+mp3gain (adjusts mp3 files so they have the same volume)
+
+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.  Also, the changes MP3Gain
+makes are completely lossless. There is no quality lost in the change
+because the program adjusts the mp3 file directly, without decoding
+and re-encoding.

+.TH MP3GAIN "1" "April 2009" "mp3gain version 1.4.6" "User Commands"
+.SH NAME
+mp3gain \- analyzes and adjusts mp3 files so that they have the same volume
+.SH SYNOPSIS
+.B mp3gain
+[\fIoptions\fR] \fI<infile> \fR[\fI<infile 2> \fR...]
+.SH DESCRIPTION
+Tired of reaching for your volume knob every time your mp3 player changes to a new song?
+MP3Gain analyzes and adjusts mp3 files so that they have the same volume.
+.PP
+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.
+.PP
+Also, the changes MP3Gain makes are completely lossless. There is no quality lost in the change because the program adjusts the mp3 file directly, without decoding and re-encoding.
+.SH OPTIONS
+.TP
+\fB\-v\fR
+show version number
+.TP
+\fB\-g\fR <i> 
+apply gain i to mp3 without doing any analysis
+.TP
+\fB\-l\fR 0 <i>
+apply gain i to channel 0 (left channel) of mp3
+without doing any analysis (ONLY works for STEREO mp3s,
+not Joint Stereo mp3s)
+.TP
+\fB\-l\fR 1 <i>
+apply gain i to channel 1 (right channel) of mp3
+.TP
+\fB\-r\fR
+apply Track gain automatically (all files set to equal loudness)
+.TP
+\fB\-k\fR
+automatically lower Track/Album gain to not clip audio
+.TP
+\fB\-a\fR
+apply Album gain automatically (files are all from the same
+album: a single gain change is applied to all files, so
+their loudness relative to each other remains unchanged,
+but the average album loudness is normalized)
+.TP
+\fB\-m\fR <i>
+modify suggested MP3 gain by integer i
+.TP
+\fB\-d\fR <n>
+modify suggested dB gain by floating\-point n
+.TP
+\fB\-c\fR
+ignore clipping warning when applying gain
+.TP
+\fB\-o\fR
+output is a database\-friendly tab\-delimited list
+.TP
+\fB\-t\fR
+mp3gain writes modified mp3 to temp file, then deletes original
+instead of modifying bytes in original file
+.TP
+\fB\-q\fR
+Quiet mode: no status messages
+.TP
+\fB\-p\fR
+Preserve original file timestamp
+.TP
+\fB\-x\fR
+Only find max. amplitude of mp3
+.TP
+\fB\-f\fR
+Force mp3gain to assume input file is an MPEG 2 Layer III file
+(i.e. don't check for mis\-named Layer I or Layer II files)
+.TP
+\-? or \fB\-h\fR
+show this message
+.TP
+\fB\-s\fR c
+only check stored tag info (no other processing)
+.TP
+\fB\-s\fR d
+delete stored tag info (no other processing)
+.TP
+\fB\-s\fR s
+skip (ignore) stored tag info (do not read or write tags)
+.TP
+\fB\-s\fR r
+force re\-calculation (do not read tag info)
+.TP
+\fB\-u\fR
+undo changes made by mp3gain (based on stored tag info)
+.TP
+\fB\-w\fR
+"wrap" gain change if gain+change > 255 or gain+change < 0
+(use "\-? wrap" switch for a complete explanation)
+.PP
+If you specify \fB\-r\fR and \fB\-a\fR, only the second one will work.
+If you do not specify \fB\-c\fR, the program will stop and ask before
+applying gain change to a file that might clip.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.
