Hi there all.
Does anyone know of a program that will bring a bunch of MP3 files up to the same sound level. Thanks in advance.

$ aptitude search ~dreplaygain
p crip - terminal-based ripper/encoder/tagger tool
p libmpcdec-dev - MusePack decoder - development files
p libreplaygain-dev - Calculate ReplayGain information - development files
p libreplaygain1 - Calculate ReplayGain information - library
p mp3gain - Lossless mp3 normalizer with statistical analysis
p python-rgain - Replay Gain volume normalization Python tools
p qmmp - feature-rich audio player with support of many formats
mp3gain looks promising

$ aptitude show mp3gain
Package: mp3gain
State: not installed
Version: 1.5.2-r2-2
Priority: optional
Section: sound
Maintainer: Fabrizio Regalli <fabreg@fabreg.it>
Uncompressed Size: 171 k
Depends: libc6 (>= 2.7)
Description: Lossless mp3 normalizer with statistical analysis
MP3Gain analyzes and adjusts mp3 files so that they have the same volume. MP3Gain does not just do peak
normalization, as many normalizers do. Instead, it does some statistical analysis (using the replaygain
algorithm) to determine how loud the file actually sounds to the human ear.

MP3Gain can adjust the volume in a completely lossless way by modifying the mp3 file directly, without
decoding and re-encoding. This works with all mp3 players, i.e. no support for a special tag is required.

MP3Gain can also add replaygain compatible (APE) or ID3v2 gain tags to mp3 files.

Thanks for that. I am actually just running aacgain to see how it works. Basically a rewrite of mp3gain.
