rbpitch

rbpitch is a plugin for Rhythmbox which allows the user to change the pitch, tempo, and speed of the music playback.

rbpitch is a plugin for Rhythmbox that lets you change the pitch, tempo, and speed in real-time while playing a song. The main features of rbpitch include:

*Change the pitch and tempo of your music independently of each other.
*Change the "speed", which is pitch+tempo scaled together without aliasing.
*Remember pitch and tempo settings between launches.
*Easy to use GUI, integrated into the Rhythmbox shell.

There are other programs similar to rbpitch. rbpitch closely resembles:
*PaceMaker: http://surina.net/pacemaker/ (closed source, Windows only)
*J. River Media Jukebox 12 contains similar functionality (closed source, Windows only)
*foo_dsp_soundtouch for Foobar2000 (closed source, Windows only)
*scaletempo for Rhythmbox: http://willem.engen.nl/projects/musictools/ (open source, cross platform)

Here are some possible uses of rbpitch, borrowed from http://surina.net/pacemaker by Olli Parviainen (with permission):
*Slower music tempo eases practicing music
*Change the music key to match the singer's voice (karaoke, singing practice)
*Dancers can change the music tempo suitable for dancing
*Adjust music key instead of retuning instrument for each song
*Listen 78 RPM vinyl singles with a usual 33/45 RPM disc player
*Transcribe tunes
*Write down dictations

What is new in this release:

• rbpitch for Rhythmbox 2.96 and 2.97 has been released, for Precise and Quantal (Ubuntu 12.04 and 12.10). Go forth and test! Instructions are to just install the "rbpitch" package from the PPA.

What is new in version 0.13.1:

• This is a special release: I have given up on trying to ship the Vala-based plugin to the masses. However, I don't have to rewrite rbpitch to ship something that almost everyone who uses Rhythmbox 0.13.0 or later should be able to do: compile an out-of-tree C plugin. That, at least, is supported. And Vala compiles down to C code. Do you see where this is going?

Requirements:

• Rhythmbox
