'csnd' resource format - unknown - Feb 14, 2006 10:37 AM
I need to decode 'csnd' resources that I can get hex dumps from viewing some wolfenstien data files in res edit,
I know that they are the sound files in game and I've done a _lot_ of searching the net and found very little,
Any information about the format would be greatly appreciated and would help me hugley, I dont mind reinstalling MPW to compile classic app's if they can play csnd's.
I've found this much information so far:
Apple II File Type Notes Wrote:Here's how we would have upgraded AIFF to handle compressed audio, if we had
had a Format Version Chunk already in AIFF:
o Compression is optional. What follows is only for the compressed case.
o Don't change the format of the COMM Chunk. Existing programs can still
read it.
o Add a "Compression Descriptor" Chunk containing the 4-letter compression
type code and the compression name string. (The code is for programs.
The string is for alerts when the code is unrecognized.)
o Replace the SSND Chunk with a Compressed Sound-Data Chunk "CSND".
(Existing programs will ignore it.)
o Change the Format Version date (for the sake of alerts).
o Add the optional Saxel Chunk.

The Halestorm SoundMusicSystem lib is a predecessor to QuickTime Music Architecture (and beatnik).
Thanks to anyone who can give me some more information about this file format, I'm really stuck here, but I will continue searching.
Edit:
I've uploaded some of the sound files extracted from the game, with thier DLZSS'd counterparts (and the program to decompress them). I'm not 100% sure that im DLZSS'ing them correctly but I tested this algorithm before and it works for the bitmaps.
So for anyone willing to take a look http://www.fax.xmgfree.com/DLSZZ.zip
thanks again!

In case anyone is searching the net for csnd stuf and so on, I got it to work
The Halestorm SoundMusicSys.h has a function for exporting the waveform of a sound so I just copied and pasted the appropriate wolf3d code and made it play the sound and export it, then you can play the raw sound file with anything you like
