NAME¶
aubioonset — a command line tool for real time onset extraction
SYNOPSIS¶
aubioonset [options] [-i soundfile]
DESCRIPTION¶
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.
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.
