I've downloaded a few albums in FLAC where the download also includes such things as 'accurip', 'log reports', 'TAU analyzer graphs' etc. All very professional looking stuff which suggests (to me anyway) that the CP rip you've downloaded is of the highest quality.
When I make FLAC copies of my own CD's, I use Wavepad (which is similar to Audacity). It's very simple, load the CD, save as FLAC and that's it â€“ no logs, graphs or other documents.
Which makes me wonder â€“ are my FLAC files as good as the ones I've downloaded?
