Web Audio Multiple Track Waveform Editor

Inspired by Audacity, this project is a multiple track playlist editor written completely in javascript using the Web Audio API.

For help with setup check the wiki

###Try out the waveform editor!

Load tracks and set cues (track cue in, cue out), fades (track fade in, fade out) and track start/end times within the playlist. I've written up some demos on github for the different audio fade types in the project.

Save your progress by outputing editor state json. Localstorage has been used to save/restore editor state.
