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

2003-12-31, 16:31
What is the whole goal here? I just rip/encode with EAC and LAME. I have a
few albums that have slightly lower volume than others but I don't see the
need to normalize my whole collection down to 89db just to prevent having to
adjust the volume knob once in a while.

So again, what is the goal here? If you are doing normalization there are
lots of additional factors that can be screwing things up for you.

If you are saying that the squeeze is not loud enough once everything is
normalized, welcome to the wonderful world of normalization, you can always
buy a more powerful amplifier.

Probably not the ripping, but the encoding. I have plenty of
EAC/LAME --alt-preset standard encodes that are clipped
'out of the box' according to mp3gain.

It might help if Simon tells us what he's trying to
accomplish: a similar volume throughout his collection
or simply trying to reduce clipping.
