normalize mp3's

[Will]

I'm looking for a program which can normalize the sound level in mp3s in
batch mode eg. I want to be able to select 200 mp3s and have the program
automatically normalize them to a similar volume.
The bitrate and quality must remain as original. Any help would be greatly
appreciated.

Thanks Mike, nice program. I must have missed this one lurking somewhere
else. I just tried it on about a dozen files I had that were way to loud.
Album mode, did a nice job dropping the volume down.

MediaMonkey (freeware) also has a levelizer under the Tools menu

How do these normalizers work? I hope they don't make all the
recordings the same as the lowest, or highest ones. Thanks...

With MP3 Direct Cut you can set the level required. I don't know about Media
Monkey.

They (the good ones) set the apparent level (what it sounds like, not
what a meter says it is - the two can be very different) to a
normalized mp3 level, but it's adjustable for your taste. It's not a
destructive process, though - if you reverse it, you'll get back the
level you had originally. Read <http://replaygain.hydrogenaudio.org/>
to get a better idea.

I'd recommend http://mp3gain.sourceforge.net/. Good proggy, free & open
source.

I tried MP3 Gain and it is very good.
It doesn't just find the loudest part of the song and then bring the song up
or down to a preset level it actually looks at characteristics which make
the song sound loud.

From the help file:
" Most programs that "normalize" sound files do so by adjusting all the
samples so that the loudest single sample is at some specified value. This
is not a good way to make all the files actually have the same loudness.
First of all, the human ear does not hear the loudness of single samples. It
averages out sounds over time. Secondly, today's popular music CDs are
heavily compressed. The sound engineers making the CD raise the average
level so that it sounds much louder, while compressing the loudest parts so
that they don't distort. "

I use Mp3 Gain pretty much exclusively. There are the occasional songs
where it seems a bit less effective on than others, but for the 80-90% bulk
processing, it is excellent ... and free!
