I >believe that to do this we must increase the sampling rate. Is this Two areas could be improved, the sample rate and the resolution. I think the sample rate is pretty simple to deal with. 20 khz requires a min. of 40 khz sample rate, but in the real world somewhere above 40. That's one sample every < 25 usec. Not exactly taxing on Amiga's bandwidth (I know it could _get_ taxing, but it's not inherently). But 8 bits of resolution means audible quantization noise, which could only be improved by increasing the number of bits. I wish we could get 16 bit sound on the Amiga, it would really sound great. But that would require significant redesign of the sound chip, and I don't know how it could be made compatible with old software. Maybe a dual-mode design that only uses the 8 MSbits of the sound channel for old stuff. Just dreaming :-). --Steve ------------------------------------------------------------------------- {uunet,sun}!convex!swarren; swarren@convex.COM
