if I hex-edit the contents of an
existing .snd file, it seems to have a header chunk that the SND
resource doesn't
Isn't it the case that snd is an ambiguous format, and could mean
either a resource fork containing a 'snd ' resource (which may contain
either sampled sound or commands to drive the sound synth), or else a
data fork containing sampled sound data in the NeXT/SUN format?
Also, depending upon how old it is, the 'snd 'resource could be in
format 2 (sampled sound only), which lacks some header fields found in
format 1 (sampled sound or synth), both of which are both different
from NeXt/SUN .snd.
Point being, "convert 'snd ' to .snd" could mean a few different
things...
Perhaps these links may help:
