Howdy, Any of you privillaged/lucky enough to have access to a Sun Sparcstation. It seems that that have sampling capability, but the manuals are week as far as specs go. Any details, comments, references would be great. Thanks Daniel Pirone

The audio feature of the SparcStation has been pretty well described in comp.sys.sun; inquiring minds who want to know should look there. Briefly, there is a directory (/usr/demo/sound) that includes a little Sunview program to display and playback a sample. It comes with a sample of the Sun CEO blathering about Sun meeting challenges, or something like that. The chip is a stock 8-bit, 8k samples/sec telephone chip (similar, if not identical, to the one in the NeXT). It's raison d'etre is voice email. It is not suitable for reasonable quality audio reproduction. The chip is accessed via /dev/audio; you can cat a digitized sample to this device and hear it. Comp.sys.sun had pin-outs for the non-standard cables you'll need if you want to record your own samples via the mic input. The program sound.c in the /usr/demo/sound directory will provide all the gory ioctl details for anyone who is interested.

However, note that this is 8-bit D/A. It's really only "voice-quality," clearly not good enough for a music application, but still fun to play around with. I can't point you at any docs, but there is a sample audio program, including source, that comes with SunOS. It's rather limited, but it will sample and playback, showing the waveforms in real time. You might want to check it out. Look in the directory /usr/demo/sound. -Doug Doug Cook dmc@sun.com XView Group cook@gandalf.ucdavis.edu Sun Microsystems, Inc.
