This manual page documents briefly the aubioonset command.
The library aubio provides a small set of functions to extract events and objects from audio, from live streams or still files. Onsets are used to label the beginning of notes, pitches to label their height.
aubionotes is still in an experimental state. Its aim
is to segment notes with onsets, and label them with their detected pitch. When
started without an input file argument (
creates a jack input and a midi output. When an input file is given, it outputs
the results on the console.
This program follows the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below.
Run analysis on this audio file. Most common (uncompressed) formats are supported.
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.
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.
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.
Run in jack mode (default when started without input file) and creates a midi output.
