AUBIOCUT(1) General Commands Manual AUBIOCUT(1)NAMEaubiocut -- a command line tool to extract onsets and tempo from sound files.SYNOPSISaubiocut [options] -i soundfileDESCRIPTIONaubiocut 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.OPTIONSThis 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 itBUGSFor now the program has only been tested on audio signals sampled at 44.1 kHz.SEE ALSOaubioonset(1) aubiotrack(1) aubionotes(1) aubiopitch(1)AUTHORThis manual page was written by Paul Brossier (piem@altern.org).
