AUBIOTRACK(1) General Commands Manual AUBIOTRACK(1) NAME
aubiotrack -- a command line tool for real time beat tracking SYNOPSIS
aubiotrack [options] [-i soundfile] DESCRIPTION
aubiotrack attempts to tap the beat and detect beat locations in musical sounds. When started with an input file argument (-i), aubiotrack print the beat locations in second detected in the file. When started without an input file argument (--input), aubiotrack creates jack input and output ports. When an input file is given, the results are given on the console. 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 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 sam- ple. -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. BUGS
For now the program has only been tested on audio signals sampled at 44.1 kHz. SEE ALSO

AUBIOCUT(1) General Commands Manual AUBIOCUT(1) NAME
aubiocut -- a command line tool to extract onsets and tempo from sound files. SYNOPSIS
aubiocut [options] -i soundfile DESCRIPTION
aubiocut attempts to detect onset times, the beginning of discreted sound events, or beat locations, in audio signals. When using the --cut option, aubiocut takes an input sound file and produce small files sliced at onset locations (or silences). The slices can then be sent for example to a player, a sequencer, or a sampler. A plotting module is available via the Gnuplot Python package. 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 filein input sound file -m --mode onset_detection_mode onset detection mode [default=dual] complexdomain|hfc|phase|specdiff|energy|kl|mkl|dual -b --beat detect beats and output beat locations -B --bufsize=BUFSIZE buffer size [default=512] -H --hopsize=HOPSIZE overlap size [default=256] -t --threshold=THRESHOLD onset peak picking threshold [default=0.3] -C --dcthreshold=DCTHRESHOLD onset peak picking DC component [default=1.] -s --silence=SILENCE silence threshold [default=-70] -M --mintol=MINIOI minimum inter onset interval [default=0.048s] -D --delay=DELAY number of seconds to take back [default=system] default system delay is 3*hopsize/samplerate -L --localmin use local minima after peak detection -c --cut cut input sound file at detected labels (best used with option -L) -d --derivate derivate onset detection function -S --silencecut outputs silence locations instead of onset locations -z --zerocross=ZEROTHRES zero-crossing threshold for slicing [default=0.00008] -f --function print detection function -q --quiet be quiet -h --help Show a summary of options. -v --verbose make lots of noise [default] Plotting options When the Python interface to Gnuplot is installed, the following additional options are available. -p --plot draw plot -n --no-onsets do not plot detected onsets, only detection functions -x --xsize=SIZE define horizontal plot size [default=1.] -y --ysize=SIZE define vertical plot size [default=1.] -O --outplot=OUTPLOT save plot to output.{ps,eps,png,svg} instead of displaying it BUGS
