Yeah, but we aren't talking about listening to generation after generation of bit perfect digital copies here. We are talking about converting analog to digital and then back again to analog
Maybe I wasn't clear enough? This test sent music out the sound card's analog output back into its analog input. It did indeed test multiple conversion generations. BTW, I have all 21 files if anyone cares or doesn't trust what I'm claiming. Each file is slightly different than the previous which is easily verified with a null test. I just didn't want to waste the space and bandwidth on my site to host all the in-between generations.
