How is the ACID specific info embedded in a wav file? -ACID Product Family

Subject:How is the ACID specific info embedded in a wav file? Posted by: Neole Date:2/29/2004 12:05:52 PM I am trying to get a custom software made that will intelligently ACIDise a folder of wav loops. Does anyone have any information on how and where the ACID information (i.e. loop/disk based, number of bars, pitch etc) is embedded in a wav file? Or where I could get this info from? Since a number of software use this info(chicken systems translator, acidizer, sonar) I guess it would be public knowledge. I need technical details on this so I can pass it on to my programmer.

Reply by: Neole Date:3/1/2004 8:56:18 AM Ok I found this file that can read the chunks of a riff file - http://www.daubnet.com/english/riffview.html ( http://www.daubnet.com/ftp/riff13.zip ) Here's some information on the wav/riff file format - http://www.daubnet.com/formats/RIFF.html I see using the tool that an acidised file has 24 bytes of extra data in the 'acid' chunk as compared to the unacidised version. The second file is acidised, the first is unacidised. http://www.eleena.com/stuff/loop1.wav http://www.eleena.com/stuff/loop1a.wav Now can anyone figure out what those bits in the ACID chunks specifiy? Which number specifies what and how to add the chunk to a wav file so we can embed it with information that it is a loop file and has x number of bars in the loop? If anyone can then making an acidizing program to acidize whole CDs of wav loops will be very easy.
