aubiocut - Man Page

a command line tool to slice sound files at onset or beat timestamps


aubiocut source
aubiocut [[-i] source]
         [-r rate] [-B win] [-H hop]
         [-O method] [-t thres]
         [-b] [-c]
         [-v] [-q] [-h]


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).


Alway create first slice.

-h,  --help

Print a short help message and exit.

-v,  --verbose

Be verbose.

-q,  --quiet

Be quiet.
