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
Can you make the datachunk array any size you like? I think so Mark, I don't know how much is the size limit ( if it really exist ) but, remember that you can have just one track of music inside a CD, it means 74 seconds, something around 650MB of data in just one WAV file, so I'm not sure about a limit. I also think that these regular elements can be put inside the file without problems.
the data on an audio CD isn't a WAV file; when you burn an audio CD (ie, one you can play on an audio CD player) your burner performs the conversion. BTW: that's 74 minutes, not seconds!
that's 74 minutes, not seconds! Thanks Andrew. the data on an audio CD isn't a WAV file Oh that's why I didn't found the WAV structure inside the binary image of my Audio CD... hummmm.. I really wasted a lot of time dumping 473MB of binary numbers in my hex editor...
