First AmigaOS4 port by Thematic

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.

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.

mp3gain version 1.6.2
copyright(c) 2001-2009 by Glen Sawyer
uses mpglib, which can be found at http://www.mpg123.de
Usage: mp3gain [options] <infile> [<infile 2> ...]
	-v - show version number
	-g <i>  - apply gain i without doing any analysis
	-l 0 <i> - apply gain i to channel 0 (left channel)
	          without doing any analysis (ONLY works for STEREO files,
	          not Joint Stereo)
	-l 1 <i> - apply gain i to channel 1 (right channel)
	-e - skip Album analysis, even if multiple files listed
	-r - apply Track gain automatically (all files set to equal loudness)
	-k - automatically lower Track/Album gain to not clip audio
	-a - 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)
	-m <i> - modify suggested MP3 gain by integer i
	-d <n> - modify suggested dB gain by floating-point n
	-c - ignore clipping warning when applying gain
	-o - output is a database-friendly tab-delimited list
	-t - mp3gain writes modified mp3 to temp file, then deletes original 
	     instead of modifying bytes in original file (default)
	-T - mp3gain directly modifies mp3 file (opposite of -t)
	-q - Quiet mode: no status messages
	-p - Preserve original file timestamp
	-x - Only find max. amplitude of file
	-f - Assume input file is an MPEG 2 Layer III file
	     (i.e. don't check for mis-named Layer I or Layer II files)
	-? or -h - show this message
	-s c - only check stored tag info (no other processing)
	-s d - delete stored tag info (no other processing)
	-s s - skip (ignore) stored tag info (do not read or write tags)
	-s r - force re-calculation (do not read tag info)
	-s i - use ID3v2 tag for MP3 gain info
	-s a - use APE tag for MP3 gain info (default)
	-u - undo changes made (based on stored tag info)
	-w - "wrap" gain change if gain+change > 255 or gain+change < 0
	      (use "-? wrap" switch for a complete explanation)
If you specify -r and -a, only the second one will work
If you do not specify -c, the program will stop and ask before
     applying gain change to a file that might clip
