A digital audio workstation (D.A.W.) is an electronic device or computer software application for recording, editing and producing audio files such as songs, musical pieces, human speech or sound effects. 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.
