Connect the ADC to the junction of the Cap and the resistor. Then the audio signal will be summed with Vcc/2 and give you +/- 511 counts on your ADC results after subtracting 512. As long as your audio input doesn't exceed +/- VCC/2 you won't clip. -----Original Message----- From: c45a6 [mailto:clone45@hotmail.com] Hello again! I drew out a quick schematic for the AC coupling. I wasn't sure exactly how to wire it up. Can you take a look at it and let me know if it's what you mean? The values of the capacitor pictured are wrong. Don't worry about that: http://www.voxglitch.com/images/coupling_test.bmp Also, was there any advice for me on how to NOT clip the lower half of my audio signal when doing the A/D conversion?
