Onsets are used to label the beginning of notes, pitches to label their height.</para> <para><command>aubionotes</command> 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 (<option>-i</option>), aubionotes creates a jack input and a midi output. When an input file is given, it outputs the results on the console.</para> </refsect1> <refsect1> <title>OPTIONS</title> <para>This program follows the usual GNU command line syntax, with long options starting with two dashes (`-').
