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 unpritable 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
