       aubioonset — a command line tool for real time onset extraction


       aubioonset [options] [-i soundfile]


       aubioonset  attempts  to  detect  onset times, the beginning of discreted sound events, in
       audio signals.

       When started without an input file argument (--input), aubioonset 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

       -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.
