AUBIONOTES

Name

aubionotes -- a command line tool for real time wav to midi conversion

Synopsis

aubionotes

DESCRIPTION

This manual page documents briefly the aubionotes command.

aubionotes is still in an experimental state. Its aim is to extract the melody and output it as a midi stream with a minimal deleay. Pitch candidates are selected at each frame, onset and silences are used to segment the notes.

When started without an input file argument (-i), aubionotes creates a jack input and a midi output. When an input file is given, it outputs the results 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 very short wood-block sample.

-P --pitch mode

The pitch detection function to run. Available functions are mcomb, yin, 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. The lower the more sensible. 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.

-h --help

Show summary of options.

-v --verbose

Show results on the console.

BUGS

For now the program has been only tested on audio signals sampled at 44.1 kHz. The pitch detectors are also way too cpu-intensive.
