Hi all, I'm looking for something like mp3gain:but for .wav-files. Anything out there ? Volume level in sound files is usually called 'normalisation' ...so you want to raise the normalisation level. I use a non-free product for this (CoolEdit, now Adobe something or other) but (free) Audacity may also do the trick.
The problem is, that mp3gain is doing something special:

MP3Gain does not just do peak normalization, as many normalizers do. Instead, it does some statistical analysis to determine how loud the file actually sounds to the human ear.
The original homepage of the ReplayGain algorithm is highly

How can it do that? How loud a noise sounds to the human ear will
vary from one person to another. If the normalise level is set to
high, the output will sound distorted at peak levels. If too low, it
will need a high volume level on the player which will introduce
excessive background noise (hiss etc).
The purpose of normalisation is to adjust the output sound of a
track to improve it's signal-to-noise ratio and an added benefit is
to normalise a number of tracks at the same level to produce similar
output volume levels. In my case I normalise all .wav files at 96% for
all songs before encoding into MP3. That way every CD I burn can use
the same control settings on the player.

Thank for mentioning the term I was looking for.Actually I want to LOWER the normalization level.
Fine. That should reduce any clipping you may currently have.
I've no idea exactly what you're doing but if you're preparing a
number of tracks for CD burning, best to adjust to the same levels.
The s/w I mentioned also has other features - remove background hiss,
clicks/scratches/pops etc etc etc.

I should have been more clear, Audacity does this, but I need a batchfunction, don't want to do a few dozen one by one.
OK. The utility Thorsten recommended looks fine for you.
Good luck :-)
What I was doing (and have done now) is reducing the level of the wavs
that are included in the program, they were way too loud compared to my
mp3 collection. I was tired of fiddling with the volume controls of both
windows and the independent volume control of my also excellent
audioplayer, Billy (abandonware):

Actually the program gave me some errors, I gave up on it and ended up
converting the wavs to mp3 with Razorlame (which I already had but forgot
about):
normalizing them using Mp3gain and converting them back to wavs with
Razorlame. They're just simple wavs (clicks on moves, draw offered etc),
so I don't care much about any quality loss.

Good question, gives me the opportunity to mention a great piece offreeware: Babaschesshttp://www.babaschess.net/a chess interface I use to play on the excellent Free Internet ChessServer aka FICS:http://www.freechess.org/
I might have a closer look at this sometime ...I've always been a
chess player, albeit not brilliant :-(

Billy deserves publicity on this NG since it's free. There's another
free one called *1-by-1* which does a similar thing and is quite
popular.

I also tried out this utility with a spare wavfile and compared it to
CoolEdit. What WaveGain actually does is to normalise .wav files to
100% (defined as the highest peak level without clipping), which is
not something I normally recommend for important wavfiles (music etc).
I use 95-96% to be safer.
There may be a way of telling it what level to normalise to.
I see you are using Razorlame and presumably Lame itself - that's good
news - they're probably the best encoders available.
MP3Gain does not just do peak normalization, as many normalizers do. Instead, it does some statistical analysis to determine how loud the file actually sounds to the human ear. How can it do that? How loud a noise sounds to the human ear will vary from one person to another. If the normalise level is set to high, the output will sound distorted at peak levels. If too low, it will need a high volume level on the player which will introduce excessive background noise (hiss etc).
as it's said in short description (and I also included all
necessary links), it's not precise, it's about approximation,
"some statistical analysis"...
What you talk about is within other extreme. When I use MP3Gain
I mostly adjust by 1,5 to max 6 db. This is not really where
background noise comes in, it's just what is it's written purpose,
have the files sound mostly in comparable volume. And for me it
works.
