Was downloading from a user on Soulseek some Mozart Edition albums, they were in wav format, unfortunately though it looks very much like they have or somebody has upsampled them from the original flac from here I'd imagine to wav, but they upsampled from 44,100 to 48,000 which only makes the file size larger and the frequencies higher than they should be, this was the result from Audacity and the Lossless Audo checker.
If someone wishes to burn an audio CD from these resulting files at 48,000 is impossible, they have to be 44,100, ok if they are originally ripped at 48,000 then that's fine as you can decrease from 48,000 to 44,100 but not increase from 44,100 to 48,000 as it will not make the quality any better.
I'm lucky that I can burn flac files to CD, but they need to be in 16bit & 44,100 in order to do so.
You never know the quality you're receiving on soulseek unlike on this marvellous site.
