Digital audio workstation

A digital audio workstation (DAW) is an electronic device or application software used for recording, editing and producing . DAWs come in a wide variety of configurations from a single software program on a laptop, to an integrated stand-alone unit, all the way to a highly complex configuration of numerous components controlled by a central computer. Regardless of configuration, modern DAWs have a central interface that allows the user to alter and mix multiple recordings and tracks into a final produced piece. DAWs are used for producing and recording music, songs, speech, radio, television, soundtracks, podcasts, sound effects and nearly any other situation where complex recorded audio is needed. Early attempts at digital audio workstations in the 1970s and 1980s faced limitations such as the high price of storage, and the vastly slower processing and disk speeds of the time. In 1978, Soundstream, who had made one of the first commercially available digital audio tape recorders in 1977, built what could be considered the first digital audio workstation using some of the most current computer hardware of the time. The Digital Editing System, as Soundstream called it, consisted of a DEC PDP-11/60 minicomputer running a custom software package called DAP (Digital Audio Processor), a Braegen 14"-platter hard disk drive, a storage oscilloscope to display audio waveforms for editing, and a video display terminal for controlling the system. Interface cards that plugged into the PDP-11's Unibus slots (the Digital Audio Interface, or DAI) provided analog and digital audio input and output for interfacing to Soundstream's digital recorders and conventional analog tape recorders. The DAP software could perform edits to the audio recorded on the system's hard disks and produce simple effects such as crossfades. By the late 1980s, a number of personal computers such as the Yamaha CX5M, Macintosh, Atari ST, and Amiga began to have enough power to handle digital audio editing.
