I see in IM VI all this stuff about VOX, but I can't seem to get any of it to work. Is it something the Apple sound driver supports or do they just document it as a standard for 3rd party drivers. Also, I'm having trouble with SndRecordToFile. It seems as though if I don't play a sound before calling it, the SoundManager gets corrupted, as if playing a sound somehow initializes the SoundManager. Please respond via email if possible. -ME

The VOX stuff isn't implemented in the 6.0.7 "built-in" sound input driver. I don't know about 7.0. Apple doesn't recommend that you use SndRecordToFile and SPBRecordToFile in 6.0.7, either. Apparently the code makes unauthorized calls to the Memory Manager at interrupt level, which may account for why you're having those problems. I would *hope* this particular problem is fixed in 7.0. The SPBRecord function is useful in its own right, but it's really at far too low a level to use as a convenient workaround.
