I wish we could get Don't forget about adding channels (not adding waveforms) and volume modulation. When you use all 8 bits the sample doesn't sound that bad. The dissatisfaction occurs during the quiet parts of the sample when the quantization is relatively large. If you use volume modulation you can adjust for this and use 8 bits keeping the relative quantization error the same thru the sample. Now for my suggestion, The waveform and volume D/As do not change simultaneously which gives a short glitch in the sound when doing volume modulation. How about having a S/H or synchronous action? _____________________________________________________________________________ Jerry J. Trantow | The concern for man and his destiny must always 1560 A.
