A digital audio workstation (DAW / d ɔː / ) is a computer program or device used to record, edit, and create audio files. These workstations can be simple, like a single program on a laptop, or more complex, such as a self-contained machine or a setup with many parts connected to a main computer. No matter how they are set up, most modern DAWs have a main screen or control panel that lets users combine and mix different recordings and tracks to make a finished audio project.
DAWs are used to create and record music, songs, speech, radio, television, movie soundtracks, podcasts, sound effects, and many other types of audio recordings.
History
Early digital audio workstations from the 1970s and 1980s had problems, such as the high cost of storage and the much slower speed of computers and disks at that time.
In 1978, Soundstream, which had created one of the first commercial digital audio tape recorders in 1977, built what is considered the first digital audio workstation. They used the most advanced computer hardware available at the time. The system, called the Digital Editing System by Soundstream, included a DEC PDP-11/60 minicomputer running custom software named DAP (Digital Audio Processor), a Braegen 14-inch hard disk drive, a storage oscilloscope to show audio waveforms for editing, and a video display terminal to control the system. Interface cards connected to the PDP-11’s Unibus slots (called the Digital Audio Interface or DAI) allowed the system to receive and send both analog and digital audio signals to Soundstream’s recorders and traditional analog tape recorders. The DAP software could edit audio stored on the hard disk and apply basic effects, such as crossfades.
By the late 1980s, personal computers like the Macintosh, Atari ST, and Amiga had enough power to handle digital audio editing. Engineers used software such as Macromedia’s Soundedit, Microdeal’s Replay Professional, and Digidesign’s Sound Tools and Sound Designer to edit audio samples for sampling keyboards like the E-mu Emulator II and the Akai S900. Soon, these tools were also used for simple two-track audio editing and mastering.
In 1989, Sonic Solutions released the first professional (48 kHz at 24-bit) disk-based non-linear audio editing system. The system, based on the Macintosh IIfx and research from George Lucas’ Sprocket Systems, included full CD premastering and integrated control of Sony’s industry-standard U-matic tape-based digital audio editor.
Many major recording studios began using digital audio after Digidesign introduced Pro Tools software in 1991. This software was modeled after the traditional methods and signal flow of analog recording devices. At this time, most digital audio workstations (DAWs) were based on Apple Mac computers (e.g., Pro Tools, Studer Dyaxis, Sonic Solutions). Around 1992, the first Windows-based DAWs appeared from companies like Innovative Quality Software (IQS, now SAWStudio), Soundscape Digital Technology, SADiE, Echo Digital Audio, and Spectral Synthesis. All these systems used special hardware for audio processing.
In 1992, Sunrize Industries released the AD516 soundcard for Amiga computers. This allowed up to 8 tracks of 16-bit 48 kHz direct-to-disk recording and playback using its Studio 16 software. It could also connect directly to Blue Ribbon Soundworks’ Bars & Pipes Pro MIDI software or NewTek’s Video Toaster, creating a complete package that combined MIDI sequencing, video synchronization, and non-linear hard disk recording.
In 1993, the German company Steinberg released Cubase Audio for the Atari Falcon 030. This version included built-in digital signal processing (DSP) effects and allowed 8-track audio recording and playback using only native hardware. The first Windows-based software-only DAW, introduced in 1993, was Samplitude (which had already existed in 1992 as an audio editor for the Commodore Amiga).
Hardware
An integrated DAW is a single device that includes tools for processing sound digitally, physical controls like buttons and knobs, devices that convert sound into digital data, and storage for saving files. These all-in-one systems were widely used when personal computers lacked the power to run DAW software. As computers became faster, stronger, and more affordable, people began choosing cheaper computer-based solutions instead of expensive integrated systems.
Software
A DAW can refer to the software itself, but traditionally, a computer-based DAW has four main parts: a computer, a sound card or audio interface, audio editing software, and at least one user input device for adding or changing data. This device might be as simple as a mouse and keyboard or as complex as a MIDI controller keyboard or mixing surface.
The computer connects to the sound card, while the software provides the tools for editing audio. The sound card changes analog audio signals into digital form and converts digital signals back to analog when playing them. It may also help process audio further. The software controls all connected hardware and offers a user interface for recording, editing, and playing back audio.
Computer-based DAWs have strong recording, editing, and playback features. They can support many tracks, allow multiple sounds to play at once (polyphony), and use virtual synthesizers or sample-based instruments for music. They also offer effects like reverb to change or improve sounds.
Simple DAWs on smartphones, called mobile audio workstations (MAWs), are used by journalists to record and edit audio on location.
DAWs are designed with many user interfaces, but most follow a layout similar to a multitrack tape recorder. This makes it easier for engineers and musicians familiar with tape recorders to learn DAWs. Computer-based DAWs usually include transport controls (play, rewind, record), track controls, a mixer, and a waveform display.
Single-track DAWs show only one track at a time (mono or stereo). Multitrack DAWs handle multiple tracks simultaneously. Like a mixing console, each track has controls to adjust volume, equalization, and stereo balance. In traditional studios, extra equipment is physically connected to add effects like reverb or compression. DAWs can also use software or plugins (such as VST plugins) to process audio.
One major advantage of DAWs over analog recording is the ability to undo a previous action, like the "undo" feature in word processing. This helps prevent accidental changes or deletions. Commands like cut, copy, paste, and undo are common in DAWs. Other functions include adjusting sound properties like wave shape, pitch, tempo, and filtering.
Many DAWs include mix automation using graphs with adjustable points. These graphs let users control parameters like volume or pan over time. Automation data can also come from gestures recorded by a control surface or MIDI controller.
MIDI recording, editing, and playback are now common in modern DAWs, along with synchronization with other audio or video tools.
There are many free and open-source DAWs that work on various operating systems. Examples include Ardour and LMMS.
In 1983, Personal Composer, created by Jim Miller for Yamaha, was a highlight at the NAMM Show. It ran on MS DOS 2.0 and included a MIDI sequencer, synth editor, and score editor. It was later released as Personal Composer System/2 in 1988.
In 1996, Steinberg updated Cubase, which originally started as a MIDI sequencer for the Atari ST in 1989. The new version could record and play back 32 tracks of digital audio on a Mac without external hardware. Cubase used VST technology to model mixing desks and effects racks from analog studios, revolutionizing DAWs.
Linux and BSD systems helped develop technologies like Advanced Linux Sound Architecture (ALSA) and JACK Audio Connection Kit. JACK allows audio software to connect to each other, acting like a virtual patch bay. This setup reduces latency and lets users multitask with audio programs without analog conversion.
The Linux Audio Development (LAD) mailing list helped create standards like LADSPA, DSSI, and LV2 plugins. Some programs support the VST plugin standard.
DAWs use many plugins with unique functions to expand sound possibilities. Plugins can generate or change sound, tone, pitch, and speed. Combining multiple plugins can create more complex effects.
Recent advances in artificial intelligence are influencing DAWs. A research paper from Georgia Tech introduced the term "Generative Audio Workstation (GAW)" to describe DAWs using AI. Examples include AIVA, WavTool, and Symphony V. AIVA uses AI to generate MIDI songs, WavTool includes AI tools for composition, and Symphony V offers AI vocal synthesis.
Plugins like Izotope Neutron 4, TAIP, and Synthesizer V integrate AI features into DAWs. Neutron 4 uses machine learning for automatic audio processing. TAIP uses AI to mimic traditional effects, and Synthesizer V provides AI-generated vocalists.
To save computer memory, some plugins use cloud servers. For example, the Samplab plugin processes audio using resources from a remote server.
Impact
DAWs can be used in music classes to teach students how to use them and create their own music. A study by Indonesia University of Education found that using DAWs helps students learn music production by themselves. A study by the University of Milan made DAWs available for children.
DAWs are used in hip hop and EDM music to repeat musical parts. As music production moves to laptops, making music is now done in bedrooms instead of professional studios.
