Club CDFreaks - Knowledge is Power - View Single Post - Flac: I still do not understand two things about it (replayGain and compression).

Andrius · 10-05-2007

I have been reading a lot, but still I do not understand these two things:

* It is stated that Wav files encoded with Flac and then decoded to Wav are identical to the original Wav files. ReplayGain, if I understand it right, changes the volume level of tracks, - so how can the decoded file be identical to the original, if the volume level was changed? ReplayGain is usually set by default.

* What is the difference between Flac compression levels? Is it just the issue of speed of encoding/decoding and nothing more (no difference in quality, in playback and seeking speed and quality)?
