: Also, I remember hearing that "System 7 Sounds" were actually
: identical to a better-known format. AAUI or AU or AIFF or something. If
: you knew which one, you could just copy them to Virtual Desktop,
: mass-rename them with DOS, and convert them with some advanced Windows
: sound-editing program.
Perhaps the codec encoding them is identical (most likely to AIFF, which was Apple's standard audio format for a long time), but the file format is definitely not the same. "System 7 Sounds" are SND# resources, stored in the resource fork, and thus only compatible with file systems which understand resource forks.
However, if you can get what you want in System 7 Sound format, and find a copy of the old app "SoundApp" (or something similar to it, but it was my favorite), you can do a quick and easy batch-convert from System 7 to pretty much any damn audio format ever conceived of.
