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 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. Typical values are typically within 0.001 and 0.900. Defaults to 0.1. Lower threshold values imply more onsets detected. Try 0.5 in case of over-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.
-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.
