DW>Just wondering if anyone out there is interested in getting an
 DW>expansion for their C64 which would sample audio and play it back under
 DW>software control. I've got a working prototype up and running which is
 DW>capable of playing back multiple recordings (up to 20 seconds max).  It
 DW>takes audio from a CD player or the C64 itself.
 
 Hmm.. interesting. I made an audio-digitiser a while ago for the 64 -
based on an amiga design. It used an ADC0802 (I think). The quality was
reasonable but nothing to write home about. As good as the datel one if
that gives you any ideas. It pluged into the user port. Playback was
through the 64.
  
 DW>Based on the ISD10xx family of speech recorders, it's cabable of better
 DW>than telephone sound quality (the 12 sec device is very clean).
 DW>Software is still in development.....anyone interested or got any
 DW>ideas?
 
 ISD10xx ?? Never heard of it! Can you give me some specs on this chip? ie
how many bits, whats the maximum recording rate in khz etc. What kind of
preamp do you use also. Mine is just your everyday op-amp.
