The VOLUME resolution is 8 bits... I don't know if it's possible to do psuedo-16 bit volume. The PLAYBACK resolution is 46720 Hz, or at least, that's the maximum rate the Sonic Blaster Software will let you play a sample back. I can't find the actual maximum limit in any of my books. >oh yeah, is it possible to de-multiplex more than two channels of sound >from the GS? I think I read somewhere that it is possible... It's possible to de-multiplex up to 8 channels. The address of the current channel can be found on pins 4,5, & 7 of the 7 pin Molex connector on the front right corner on the GS motherboard. Pin 6 is is the channel address strobe. >Ken Morton "A vacant engineer rides on a >v097pba8@ubvms.Bitnet train of thought that will not >v097pba8@ubvmsd.cc.buffalo.edu lead him home" - Edie Brickell ---------------------------------------- BITNET-- mquinn@utcvm <------------send files here pro-line-- mquinn@pro-gsplus.cts.com
