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
