This is a feature I would really like to have. I tried to circumvent it a while ago when I was playing with the Web Audio API by allowing an iOS user to "upload" a video, from which I would then extract the audio using decodeAudioData. Unfortunately it returned an error on callback in iOS. Perhaps it could still work by processing said video on the server and sending back the audio, but keeping everything client-side was my requirement.
