       aubiocut — a command line tool to extract onsets and tempo from sound files.


       aubiocut [options] -i soundfile


       aubiocut  attempts to detect onset times, the beginning of discreted sound events, or beat
       locations, in audio signals.

       When using the --cut option, aubiocut takes an input sound file and  produce  small  files
       sliced  at  onset  locations  (or  silences). The slices can then be sent for example to a
       player, a sequencer, or a sampler.

       A plotting module is available via the Gnuplot Python package.


       This program follows the usual GNU command line syntax, with long  options  starting  with
       two dashes (`-').  A summary of options is included below.

       -i   --input filein
                 input sound file

       -m   --mode onset_detection_mode
                 onset                detection                mode                [default=dual]

       -b   --beat
                 detect beats and output beat locations

       -B   --bufsize=BUFSIZE
                 buffer size [default=512]

       -H   --hopsize=HOPSIZE
                 overlap size [default=256]

       -t   --threshold=THRESHOLD
                 onset peak picking threshold [default=0.3]

       -C   --dcthreshold=DCTHRESHOLD
                 onset peak picking DC component [default=1.]

       -s   --silence=SILENCE
                 silence threshold [default=-70]

       -M   --mintol=MINIOI
                 minimum inter onset interval [default=0.048s]

       -D   --delay=DELAY
                 number of  seconds  to  take  back  [default=system]  default  system  delay  is

       -L   --localmin
                 use local minima after peak detection

       -c   --cut
                 cut input sound file at detected labels (best used with option -L)

       -d   --derivate
                 derivate onset detection function

       -S   --silencecut
                 outputs silence locations instead of onset locations

       -z   --zerocross=ZEROTHRES
                 zero-crossing threshold for slicing [default=0.00008]

       -f   --function
                 print detection function

       -q   --quiet
                 be quiet

       -h   --help
                 Show a summary of options.

       -v   --verbose
                 make lots of noise [default]

   Plotting options
       When  the  Python  interface to Gnuplot is installed, the following additional options are

       -p   --plot
                 draw plot

       -n   --no-onsets
                 do not plot detected onsets, only detection functions

       -x   --xsize=SIZE
                 define horizontal plot size [default=1.]

       -y   --ysize=SIZE
                 define vertical plot size [default=1.]

       -O   --outplot=OUTPLOT
                 save plot to output.{ps,eps,png,svg} instead of displaying it


       For now the program has only been tested on audio signals sampled at 44.1 kHz.
