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.
