NAME
aubiocut - a command line tool to slice sound files at onset or beat timestamps
SYNOPSIS
aubiocut source
aubiocut [[-i] source]
[-r rate] [-B win] [-H hop]
[-O method] [-t thres]
[-b] [-c]
[-v] [-q] [-h]
OPTIONS
This program follows the usual GNU command line syntax, with long options
starting with two dashes (--). A summary of options is included below.
-i, --input source Run analysis on this audio file. Most uncompressed and
compressed are supported, depending on how aubio was built.
-r, --samplerate rate Fetch the input source, resampled at the given
sampling rate. The rate should be specified in Hertz as an integer. If set
to 0, the sampling rate of the original source will be used. Defaults to 0.
-B, --bufsize win The size of the buffer to analyze, that is the length
of the window used for spectral and temporal computations. Defaults to 512.
-H, --hopsize hop The number of samples between two consecutive analysis.
Defaults to 256.
-O, --onset method The onset detection method to use. See ONSET METHODS
below. Defaults to 'default'.
-b, --beat Use beat locations instead of onset locations.
-t, --onset-threshold thres 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.
-c, --cut Cut input sound file at detected labels. A new sound files for
each slice will be created in the current directory.
-o, --output directory Specify the directory path where slices of the
original source should be created.
--cut-until-nsamples n How many extra samples should be added at the end of
each slice (default 0).
--cut-until-nslices n How many extra slices should be added at the end of
each slice (default 0).
--create-first Alway create first slice.
-h, --help Print a short help message and exit.
-v, --verbose Be verbose.
-q, --quiet Be quiet.
ONSET METHODS

specflux.
