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
Hello Alex, Thanks for the information on .WAV files. Can you make the datachunk array any size you like? The application I had in mind requires regular data elements so that the embedded side syncs with the music. Can I do this with the .WAV format? Thanks again 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...
