aubioonset — a command line tool for real time onset extraction
aubioonset [options] [-i soundfile]
aubioonset attempts to detect onset times, the beginning of discreted sound events, in audio signals. When started without an input file argument (--input), aubioonset creates jack input and output ports. When an input file is given, the results are given on the console.
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 filein Run analysis on this audio file. Most common uncompressed formats are supported. -o --output fileout Save results in this file. The file will be created on the model of the input file. Results are marked by a short wood-block sample. -O --onset mode The onset detection function to run. Available functions are complexdomain, hfc, phase, specdiff, energy, kl and mkl. By default, both Kullback Liebler (kl) and complex domain are used in parallel. -t --threshold value Set the threshold value for the onset peak picking. Typical values are within 0.001 and 0.900. Default is 0.1. Lower threshold values imply more onsets detected. Try 0.3 in case of over-detections. -j --jack Run in jack mode (default when started without input file) and creates a midi output. -v --verbose Show results on the console (default). -h --help Show summary of options.
For now the program has only been tested on audio signals sampled at 44.1 kHz.
