That's part of what confused me. He seemed to be saying the digital signal itself would be "high freq" noise. Given that a digital to audio converter (DAC) would be needed. I would think that one would be chosen that would result in the cleanest audio signal possible.

He then states that a signal like that with out filtering would be "digital sounding" which is why they added they Butterworth filter. I really wanted to find if your tests had any way to determine if the rolloff and distortions were the addition of that filter or just hardware that's not up to the job of producing a clean signal.

Once again please forgive any misunderstandings of basic audio theory I may exhibit in how I phrase this. I'm very new to this and am studying up on it but there's a number of things I know I still don't have a clear understanding on.
