[sdiy] "lunetta"/CMOS sound-making equivalents in C Programming???

[nvawter at media.mit.edu]

yes, definitely.  although, many simple CMOS logic tasks on  
microcontrollers, such as dividers, can run decently fast, e.g. around  
100-500 kHz.

Another thing worth considering might be to dither and/or randomize  
the sample rate.  sound crazy?  sure is!  but it would distribute the  
noise floor a bit more equitably.

alternatively, external signals can trigger interrupts in the micro to  
execute the computations.  while that adds some overhead, for some  
classes of processing, it will curtail aliasing.
