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
