To thwart Youtube muting the audio track to your video, consider encoding the audio in the video itself, which can be recovered with a special player. How should we do this to survive video compression?
Some calculations: 64kbit/sec compressed mono audio is 327 bytes per frame (25fps). 320x240 uncompressed YUV 420 video is 115200 bytes per frame (350 times more).
Everything old is new again, with audio tracks on the edges of movie film.
