NAME

       cutmp3 - a fast and leightweight mp3 editor

SYNOPSIS

       cutmp3  [-i  <file>]  [-O  <file>]  [-a <startpoint>] [-b <endpoint>] [-f <timetable>] [-o
       <output_prefix>] [-I <file> [-F]] [-d 2] [-s <factor>] -e -c -q

DESCRIPTION

       Cutmp3 is a small and fast command line MP3 editor. It lets you select sections of an  MP3
       interactively  or via a timetable and save them to separate files without quality loss. It
       uses mpg123 for playback and works with VBR files and even with  files  bigger  than  2GB.
       Other  features are configurable silence seeking and ID3 tag seeking, which are useful for
       concatenated mp3s.

OPTIONS

       -i <file>
              input file to edit

       -O <file>
              forced output filename

       -o <output_prefix>
              prefix of generated output filename
              (e.g. <output_prefix>0001.mp3, <output_prefix>0002.mp3, ...)

       -a <mm:ss.xx>
              starting position of selection to write to new file

       -b <mm:ss.xx>
              end position of selection to write to new file

       -f <timetable_file>
              use a timetable to extract several sequences from a given file.
              The timetable must have the following format:
              "<start_position> <end_position>" e.g.:

              0:01 1:00
              11:15 19:33
              01:01.34 02:39.78
              1:0 -0:05

              Negative values mean distance from the end of file.  Note that the options [-a] and
              [-b] override a given timetable.

       -e exact searching mode
              Switch on exact searching mode, useful for VBR files.
              Note that [-a] [-b] and [-f] use exact mode as default.

       -q quiet mode
              Switch  on  quiet  mode,  cutmp3  won't  make  any  sound, useful for debugging and
              commands using a pipe like: "echo 7a9bsq | cutmp3 -i file.mp3"

       -c copy metadata
              Copies metadata in non-interactive mode. Useful to keep ID3 tags when using  -a  -b
              or -f.

       -s maximum silence length factor
              Normally  cutmp3  stops  when the silence found is longer than 15 times the minimum
              silence length. [-s] changes this factor. 0 means infinity.

       -d 2   use the second soundcard (/dev/dsp1)

KEYBOARD CONTROL

       rewind with the following keys [1/2/3/4/5]
       move forward with the following keys [6/7/8/9/0]
       [0] means 10mins forward, [9] is 1min forward, [8] is 10secs forward, [7] is 1sec  forward
       and  [6]  is  1/10sec  forward. Keys [1] to [5] go symmetrically back (so [1] means 10mins
       back). For highest precision [,] goes back one frame and [.] goes one frame forward. After
       any of these keys you will hear the sound at this position for one second. When you are at
       the starting position of your part of interest, press the key [a]. When  you  are  at  the
       last  position  of  your part of interest, press the key [b] (What you hear after [b] will
       then be the last second inside the new file). By pressing [s] the resulting file  will  be
       written  to  result0001.mp3.  If  it  already  exists,  cutmp3 will increase the number to
       result0002.mp3, result0003.mp3 and so on.

       You can change the length of playback by pressing [N] and [M].

       You can seek to the end of the next  silence  by  pressing  [p]  (for  pause)  or  to  its
       beginning by pressing [P]. By default the silence should last for 1000 milliseconds, which
       is one second, and the maximum volume during this second is the minimum: 1 (whatever  that
       is in dB).

       You can change:

       - the length of the silence by pressing [n] or [m] and
       - the maximum volume during this silence by pressing [+] or [-].

       These values will be saved to ~/.cutmp3rc by pressing [S].

       You  can  seek  to  the  next  ID3 tag by pressing [T]. This is useful in case someone has
       merged several mp3s into one file without removing the ID3-tags.

       For other useful keycodes type [h] in interactive mode.

       Please note that cutmp3 only accepts one inputfile, so using wildcards like [?]  or [*] in
       filenames will result in editing only the first file that matches.

EXAMPLES

       1)  The resulting files will be written to blah0001.mp3, blah0002.mp3, blah0003.mp3 and so
       on:

           cutmp3 -i file.mp3 -o blah

       2) If you only want to cut a file once and you know the times for start and the  end,  you
       type:

           cutmp3 -i file.mp3 -a 0:37 -b 1:25

       and  cutmp3  will  write  the  passage  of file.mp3 starting at 0:37 and ending at 1:25 to
       blah01.mp3

       3) If you want to cut a file more often, you need  to  create  a  file  which  contains  a
       timetable and type (Please read README.timetable for details):

           cutmp3 -i file.mp3 -f name_of_the_timetablefile

       4)  Only  print  total  number  of frames, sampling frequency, number of channels, average
       bitrate, MPEG version and total time in milliseconds, in this order:

           cutmp3 -F -I file.mp3

       5) If you want to clean an MP3 from any data that is  not  sound,  just  use  (Cutting  in
       interactive mode does _not_ remove invalid data!):

           cutmp3 -i infile.mp3 -a 0:0 -b 99999:0
