     page: `docbook-to-man manpage.sgml > manpage.1'.  You may view
     the manual page with: `docbook-to-man manpage.sgml | nroff -man |

        debian/rules file targets (such as build), you will need to include
        docbook-to-man in your Build-Depends control field.

    <title>DESCRIPTION</title>

    <para>This manual page documents briefly the <command>&dhpackage;</command> command.</para>

    <para>The <emphasis>aubio</emphasis> library 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.</para>

    <para><command>&dhpackage;</command> attempts to extract fundamental
    frequency in sound files. When no pitch candidate is found, the output is
    0. Five fundamental frequency extraction methods are available. Results can
    be printed in Hertz or in MIDI pitch.</para>

    <para>A plotting module is available via the Gnuplot Python package.</para>
