Addendum to my post #56 above: I did now compare purchased (in 2018) tracks from four download stores, HighResAudio, HDTracks, Acoustic Sounds, and Presto. I couldn‘t find any difference between any two stores to yield a null all over the frequency band. Very bad result given this is all purchased music!
I will try three approaches when my time allows:
Remark: I did not look into streaming services (yet).
I will try three approaches when my time allows:
- If mattmontag is correct in saying (April 2020) that all UMGs are clean now, one can hope that the stores replace their files. I‘ll check whether a store allows me to re-download those older purchases of mine. But then, how to find out whether I‘m getting a clean copy now?
- I might check how a purchased downloaded CD quality file compares to a dBpoweramp AccurateRip of an original physical CD. The AccurateRip fingerprint or the flac audio checksum will be the easiest things to do.
- The most difficult thing to do with DeltaWave will be to evaluate the difference between a purchased downloaded hi-res file and its physical CD rip. Most of the time, those will be different masters; and even if they are from the same mastering, it might be challenging to align them perfectly.
