aubiotrack

NAME

aubiotrack --- a command line tool for real time beat tracking

SYNOPSIS

aubiotrack [options] [-i soundfile]

DESCRIPTION

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.

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 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.

BUGS

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