aubionotes — a command line tool for real time extraction of musical
aubionotes [options] [-i soundfile]
aubionotes attempts to detect notes in audio signals, segmenting
consecutive events using onset detection, and determining their pitch
using a fundamental frequency extraction algorithm.
When started without an input file argument (--input), aubionotes
creates a jack input and a MIDI output. 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-
-P --pitch mode
The pitch detection function to run. Available functions are
yinfft, yin, mcomb, fcomb, and schmitt.
-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
