(e.g. compression, noise reduction, effects, voice recognition, plain=20 recording/playback) Also, you mention the M-Audio card, and also a DAC - are you wanting the=20 sound to come from/go to the PC or it to be based just around the PIC? What resolution do you need for the samples and what sampling rate, and=20 how much latency (if relevant) is OK? bandwidth needed - e.g. 20Khz,=20 10Khz? (e.g. for voice/music/beeps) Sorry for so many questions :-) --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
