View Full Version : MP3 quality poor due to low volume levels, notcompression.

I use mp3gain album gain at the default level (89 dB) without
any noticeable problems (to me). I obviously have to turn it
up a bit compared to a recent popular music CD, but this is
expected and the change is not too drastic. I am curious why
you are using your method instead of album gain.

Do you have the volume level of your slimp3/squeezebox set
to max?

How could ripping a CD introduce clipping? You're just
extracting the WAV data off of the disc. If you have a decent
drive or use the right software, its a perfect copy.

I expect album gain normalizes an entire disc as a single
unit, so the highest peak of the entire album is at 0db. You
seem to be normalizing on a per-track basis, so the highest
peak of every track is at 0db.
