And? Can't play that with a redbook DA which is the point of MQA, to be backwards compatible.

Please show me where I can read up on that?

I think you need to read up on how MQA works. The redbook file is included and part of the MQA file, it will always be available. And you can play it with your redbook DA anytime, the MQA decoder adds on the extra information. However, the new file is a cleaned up version even for the redbook portion since they went back to the original files and "removed" the signature of the recording chain.

Sourpuss! That's not exactly nothing. And since it seems the adoption is going pretty well you'll now get hirez originals of recordings never available before.

Well that won't work since there is no defined start or end point for the files. The start and end of the files will not be exactly same.

I wan to compare two WAV files. One ripped straight from a CD and one recorded via SPDIF. I'm not interested in wave forms, I want to see bit level differences (there should be none ideally). I first tried using Diffmaker but just get nonsense results, more or less same as the original file, since the start point is a bit diffuse I was hoping it would be able to align the two and make a comparison of sorts? What could I be doing wrong?
