[sdiy] ADC/DAC to Microprocessor for Audio

[William Berzinskas]

Looking over the net,  it seems the general consensus is to not try what i want to do..  but all that aside..

What circuitry is need to go into a adc and out of a dac for use with audio and a pic18?   most likely, the adc/dac would be single supply (i'm mostly limited to dip here)..  so, i'd need to deal with that..  

also what kind of input filtering is necessary?   and whats this about output reconstruction filter?    



On a side note..  I've tried some simple stuff like this before, but no good results because the aforementioned were not handled..  just trying to sample and output data..    one thing i noticed.  for instance: if i was working with 8 bits..  how would i handle situations that caused an overflow?  is there some averaging of bits here or something i should be aware of? 

thanks in advance
