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.
