Installed Programs:
rubberband and rubberband-r3 (duplicate of rubberband)
Installed Libraries:
librubberband
Installed Directories:
/usr/include/rubberband
The rubberband package contains libraries and utilities that can effectively stretch audio time-wise and modify the pitch of a given audio file. This can be really useful when editing videos through something like kdenlive, but can also be used in other software such as FFmpeg. You will have to recompile the software that can use it and may have to add options to those packages to enable rubberband support.
In the case of kdenlive, it depends on
MLT for effects. As
such, you don't need to recompile kdenlive, but you must recompile MLT
without the -D MOD_RUBBERBAND=OFF parameter.
boost, fftw, OpenJDK, LADSPA-SDK-1.17, lv2, libsamplerate, Speex, and vamp-plugin-sdk
libsamplerate and Speex can be used as resamplers instead of the built-in implementation. Check “Command Explanations” for more information.
Install rubberband by running the following commands:
mkdir build &&
cd build &&
meson setup --prefix=/usr \
--buildtype=release \
-D default_library=shared \
.. &&
ninjaTo test the results, issue: ninja test
Now, as the root user:
ninja install
--buildtype=release: Specify a buildtype
suitable for stable releases of the package, as the default may
produce unoptimized binaries.
-D default_library=shared=: This parameter
tells the build system to only install shared libraries instead of
static libraries. By default, both types will be installed.
-D resampler=...: This option can be used to specify the
resampler to use. By default, it will use the built-in implementation.
You can specify libsamplerate, speex,
or speexdsp to override the default. If you are going
to do this, it is recommended to use libsamplerate.
