+.SH DESCRIPTION

+\fBaubionotes\fP attempts to detect notes by looking for note onsets and pitches.
+Consecutive events are segmented using onset detection, while a fundamental
+frequency extraction algorithm determines their pitch.
+.PP
+When started with an input \fIsource\fP (\fB-i\fP/\fB--input\fP), the detected notes are
+printed on standard output, in seconds and midi note number.
+.PP
+When started without an input \fIsource\fP, or with the jack option (\fB-j\fP/\fB--jack\fP),
+\fBaubionotes\fP starts in jack mode.

+.SH DESCRIPTION
+
+\fBaubioonset\fP attempts to detect onset times, the beginning of discrete sound
+events, in audio signals.
+.PP
+When started with an input \fIsource\fP (\fB-i\fP/\fB--input\fP), the detected onset times are
+given on the console, in seconds.
+.PP
+When started without an input \fIsource\fP, or with the jack option (\fB-j\fP/\fB--jack\fP),
+\fBaubioonset\fP starts in jack mode.
+.SH OPTIONS
+
+This program follows the usual GNU command line syntax, with long options
+starting with two dashes (--). A summary of options is included below.
+.TP
+.B
+\fB-i\fP, \fB--input\fP \fIsource\fP
+Run analysis on this audio file. Most uncompressed and
+compressed are supported, depending on how aubio was built.
+.TP
+.B
+\fB-o\fP, \fB--output\fP \fIsink\fP
+Save results in this file. The file will be created on
+the model of the input file. Onset times are marked by a short wood-block
+like sound.
+.TP
+.B
+\fB-r\fP, \fB--samplerate\fP \fIrate\fP
+Fetch the input \fIsource\fP, resampled at the given
+sampling \fIrate\fP. The \fIrate\fP should be specified in Hertz as an integer. If 0,
+the sampling \fIrate\fP of the original \fIsource\fP will be used. Defaults to 0.
+.TP
+.B
+\fB-B\fP, \fB--bufsize\fP \fIwin\fP
+The size of the buffer to analyze, that is the length
+of the window used for spectral and temporal computations. Defaults to 512.
+.TP
+.B
+\fB-H\fP, \fB--hopsize\fP \fIhop\fP
+The number of samples between two consecutive analysis.

+.TP
+.B
+\fB-t\fP, \fB--onset-threshold\fP \fIthres\fP
