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.


Available methods: default, energy, hfc, complex, phase, specdiff, kl, mkl, specflux.
