PROGRAM:
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]
[-s sil] [-m]
[-j] [-v] [-h]
DESCRIPTION
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.
OPTIONS
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 source
Run analysis on this audio file. Most uncompressed and compressed 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. Defaults 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. 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.
-h, --help
Print a short help message and exit.
-v, --verbose
Be verbose.
