A digital audio workstation ( DAW ) is an electronic device or application software used to record, edit and produce audio files. DAW comes in a variety of configurations from one software program on a laptop, to a stand-alone stand-alone unit, down to a very complicated configuration of many components controlled by a central computer. Regardless of configuration, modern DAWs have a central interface that allows users to change and mix multiple recordings and tracks into the resulting end.
DAW is used for the production and recording of music, songs, speeches, radio, television, soundtracks, podcasts, sound effects and almost any other situation where complex audio recording is required.

History
Early attempts at digital audio workstations in the 1970s and 1980s faced limitations such as high storage prices, and much slower processing and disk speeds at the time. In 1978, Soundstream (which had made one of the first commercially available digital audio recorders in 1977) built what could be considered the first digital audio workstation to use some of the latest computer hardware at the time. The Digital Editing System , as called Soundstream, consists of a mini DEC PDP-11/60 computer running a software package called DAP (Digital Audio Processor), a 14-inch hard disk drive Braegen , a storage oscilloscope to display the audio waveform for editing, and the video display terminal for controlling the system. Interface cards connected to the Unibus PDP-11 ( Digital Audio Interface , or DAI slot) provide analog and digital audio input and output to interact with the Soundstream digital recorder and analog cassette recorder conventional. The DAP software can make edits to the recorded audio on the system hard disk and gives effects like crossfades.
In the late 1980s, a number of consumer-level computers such as MSX (Yamaha CX5M), Apple Macintosh, Atari ST and Commodore Amiga began to have sufficient power to handle digital audio editing. Engineers use Macromedia's Soundedit, with Microdeal's Replay Professional and Digidesign's "Sound Tools" and "Sound Designer" to edit audio samples for keyboard sampling such as E-mu Emulator II and Akai S900. Soon, people started using it to edit the audio of two simple songs and master the CD. In 1989, Sonic Solutions released the first professional nonlinear audio editing system (48 kHz on 24 bit). The Mac IIfx Mac-based Sonic system, based on previous research at George Lucas' Sprocket Systems, features a full CD premastering, with integrated control of digital digital U-matic tape digital standard audio editors. This combination of audio software and hardware is the earliest commercial example of what is now called Digital Audio Workstation or DAW. In 1994, a California company called OSC produced a 4-track edit-record application called DECK that runs on the Digidesign hardware system, used in the production of The Residents' "Freakshow" [LP].
Many major recording studios eventually "go digital" after Digidesign introduced its Pro Tools software, modeled after traditional methods and signal flow across most analog recording devices. Currently, most Apple-based DAW Macs (e.g., Pro Tools, Dyaxis Studs, Sonic Solutions). Around 1992, the first Windows-based DAW began emerging from companies such as IQS Innovative Quality Software (now SAWStudio), Digital Soundscape Technology, SADiE, Echo Digital Audio, and Spectral Synthesis. All systems at this point use special hardware for their audio processing.
In 1993, the German company Steinberg released Cubase Audio in Atari Falcon 030. This version brought DSP with a built-in effect with 8-track audio recording & amp; playback using only native hardware. The first Windows-based software product, introduced in 1993, was Samplitude Studio (which existed in 1992 as an audio editor for Commodore Amiga).
In 1996, Steinberg introduced the VST Cubase, which can record and play up to 32 digital audio tracks on Apple Macintosh without the need for external DSP hardware. Cubase not only modeled ribbon-like interfaces for recording and editing, but also modeled all the mixing tables and rack effects common in analog studios. It revolutionized the DAW world, both in features and price tags, and was quickly replicated by most other contemporary DAW systems.

DAW Integrated
DAW integrated consists of mixing consoles, control surfaces, audio converters, and data storage in a single device. The integrated DAW is more popular before the commonly available personal computers become powerful enough to run DAW software. As computer power and speed increase and prices decrease, the popularity of expensive integrated systems with console automation decreases. Systems such as Orban Audicy become standard production equipment in radio and television stations.
DAW Software
"DAW" can only refer to the software itself, but traditionally, computer-based DAW has four basic components: computer, sound card or audio interface, digital audio editor software, and at least one input device to add or modify data. It can be as simple as a mouse (if no external instrument is used) or as sophisticated piano-style MIDI controller keyboard or automatic fader board to mix song volume.
The computer acts as the host for the sound/audio card interface, while the software provides the interface and functionality for editing audio. The sound card/external audio interface usually converts the analog audio signal to digital form, and returns digital to analog audio when playing it again; it can also help further processing of audio. The software controls all associated hardware components and provides a user interface to enable recording, editing, and playback.
Computer-based DAW has extensive recording, editing, and playback capabilities (some even have video-related features). For example, musically, they can provide almost unlimited improvements to additional tracks for recording, polyphony, and virtual synthesizers or sample-based instruments to use for recording music. A DAW with sample section string emulator can be used to add a "bearing" companion string to a pop song. DAWs can also provide various effects, such as reverb, to enhance or change the sound itself.
DAWs-based smartphones are simple, called Mobile Audio Workstations (MAWs), used (for example) by journalists for recording and editing on location. Many are sold in app stores like iOS App Store or Google Play.
General functions
As a software system, DAW is designed with many user interfaces, but generally they are based on a multitrack cassette recorder metaphor, making it easier for recording of familiar engineers and musicians by using a tape recorder to become familiar with the new system. Therefore, computer-based DAWs tend to have a standard layout that includes transport controls (rotate, rewind, record, etc.), Trajectory control and mixer, and waveform display. Single-track DAWs only show one (mono or stereo form) track at a time. The term "track" is still used with DAW, although there is no physical track as it is in the era of tape-based recordings.
Multitrack DAWs support operations on multiple tracks at once. Like the mixing console, each track typically has a control that allows the user to adjust the overall volume, balance and balance of the stereo (pan) sound of each song. In a traditional recording studio additional rackmount processing equipment is physically plugged into the audio signal path to add reverb, compression, etc. However, DAW can also route software or use audio plug-ins (for example, VST plugins) to process sounds on the track.
DAW is able to perform many of the same functions as traditional studio-based tape settings, and in recent years almost completely replaced it. Sophisticated modern recording studio may have several DAW types in it and it is not uncommon for a voice engineer and/or musician to travel with portable DAW-based laptops, although interoperability between DAW is poor.
Perhaps the most significant feature available from DAW that is not available on analog recordings is the ability to 'undo' previous actions, using commands similar to the "undo" button in word processing software. Undo makes it easier to avoid accidentally deleting or recording permanently on previous recordings. If an error or unwanted change is made, the undo command is used to easily restore the changed data to a previous state. Cut, Copy, Paste, and Undo are commonly known computer commands and are usually available in DAW in some form. More general functions include modification of several factors about sound. These include waveform, pitch, tempo, and filtering.
Usually DAWs feature some form of automation, often done via "envelopes". Envelopes are segment-based interactive graphs or procedural-based curves. Lines and curves of the automation graph join or consist of adjustable points. By creating and adjusting multiple points along the waveform or control event, the user can define the output parameters over time (eg, volume or pan). Automation data can also be directly derived from human movements recorded by the control or control surfaces. MIDI is a common data protocol used to transfer such gestures to DAW.
MIDI recording, editing and playback are increasingly incorporated into modern DAWs of all types, such as syncing with other audio and/or video equipment.
Plug-in
There are many software plugins for DAW software, each coming with its own unique function, thereby expanding the overall sound and manipulation possible. Some functions of this plugin include digital effects units that can modify the signal with distortion, resonator, equalizer, synthesizer, compressor, chorus, virtual amp, limiter, phaser, and flangers. Each has its own form of manipulating sound waves, tones, tones, and simple sound speeds and turning them into something different. To achieve a more distinctive sound, some plugins can be used in layers, and more automatically to manipulate the original sound and shaping it into a completely new sample.

Free and open software
There are many free and open source software programs that can facilitate DAW. These are often designed to run on a variety of operating systems and are typically developed on a non-commercial basis.
The development of digital audio for Linux and BSD fosters technologies like ALSA, which drive audio hardware, and JACK. JACK allows JACK-aware audio software to connect to other audio software running on the system, such as connecting ALSA or OSS soundcards to mixing and front-end editing, such as Ardor or Rosegarden. In this way, JACK functions as a virtual audio storage, and can be configured to use real-time computer resources, with custom memory, and with options that minimize DAW latency. This type of abstraction and configuration allows DJs to use multiple programs to edit and synthesize audio streams, or multitasking and duplexing, without the need for analog conversion, or asynchronous storage and reloading files, and ensuring high levels of audio fidelity.
- Audacity is a free, open source, digital audio editor that runs on Microsoft Windows, but also on OS X, Linux and other Unix-like systems (including OpenSolaris and TrueOS); this is very popular in the podcast community, and also has many followers amongst the blind because of its keyboard interface. However, it lacks MIDI support, concentrating more on sound manipulation and management rather than separate events and sequences.
- Rosegarden is a multi-feature audio app that includes an audio mixing plugin, notation editor, and MIDI. The MusE Sequencer is the same audio application feature that includes an audio mixer and MIDI sequencer.
Other open-source programs include virtual synthesizers and MIDI controllers, such as those provided by FluidSynth and TiMidity. Both can load SoundFonts to expand the sounds and instruments available for synthesis and expand the ports and channels available for synthesizers. Such virtualization allows users to expand the limitations of traditional ADC-DAC hardware.
Linux Audio Development Center (LAD) is the main driving force in developing standards, such as LADSPA plugin architecture, DSSI and LV2. The default Studio Virtual Plug (VST) plugin is supported as an option by some programs, but is generally applied as a separate plugin, not a default option, due to the Steinberg license scheme. Among other things, Audacity creators provide an optional, somewhat minimalist, VST-to-LADSPA bridge plugin for their software, but this is a separate download.
Some DAW developers also offer their free DAW commercial version, with lower functionality. Examples include Pro Tools First and Studio One Prime.
