.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-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 set
to 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.
Defaults to 256.
.TP
.B
\fB-O\fP, \fB--onset\fP \fImethod\fP
The onset detection \fImethod\fP to use. See ONSET METHODS
below. Defaults to 'default'.
.TP
.B
\fB-b\fP, \fB--beat\fP
Use beat locations instead of onset locations.
.TP
.B
\fB-t\fP, \fB--onset-threshold\fP \fIthres\fP
Set the threshold value for the onset peak
picking. Values are typically in the range [0.001, 0.900]. Lower threshold
values imply more onsets detected. Increasing this threshold should reduce
the number of incorrect detections. Defaults to 0.3.
.TP
.B
\fB-c\fP, \fB--cut\fP
Cut input sound file at detected labels. A new sound files for
each slice will be created in the current directory.
.TP
.B
\fB-o\fP, \fB--output\fP directory
Specify the directory path where slices of the
original \fIsource\fP should be created.
.TP
.B
\fB--cut-until-nsamples\fP n
How many extra samples should be added at the end of
each slice (default 0).
.TP
.B
\fB--cut-until-nslices\fP n
How many extra slices should be added at the end of
each slice (default 0).
.TP
.B
\fB--create-first\fP
Alway create first slice.
.TP
.B
\fB-h\fP, \fB--help\fP
Print a short help message and exit.
.TP
.B
\fB-v\fP, \fB--verbose\fP
Be verbose.
.TP
.B
\fB-q\fP, \fB--quiet\fP
Be quiet.
