Hi, Anyone know how to store data within an audio file? I need to put together an audio CD that has embedded data in it that I can use to sync the embedded hardware to. Any help or pointers appreciated. Cheers Mark
Provided it can be played on standard equipment (i.e. CD, DVD, mini disk etc) If it's gotta be standard audio equipment, then I think you're gonna have to use in-band audio - any clever tricks with merged data would require a specialised player to handle that data. As you're not worried about audio quality, why not just use one side of the stereo CD audio for your sound, and the other side for sync tones? Note that MD uses lossy compression - I don't think that'd be good for data, and you'd probably also have to check carefully for any effects on signalling tones (the compression relies on psycho-acoustics, and is designed for reproducing music for human listeners - not data or tones for machines!) The same applies to MP3 and Real Audio (TM?)
