DESCRIPTION

       This  manual  page  documents briefly the mp3check command.  This manual page was written for the Debian GNU/Linux distribution because the
       original program does not have a manual page.

       mp3check is a program that checks mp3 files for consistency and prints several errors and warnings. It  lists  stream  attributes  (color).
       Layer 1,2,3, mpeg1.0+2.0 are currently supported. CRC check for layer 3.  mp3check is very useful for incomplete mp3 detection as it can be
       used to scan through your mp3 collection and find all mp3s that aren't perfect. Good for use with Napster and  other  bulk  downloading	of
       mp3s.

OPTIONS

       These  programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). Options can be specified in any
       order and mixed with files. Option scanning stops after a double dash (--) to allow files beginning with a dash.  A summary of  options	is
       included below.

       mode:

       -l --list
	      list parameters by examining the first valid header and size

       -c --compact-list
	      list  parameters	of  one file per line in a very compact format: version (l=1.0, L=2.0), layer, sampling frequency [kHz] (44=44.1),
	      bitrate [kbit/s], mode (js=joint stereo, st=stereo, sc=single channel, dc=dual channel), emphasis (n=none,  5=50/15  usecs,  J=CCITT
	      J.17), COY (has [C]rc, [O]riginal, cop[Y]right), length [min:sec], filename (poss. truncated)

       -e --error-check
	      check crc and headers for consistency and print several error messages

       -m --max-errors=<int>
	      with -e: set maximum number of errors to print per file (0==infinity) (range=[0..])

       -a --anomaly-check
	      report all differences from these parameters: layer 3, 44.1kHz, 128kbps, joint stereo, no emphasis, has crc

       -d --dump-header
	      dump all possible header with sync=0xfff

       -t --dump-tag
	      dump all possible tags of known version

       --raw-list
	      list parameters in raw output format for use with external programs

       --raw-elem-sep=NUM
	      separate elements in one line by char NUM (numerical ASCII code) (default="0x09")

       --raw-line-sep=NUM
	      separate lines by char NUM (numerical ASCII code) (default="0x0a")

       --edit-frame-byte=P
	      modify a single byte of a specific frame at a specific offset; B has the format 'frame,offset,byteval', (use 0xff for hex or 255 for
	      dec or 0377 for octal); this mode operates on all given files and is useful for your own experiment with	broken	streams  or  while
	      testing this toll ;-)

       fix errors:

       --cut-junk-start
	      remove junk before first frame

       --cut-junk-end
	      remove junk after last frame

       --fix-headers
	      fix invalid headers (prevent constant parameter switching), implies -e, use with care

       --fix-crc
	      fix  crc	(set  crc  to the calculated one), implies -e, use with care (note: it is not possible to add crc to files which have been
	      created without crc)

       disable error messages for -e --error-check:

       -G --ign-tag128
	      ignore 128 byte TAG after last frame

       -R --ign-resync
	      ignore invalid frame header

       -E --ign-junk-end
	      ignore junk after last frame

       -Z --ign-crc-error
	      ignore crc errors

       -N --ign-non-ampeg
	      ignore non audio mpeg streams

       -T --ign-truncated
	      ignore truncated last frames

       -S --ign-junk-start
	      ignore junk before first frame

       -B --ign-bitrate-sw
	      ignore bitrate switching and enable VBR support

       -W --ign-constant-sw
	      ignore switching of constant parameters, such as sampling frequency

       --show-valid
	      print the message 'valid audio mpeg stream' for all files which error free (after ignoring errors)

       disable anomaly messages for -a --anomaly-check:

       -C --any-crc
	      ignore crc anomalies

       -M --any-mode
	      ignore mode anomalies

       -L --any-layer
	      ignore layer anomalies

       -K --any-bitrate
	      ignore bitrate anomalies

       -I --any-version
	      ignore version anomalies

       -F --any-sampling
	      ignore sampling frequency anomalies

       -P --any-emphasis
	      ignore emphasis anomalies

       file options:

       -r --recursive
	      process any given directories recursively (the default is to ignore all directories specified on the command line)

       -f --filelist=FILE
	      process all files specified in FILE (one filename per line) in addition to the command line

       -A --accept=LIST
	      process only files with filename extensions specified by comma separated LIST

       -R --reject=LIST
	      do not process files with a filename extension specified by comma separated LIST

       -3 --only-mp3
	      same as --accept mp3,MP3

       --xdev do not descend into other filesystems when recursing directories (doesn't work in Cygwin environment)

       --print-files
	      just print all filenames without processing them, then exit

       output options:

       -s --single-line
	      print one line per file and message instead of splitting into several lines

       --no-summary
	      suppress the summary printed below all messages if multiple files are given

       -g --log-file=FILE
	      print names of erroneous files to FILE, one per line

       -q --quiet
	      quiet mode, hide messages about directories, non-regular or non-existing files

       -o --color
	      colorize output with ANSI sequences

       -b --alt-color
	      colorize: do not use bold ANSI sequences

       --ascii-only
	      generally all unprintable characters in filenames etc are replaced by '!' (ASCII 0-31) and '?' (ASCII  127-159),	with  this  option
	      present the range ASCII 160-255 (which is usually printable: e.g. ISO-8859) is also printed as '?'

       -p --progress
	      show progress information on stderr

       common options:

       -0 --dummy
	      do not write/modify anything other than the logfile

       -h --help
	      print this help message, then exit successfully

       --version
	      print version, then exit successfully
