       Aubio  currently  implements  one  the  causal  beat  tracking  algorithm  designed by Matthew Davies and
       described in the following articles:

       Matthew E. P. Davies and Mark D. Plumbley. Causal  tempo  tracking  of  audio.   In  Proceedings  of  the
       International Symposium on Music Information Retrieval (ISMIR), pages 164169, Barcelona, Spain, 2004.

       Matthew  E.  P.  Davies,  Paul  Brossier,  and  Mark D. Plumbley. Beat tracking towards automatic musical
       accompaniment. In Proceedings of the Audio Engineering Society 118th Convention,  Barcelona,  Spain,  May
       2005.

aubiotrack attempts to detect beats, the time where one would intuitively be tapping his foot.

       When started with an input source (-i/--input), the detected beats are given on the console, in seconds.

       When  started  without  an  input  source, or with the jack option (-j/--jack), aubiotrack starts in jack
       mode.

aubiotrack - a command line tool to extract musical beats from audio signals

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

       -i,--inputsource
              Run  analysis on this audio file. Most uncompressed and compressed are supported, depending on how
              aubio was built.

       -o,--outputsink
              Save results in this file. The file will be created on the model of  the  input  file.  Beats  are
              marked by a short wood-block like sound.

       -r,--sampleraterate
              Fetch  the  input  source,  resampled  at the given sampling rate. The rate should be specified in
              Hertz as an integer. If 0, the sampling rate of the original source will be used. Defaults to 0.

       -B,--bufsizewin
              The size of the buffer to analyze, that is the length of the window used for spectral and temporal
              computations. Defaults to 512.

       -H,--hopsizehop
              The number of samples between two consecutive analysis.  Defaults to 256.

       -s,--silencesil
              Set the silence threshold, in dB, under which the pitch will not be detected.  A  value  of  -20.0
              would  eliminate  most  onsets  but  the  loudest  ones. A value of -90.0 would select all onsets.
              Defaults to -90.0.

       -m,--mix-input
              Mix source signal to the output signal before writing to sink.

       -f,--force-overwrite
              Overwrite output file if it already exists.

       -j,--jack
              Use Jack input/output. You will need a Jack connection controller to feed aubio  some  signal  and
              listen to its output.

       -N,--miditap-note
              Override note value for MIDI tap. Defaults to 69.

       -V,--miditap-velop
              Override velocity value for MIDI tap. Defaults to 65.

       -T,--timeformatformat
              Set time format (samples, ms, seconds). Defaults to seconds.

       -h,--help
              Print a short help message and exit.

       -v,--verbose
              Be verbose.
