mp3check version 0.8.7

Usage: [OPTIONS, FILES AND DIRECTORIES] [--] [FILES AND DIRECTORIES] this program checks audio mpeg layer 1,2 and 3 (*.mp3) files for consistency (headers and crc) and anomalies 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=N with -e: set maximum number of errors N to print per file (default 0==infinity) (range=[0..]) -a --anomaly-check report all differences from these parameters: layer 3, 44.1kHz, 128kB, 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=N separate elements in one line by char N (numerical ASCII code) (default="0x09") --raw-line-sep=N separate lines by char N (numerical ASCII code) (default="0x0a") --edit-frame-b=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 tool ;-) fix errors: --cut-junk-start remove junk before first frame --cut-junk-end remove junk after last frame --cut-tag-end remove trailing tag --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) --add-tag add ID3 v1.1 tag calculated from filename and path using simple heuristics if a file does not already have a tag disable error messages for -e --error-check: -G --ign-tag128 ignore 128 byte TAG after last frame -Y --ign-resync ignore synchronization errors (invalid frame header/frame too long/short) -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 appear to be 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,Mp3,mP3 --xdev do not descend into other filesystems when recursing directories --print-files just print all filenames without processing them, then exit (for debugging purposes, also useful to create files for --filelist) 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 replace the range of ASCII chars 160-255 (which is usually printable: e.g. ISO-8859) by '?' -p --progress show progress information on stderr -v --verbose be more verbose --no-mmap do not use mmap (e.g. when you get 'mmap: No such device') 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 mp3check version 0.8.7 *** (C) 1998-2003,2005,2008-2009,2012 by Johannes Overmann comments, bugs and suggestions welcome: Johannes.Overmann@gmx.de this program is distributed under the terms of the GNU General Public License version 2
