	Sure, but you were taking 8-bit samples, probably at 8khz.  Take
a look at the increase in needed throughput to support 16-bit samples at
sampling rates of better than 40khz and you'll see that the Amiga does not
have the power to handle it.  I have looked at a number of specialized hardware
designs to resolve this.

	I would like to, at some time, build a professional quality audio 
processing system.  I figure I could do it now with the A2000, but the 
price to the user would be about $1300 above the cost of the A2000, which
means the market (musicians, not computer users) would probably not 
accept it.  Still, for $2800 (all hardware, no software) it would be possible
to provide a truely open audio processing environment.  As a musician I'm
dieing to do this.  Maybe by summer...
