Checkmate MP3 Checker is a free program that checks MP3 files for errors. It scans MP3 files to see if the frames are where they are supposed to be, whether the frame headers are correct and whether the frame headers are consistent throughout the file. It reports some information on each file and an indication whether the file is good or bad.
There are two interfaces available:
- Checkmate MP3 Checker, a Windows interface that looks like Windows Explorer;
- mpck, a command line program that runs on multiple platforms.
Checkmate MP3 Checker is a Windows interface to check MP3 files:
You can download the Windows executable on the releases page.
Example:
$ mpck '001 Katy Perry - Dark Horse (feat. Juicy J).mp3'
SUMMARY: 001 Katy Perry - Dark Horse (feat. Juicy J).mp3
version MPEG v1.0
layer 3
bitrate 320000 bps
samplerate 44100 Hz
frames 8250
time 3:35.510
unidentified 0 b (0%)
errors none
result Ok
If your release does not have configure, first run
./autogen.sh
After that, it is the normal build method:
./configure
make
make install
For Windows there is a Visual Studio project in the vc directory.
Usage: mpck [OPTION]... [FILE]...
Verbosity:
-v, --verbose print some extra info
-q, --quiet print only Ok or Bad per file
-B, --badonly only report bad files
Other options:
-R, --recursive check directories recursively
-e, --extention=EXT only check files ending on .EXT
-r short for -R -e mp3
-m, --maxname=NUM report bad for filenames which exceed NUM characters
-n, --namecheck check for strange characters in the filename
-x, --xmloutput output results in XML
-h, --help print this help, then exit
-V, --version print version information
If all is well, mpck will output something like this:
SUMMARY: mp3/test.mp3
version MPEG v1.0
layer 3
bitrate 128000 bps
samplerate 44100 Hz
frames 7271
time 3:09.936
unidentified 0 b (0%)
errors none
result Ok
Occasionally, something goes wrong and mpck prints an error. It has one of the following formats:
- mpck: stat on blah failed
- mpck:bla: foo bar error
- mpck:bla:34003: yet another error
Number 1 indicates a general error. Number 2 means an error occured in file bla. Number 3 says an error occured in file bla, at offset 34003 (decimal).
mpck returns one of the following values:
0 Everything went OK and no broken files were found.
1 Everything went OK, but at least one broken file was found.
2 (ENOENT) File or directory not found, stat failed.
4 (EINTR) The program received a SIGINT.
5 (EIO) Read error.
12 (ENOMEM) Malloc failed due to memory shortage.
21 (EISDIR) The given file is a directory.
22 (EINVAL) Invalid argument, no filename supplied.
36 (ENAMETOOLONG) File extention or file name is too long.
