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.

RUBBERBAND(1) General Commands Manual RUBBERBAND(1)NAME
rubberband -- an audio time-stretching and pitch-shifting utility program
SYNOPSIS
rubberband [options] [input file] [output file]
DESCRIPTION
This manual page documents briefly the rubberband command.
Rubber Band is a program that permits you to change the tempo and pitch of an audio recording independently of one another.
OPTIONS
These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is
included below.
You must specify at least one of the following time and pitch ratio options.
-t, --time X
Stretch to X times original duration, or
-T, --tempo X
Change tempo by multiple X (equivalent to --time 1/X)
-p, --pitch X
Raise pitch by X semitones, or
-f, --frequency X
Change frequency by multiple X
The following option provides a simple way to adjust the sound. See below for more details.
-n, --crisp N
Crispness (N = 0,1,2,3,4,5); default 4 (see below)
The remaining options fine-tune the processing mode and stretch algorithm. These are mostly included for test purposes; the default set-
tings and standard crispness parameter are intended to provide the best sounding set of options for most situations.
-P, --precise
Aim for minimal time distortion (implied by -R)
-R, --realtime
Select realtime mode (implies -P --no-threads)
--no-threads
No extra threads regardless of CPU and channel count
--threads Assume multi-CPU even if only one CPU is identified
--no-transients
Disable phase resynchronisation at transients
--bl-transients
Band-limit phase resync to extreme frequencies
--no-peaklock
Disable phase locking to peak frequencies
--no-softening
Disable large-ratio softening of phase locking
--window-long
Use longer processing window (actual size may vary)
--window-short
Use shorter processing window
--thresh N F
Set internal freq threshold N (N = 0,1,2) to F Hz
-d, --debug N
Select debug level (N = 0,1,2,3); default 0, full 3 (N.B. debug level 3 includes audible ticks in output)
-q, --quiet
Suppress progress output
-h, --help
Show a list of available options
"Crispness" levels:
0 equivalent to --no-transients --no-peaklock --window-long
1 equivalent to --no-transients --no-peaklock
2 equivalent to --no-transients
3 equivalent to --bl-transients
4 default processing options
5 equivalent to --no-peaklock --window-short (may be suitable for drums)
