       aubiotrack — a command line tool for real time beat tracking


       aubiotrack [options] [-i soundfile]


       aubiotrack  attempts  to  tap  the  beat  and  detect beat locations in
       musical  sounds.  When  started  with  an  input  file  argument  (-i),
       aubiotrack print the beat locations in second detected in the file.

       When  started  without  an  input  file  argument (--input), aubiotrack
       creates jack input and output ports. When an input file is  given,  the
       results are given on the console.


       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
                 Run  analysis  on  this  audio file. Most common uncompressed
                 formats are supported.

       -o   --output fileout
                 Save results in this file. The file will be  created  on  the
                 model  of the input file. Results are marked by a short wood-
                 block sample.

       -O   --onset mode
                 The onset detection function to run. Available functions  are
                 complexdomain,  hfc,  phase, specdiff, energy, kl and mkl. By
                 default, both Kullback Liebler (kl) and  complex  domain  are
                 used in parallel.

       -t   --threshold value
                 Set  the  threshold value for the onset peak picking. Typical
                 values are within 0.001 and  0.900.  Default  is  0.1.  Lower
                 threshold  values imply more onsets detected. Try 0.3 in case
                 of over-detections.

       -j   --jack
                 Run in jack mode (default when started  without  input  file)
                 and creates a midi output.

       -v   --verbose
                 Show results on the console (default).

       -h   --help
                 Show summary of options.


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