This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page. .PP .\" TeX users may be more comfortable with the \fB\fP and .\" \fI\fP escape sequences to invoke bold face and italics, .\" respectively. \fBmp3check\fP 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. \fBmp3check\fP 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. .SH 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. .TP \fBmode:\fP .TP .B \-l \-\-list list parameters by examining the first valid header and size .TP .B \-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) .TP .B \-e \-\-error-check check crc and headers for consistency and print several error messages .TP .B \-m \-\-max-errors= with \-e: set maximum number of errors to print per file (0==infinity) (range=[0..]) .TP .B \-a \-\-anomaly-check report all differences from these parameters: layer 3, 44.1kHz, 128kbps, joint stereo, no emphasis, has crc .TP .B \-d \-\-dump-header dump all possible header with sync=0xfff .TP .B \-t \-\-dump-tag dump all possible tags of known version .TP .B \-\-raw-list list parameters in raw output format for use with external programs .TP .B \-\-raw-elem-sep=NUM separate elements in one line by char NUM (numerical ASCII code) (default="0x09") .TP .B \-\-raw-line-sep=NUM separate lines by char NUM (numerical ASCII code) (default="0x0a") .TP .B \-\-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 ;-) .TP \fBfix errors:\fP .TP .B \-\-cut-junk-start remove junk before first frame .TP .B \-\-cut-junk-end remove junk after last frame .TP .B \-\-fix-headers fix invalid headers (prevent constant parameter switching), implies \-e, use with care .TP .B \-\-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) .TP \fBdisable error messages for \-e \-\-error\-check:\fP .TP .B \-G \-\-ign-tag128 ignore 128 byte TAG after last frame .TP .B \-R \-\-ign-resync ignore invalid frame header .TP .B \-E \-\-ign-junk-end ignore junk after last frame .TP .B \-Z \-\-ign-crc-error ignore crc errors .TP .B \-N \-\-ign-non-ampeg ignore non audio mpeg streams .TP .B \-T \-\-ign-truncated ignore truncated last frames .TP .B \-S \-\-ign-junk-start ignore junk before first frame .TP .B \-B \-\-ign-bitrate-sw ignore bitrate switching and enable VBR support .TP .B \-W \-\-ign-constant-sw ignore switching of constant parameters, such as sampling frequency .TP .B \-\-show\-valid print the message 'valid audio mpeg stream' for all files which error free (after ignoring errors) .TP \fBdisable anomaly messages for \-a \-\-anomaly\-check:\fP .TP .B \-C \-\-any-crc ignore crc anomalies .TP .B \-M \-\-any-mode ignore mode anomalies .TP .B \-L \-\-any-layer ignore layer anomalies .TP .B \-K \-\-any-bitrate ignore bitrate anomalies .TP .B \-I \-\-any-version ignore version anomalies .TP .B \-F \-\-any-sampling ignore sampling frequency anomalies .TP .B \-P \-\-any-emphasis ignore emphasis anomalies .TP \fBfile options:\fP .TP .B \-r \-\-recursive process any given directories recursively (the default is to ignore all directories specified on the command line) .TP .B \-f \-\-filelist=FILE process all files specified in FILE (one filename per line) in addition to the command line .TP .B \-A \-\-accept=LIST process only files with filename extensions specified by comma separated LIST .TP .B \-R \-\-reject=LIST do not process files with a filename extension specified by comma separated LIST .TP .B \-3 \-\-only-mp3 same as .B \-\-accept mp3,MP3 .TP .B \-\-xdev do not descend into other filesystems when recursing directories (doesn't work in Cygwin environment) .TP .B \-\-print\-files just print all filenames without processing them, then exit .TP \fBoutput options:\fP .TP .B \-s \-\-single-line print one line per file and message instead of splitting into several lines .TP .B \-\-no\-summary suppress the summary printed below all messages if multiple files are given .TP .B \-g \-\-log-file=FILE print names of erroneous files to FILE, one per line .TP .B \-q \-\-quiet quiet mode, hide messages about directories, non-regular or non-existing files .TP .B \-o \-\-color colorize output with ANSI sequences .TP .B \-b \-\-alt-color colorize: do not use bold ANSI sequences .TP .B \-\-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 '?' .TP .B \-p \-\-progress show progress information on stderr .TP \fBcommon options:\fB .TP .B \-0 \-\-dummy do not write/modify anything other than the logfile .TP .B \-h \-\-help print this help message, then exit successfully .TP .B \-\-version print version, then exit successfully .SH AUTHOR This original manual page was written by Klaus Kettner , for the Debian GNU/Linux system.
