AUBIOPITCH(1) General Commands Manual AUBIOPITCH(1) NAME
aubiopitch -- a command line tool to extract pitch candidates from sound files. SYNOPSIS
aubiopitch [options] -i soundfile DESCRIPTION
aubiopitch attempts to extract fundamental frequency in sound files. When no pitch candidate is found, the output is 0. Five fundamental frequency extraction methods are available. Results can be printed in Hertz or in MIDI pitch. 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 pitch_detection_mode pitch detection mode [default=mcomb] mcomb|yin|fcomb|schmitt -u --units unitmode output pitch in units [default=Hz] freq|midi|cent|bin -B --bufsize=BUFSIZE buffer size [default=1024] -H --hopsize=HOPSIZE overlap size [default=512] -t --threshold=THRESHOLD pitch threshold (for yin) [default=0.1] -s --silence=SILENCE silence threshold [default=-70] -D --delay=DELAY number of seconds to take back [default=0] -S --smoothing=frames temporal smoothing using a median filter of N frames [default=0] -M --pitchmax=max maximum pitch values to look for (Hz) [default=20000] -l --pitchmin=min minimum pitch values to look for (Hz) [default=20] -n --note NOT IMPLEMENTED output notes -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 of the pitch track -T --plottruth draw plot of the ground truth pitch track -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
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
