could anyone out there tell me how to playback digitized sound samples on the ST? i have tried taking say 8-bit linear digitized audio samples (00 - ff amplitudes) and piping them to the sound chip directly to the 4-bit d/a level register on the chip (using a table lookup to get as close to the 4-bit companded output of the chip as possible) but the results are very noisy and always sound like hisses (even plain sine waves). i know programs like STSPEAK.TOS and the various playback programs on bbs's can get reasonably decent sound. are they using some undocumented features i don't know about? atari was no help (jfeagans and some h/w guys did not know how to do it...). please reply via email or by voice at 617/486-1408. your input is greatly appreciated.... -bill
