PROGRAM:

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 settings 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)
