mp3burn1

Usage

Overview

mp3burn is a simple command line tool for making audio CDs from MP3s without filling up your disk with .wav files. It uses Perl(1), ogg123(1), mpg321(1) or mpg123(1), cdrecord(1), flac(1), and the MP3::Info(3) Perl module.

Options

-h, --help

Prints out a brief help

-m, --swap

Manual "cdrecord -swab" option mode. Use this to disable the automatic detection for swab mode in case it is not working correctly on your system. (Also, please send email to <[email protected]> or file a bug against the mp3burn package if you encounter this problem.)

-p, --playlist ".m3u playlist"

Use a playlist to specify audio files to burn. Instead of (or in addition to) listing mp3/ogg/flac files, supply a .m3u playlist (e.g., from xmms) that contains the audio files for your CD.

Note: If you specify both a playlist and audio files, the files specified on the command-line will be appended to the list of audio files listed in the playlist. If a file referenced in a playlist cannot be read, it will be skipped. Be wary of playlist editors that use relative paths - mp3burn cannot know what path the playlist editor assumed.

-t, --tmpdir "tmpdir"

Put temporary files in tmpdir. Default is to use the current directory.

-c, --check "MMM:SS" | ATIP

Time check: compute the total length of files to be burned and warn if greater than MMM:SS minutes and seconds. If the value ATIP is supplied, the total length is checked against the length available on the CDR[W] as reported by ATIP.

Note that FLAC-encoded files are assumed to be 1 second long (until there is an easy way to get the file duration). You will need to calculate burn-length on your own with FLAC files.

-d, --dummy

Perform a "dummy" run: do everything except actually burn the CD (uses cdrecord(1) "-dummy" option).

-o, --cdrecord "cdrecord_opts"

Specify the command line options for cdrecord. The quotes are required to prevent mp3burn from parsing cdrecord(1) options. Overrides options specified in ~/.mp3burnrc.

Example: -o "-v dev=1,0 speed=4 -swab"

Note:

The options -pad and -audio are added automatically, since they are always necessary. The script also tries to detect if -swab is needed (for example on x86 and other little-Endian platforms). cdrecord is supposed to take care of any byte-ordering requirements specific to your burner. (If you end up with a CD that merely sounds like static, you most likely need to toggle use of -swab.) You should also consider using -v so that you can watch the burn in progress. This goes for ~/.mp3burnrc also.

-a, --atip

Lookup the ATIP info for the device in the cdburner (using cdrecord(1) "-atip") and then exits. This option can only be used (successfully) in conjuction with -o.

-M, --encoder "MP3 decoder"

Use an MP3 decoder other than the default, which is mpg321. This is imperative when burning tracks that have sample rates other than 44.1kHz, and the current version of mpg321 will not decode these files. Specify the name of the decoder to be used, e.g. mpg123-oss-3dnow; you can also specify this in your .mp3burnrc file with $mp3decoder = mp3decoder. (Note: Currently, the MP3 decoder must be able to accept mpg123-style command-line arguments.)

Return value

mp3burn returns 0 on success.

Diagnostics

Error in .mp3burnrc:

Perl(1) cannot parse the .mp3burnrc file. The following example occurs when a double quote is not terminated:

  bash-2.05$ sudo mp3burn -d ~/bell.ogg 
  String found where operator expected at (eval 10) line 7, at end of line
          (Missing operator before ?)
  Error in .mp3burnrc:
  Can't find string terminator '"' anywhere before EOF at (eval 10) line 7.
  bash-2.05$

You will experience this error if you define both $cdrecord_opts and $mp3decoder without terminating the variable assignments with the ';' character:

  $ mp3burn -d -t /tmp Theodor_Storm_Aquis_submersus_1.mp3 
  Scalar found where operator expected at (eval 10) line 2, near ""-v speed=2 dev=0,3,0"
  $mp3decoder"
        (Missing operator before 
  $mp3decoder?)
  Error in .mp3burnrc:
  syntax error at (eval 10) line 2, near ""-v speed=2 dev=0,3,0"
  $mp3decoder"

Examples

Write an Ogg Vorbis file from a CD-R drive, /dev/scd0, mounted at /mnt/scd0/ to a CD-RW drive, /dev/scd1, called "0,1,0" in cdrecord(1) SCSI notation. Ensure that file is no longer than 50 minutes. sudo(1) is used to get root permissions for cdrecord(1).

  % sudo mp3burn -c 050:00 -o "-v speed=2 dev=0,1,0" /mnt/scd0/bell.ogg

Create a ~/.mp3burnrc that prints a message before writing and uses a different MP3 decoder than the default of mpg321.

  # This is an example.
  $cdrecord_opts="-v speed=2 dev=0,1,0";
  $mp3decoder = "mpg123-oss-3dnow";
  print "Nine seconds to slap a CD-R in the drive!\n" ;
  #
  # See mp3burn(3).
  #

Specify an mp3decoder other than mpg321.

  $ sudo mp3burn -M mpg123-esd ./rush/*mp3

Files

~/.mp3burnrc

In this file, you may permanently specify the cdrecord options and MP3 decoder you want to use. The format is:

  $cdrecord_opts = "cdrecord options";
  $mp3decoder = "some mp3 decoder";

You may place comments in this file by beginning a line with "#".

Note:

The values of $cdrecord_opts and $mp3decoder in ~/.mp3burnrc are ignored if the "-o" or "-<"command-line options are used, respectively.

Caveats

Has not been tested extensively with Ogg Vorbis files. Ogg Vorbis files must be in CD-DA format: i.e. 44100 samples/channel x 16 bits/sample x 2 channels.

Notes

There are a number of GUI frontends for mp3burn:
