Hi all, I am looking for a solution for an audio player that has the ability to play two audio files at the same time, but when clicking "before" it mutes one version of it, which would be the "After" side, and vice versa. Something similar to the audio player on this website wwwDOTdoctormixDOTcom. I've been looking everywhere for something but I can't come up with anything. Any ideas? Thanks!
