I only did this experience w. the sound files I created at www.motorcityimprov.com/autoeq/ but I had no clicks and pops.. Just tones and humms.

Also, my mic had poor bass response (but my system has a subwoofer) so the first band cranked itself to +9dB with AutoEQ. I'm going to bring that number down a bit because it's due to my microphone not picking up that frequency.

Rob also mentioned that having the proper volume level helps. His recommendation of -20dB worked great for me.
