I also would like to use voice modulations for synth sounds so high quality is not necessary. 4khz might be fine for the intended purpose; something better than r2d2 but not quite bad telephone connection. in between. all I need the arduino to do is sample the audio and send the data to pure data where I can deal with it there. on the arduino, I just want the signal with no

I'd check the Arduino forums for using an Arduino to digitize audio, I think some people have documented how to do it.
