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

SYNOPSIS
       aubiotrack source
       aubiotrack [[-i]	source]	[-o sink]
		  [-r rate] [-B	win] [-H hop]
		  [-T time-format]
		  [-s sil] [-m]
		  [-j] [-N miditap-note] [-V miditap-velo]
		  [-v] [-h]

DESCRIPTION
       aubiotrack attempts to detect beats, the	time  where  one  would	 intu-
       itively 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.

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

       -i, --input source
	      Run  analysis  on	 this  audio  file. Most uncompressed and com-
	      pressed are supported, depending on how aubio was	built.

       -o, --output sink
	      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, --samplerate	rate
	      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, --bufsize win
	      The  size	 of  the  buffer to analyze, that is the length	of the
	      window used for spectral and temporal computations. Defaults  to
	      512.

       -H, --hopsize hop
	      The  number  of  samples	between	two consecutive	analysis.  De-
	      faults to	256.

       -s, --silence sil
	      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.  De-
	      faults 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 con-
	      troller 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, --timeformat	format
	      Set time format (samples,	ms, seconds). Defaults to seconds.

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

       -v, --verbose
	      Be verbose.

BEAT TRACKING METHODS
       Aubio currently implements one the causal beat tracking	algorithm  de-
       signed by Matthew Davies	and described in the following articles:

       dio.  In	Proceedings of the International Symposium on  Music  Informa-
       tion Retrieval (ISMIR), pages 164A169, Barcelona, Spain,	2004.
