and plays recorded music for an audience Asynchrony, in the general meaning is the state of not being synchronized. High fidelity or hi-fi reproduction is a term used by home stereo listeners and home audio enthusiasts ( Audiophiles to refer to high-quality reproduction Linux and BSD also support the aRts platform, distributed with the K desktop environment, KDE. Linux (commonly pronounced ˈlɪnəks aRts, which stands for a nalog R eal t ime s ynthesizer is an audio framework that is no longer under development KDE ( K Desktop Environment) (ˌkeɪdiːˈiː is a Free software project which aims to be a powerful system for an easy-to-use Desktop environment.

SoundFont is a Brand name that collectively refers to a File format and associated technology designed to bridge the gap between recorded and synthesized Such virtualization allows users to expand the traditional limitations of ADC-DAC hardware.

The Linux Audio Development mailing list, LAD, is a major driving force in developing standards, such as the LADSPA plugin architecture, for free and open systems. Standardization (or standardisation) is the process of developing and agreeing upon technical standards. LADSPA is an Acronym for Linux Audio Developers Simple Plugin API. The VST plugin standard is supported as an option by some such programs but is generally implemented as a separate plugin, not a built-in option, due to Steinberg's licensing scheme. VST is a Three-letter abbreviation with multiple meanings Vancouver School of Theology - A theological graduate school located in the University Steinberg is a German Musical equipment and Software company It mainly produces MIDI Music sequencer software Among others, the creators of Audacity provide an optional, somewhat minimalist, VST-to-LADSPA bridge plugin for their software, but it is a separate download.
