Channel Strip

Channel Strip is a Web Audio experiment created with HTML5, CSS3, JavaScript, and the Web Audio API. This web app is a stand alone audio channel strip that allows an audio signal to be boosted, attenuated, equalized, panned, compressed and muted in the browser. The audio source is derived from user media via file select input. Simply choose an audio file (mp3 or wav, etc.) from your hard drive and click Play to get the party started.
