A digital audio workstation (DAW) is an electronic system designed to record, edit and play back digital audio. A key feature of DAWs is the ability to freely manipulate recorded sounds.

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 analog-to-digital (ADC) and/or digital-to-analog (DAC) signal conversion. For example, a workstation could have eight discrete audio inputs, and two or more audio outputs for playback monitoring or routing signal to other devices. Systems can have as few as two mono inputs and outputs  the discrete audio inputs and outputs provide for simultaneous multitracking dual mono sources or stereo recording. A professional DAC performs the same function as a common sound card, but is generally of higher quality and offers sonic or functional advantages when compared with its consumer cousin.

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 Cubase, Nuendo, Logic Pro, Pro Tools, Adobe Audition, SADiE 5, Sony Sound Forge, Samplitude, Soundscape, SONAR, ACID Pro, FL Studio (formerly Fruityloops), Ableton Live, Tracktion or Digital Performer, some of which is free software such as Audacity and Ardour. Besides having high-end sound cards most DAWs also require a large amount of RAM, fast CPU(s) and sufficient free hard drive space.

Varieties

DAWs generally come in two varieties:

Computer-based DAWs

Consist of three components: a computer, an ADC-DAC, and digital audio editor software. 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 DAWs

Consist of a mixing console, control surface, audio converter and data storage in one device. 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. 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.
