       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

       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.


       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.


       -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

              list parameters in raw output format for use with external programs

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

              separate lines by char NUM (numerical ASCII code) (default="0x0a")

              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:

              remove junk before first frame

              remove junk after last frame

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

              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

              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)

              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

              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

              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

              print version, then exit successfully
