.TH "AUBIOCUT" "1" 
.SH "NAME" 
aubiocut \(em a command line tool to extract onsets and tempo from sound files. 
.SH "SYNOPSIS" 
.PP 
\fBaubiocut \fB[options] \-i soundfile\fR\fR 
.SH "DESCRIPTION" 
.PP 
\fBaubiocut\fR attempts to detect onset times, the 
beginning of discreted sound events, or beat locations, in audio 
signals. 
.PP 
When using the \fB\-\-cut\fP option, 
\fBaubiocut\fR takes an input sound file and produce small 
files sliced at onset locations (or silences). The slices can then be sent 
for example to a player, a sequencer, or a sampler. 
.PP 
A plotting module is available via the Gnuplot Python package. 
.SH "OPTIONS" 
.PP

options starting with two dashes (`\-').  A summary of options is included 
below.

.IP "\fB-D\fP   \fB\-\-delay=DELAY\fP" 10 
number of seconds to take back [default=system] 
default system delay is 3*hopsize/samplerate 
.IP "\fB-L\fP   \fB\-\-localmin\fP" 10 
use local minima after peak detection 
.IP "\fB-c\fP   \fB\-\-cut\fP" 10 
cut input sound file at detected labels (best used with option \-L) 
.IP "\fB-d\fP   \fB\-\-derivate\fP" 10 
derivate onset detection function 
.IP "\fB-S\fP   \fB\-\-silencecut\fP" 10 
outputs silence locations instead of onset locations 
.IP "\fB-z\fP   \fB\-\-zerocross=ZEROTHRES\fP" 10 
zero-crossing threshold for slicing [default=0.00008] 
.IP "\fB-f\fP   \fB\-\-function\fP" 10 
print detection function 
.IP "\fB-q\fP   \fB\-\-quiet\fP" 10

.SS "Plotting options" 
.PP 
When the Python interface to Gnuplot is installed, the following 
additional options are available. 
.IP "\fB-p\fP   \fB\-\-plot\fP" 10 
draw plot 
.IP "\fB-n\fP   \fB\-\-no-onsets\fP" 10 
do not plot detected onsets, only detection functions 
.IP "\fB-x\fP   \fB\-\-xsize=SIZE\fP" 10 
define horizontal plot size [default=1.] 
.IP "\fB-y\fP   \fB\-\-ysize=SIZE\fP" 10 
define vertical plot size [default=1.] 
.IP "\fB-O\fP   \fB\-\-outplot=OUTPLOT\fP" 10 
save plot to output.{ps,eps,png,svg} instead of displaying it 
.SH "BUGS" 
.PP 
For now the program has only been tested on audio signals sampled at 
44.1\ kHz.
