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
-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-
-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
Run in jack mode (default when started without input file)
and creates a midi output.
Show results on the console (default).
Show summary of options.
For now the program has only been tested on audio signals sampled at
