rubberband: update to 3.1.2.
Changes in Rubber Band v3.1.2
This minor release contains a small number of build fixes.
* Make all optional targets manually toggleable, using Meson
"features" options (see COMPILING.md for documentation)
* Further fix to JNI autodetection, following that of 3.1.1 -
hopefully solving the problem completely this time!
* Correct the source file listing in the Android makefile
* Fix build with NO_EXCEPTIONS, e.g. for Android
* Fix required #includes for mingw32 builds
The API is unchanged from 3.0 and the library is binary compatible
back to version 1.7.
Changes in Rubber Band v3.1.1
This minor release contains no code changes, only a fix to the build
system.
* Fix failure to configure and build on some systems without a Java
compiler. Java/JNI support is entirely optional in Rubber Band, but
auto-detection of whether to build it or not was failing in certain
environments: this broke the normal build process for some users.
The API is unchanged from 3.0 and the library is binary compatible
back to version 1.7.
Changes in Rubber Band v3.1
This significant release contains many enhancements that can improve
performance, as well as a number of bug fixes.
* Add support for "short window" mode, OptionWindowShort, to the new
R3 processing engine. This option previously only took effect with
the R2 engine. When used with R3 it disables the R3 multi-window
logic while retaining R3's signal analysis, yielding output with
some of the quality advantages of R3 (especially for non-percussive
content) but with far lower CPU usage and processing delay.
* Implement OptionPitchHighSpeed in the R3 engine. Previously it
always used OptionPitchHighConsistency internally. With this option
real-time pitch-shifting upwards becomes much faster, at the
expense of some output quality. (However OptionPitchHighConsistency
is still always necessary to avoid artifacts when performing
dynamic pitch changes.)
* Add support for the SLEEF library (libsleefdft) for FFTs. In
our tests this library approaches the performance of vDSP and IPP
and improves on the other supported options.
* Add support for external Speex library (libspeexdsp) for
resampling. This is a very fast resampler, significantly improved
over the older Speex code that has historically been bundled with
Rubber Band. It may still introduce a little more audible noise on
ratio changes than the built-in resampler.
* Update the R2 engine so that it always restores vertical phase
coherence gradually when returning to a ratio of 1.0 (as R3 also
does) rather than waiting for silence or a transient.
* Update R3 to properly support all sample rates between 8000 and
192000 Hz.
* Update command-line utility so as to use the extension of the
output filename to determine the file type to write. Previously
the output was always the same format as the input file,
regardless of extension.
* Remove support for libresample. This integration has not been
exercised in many years and other resamplers are better options.
* Fix several bugs, including a crash when run with very low sample
rates.
The API is unchanged from 3.0 and the library is binary compatible
back to version 1.7.
Changes in Rubber Band v3.0.0
* Introduce a new processing engine, the R3 (Finer) engine, which
typically produces higher-quality output than the existing R2
engine, though at significantly higher CPU cost. The R2 engine is
still the default, and R3 can be selected using the new
OptionEngineFiner option on construction. See the documentation for
more details.
* Add ability to provide a custom set of log callbacks, so that
debug and warning logs can be routed to the application's log
stream and/or handled in a realtime-safe way
* Add option to shift formant independently of pitch (R3 engine
only)
* Deprecate the rather ambiguous function getLatency(), effectively
replacing it with two new functions getPreferredStartPad() and
getStartDelay(). See their documentation for more details
The library is both binary and API compatible all the way back to the
1.x series for existing applications. Code written to use 3.0 is not
necessarily compatible with 2.x or 1.x, as several new functions and
enum values have been added, but code written to use any earlier
version can update to 3.0 without modification (and will continue to
use the same processing engine if the calling code is unchanged).
Changes in Rubber Band v2.0.2
* Fix a crash in certain configurations when using mid-side
processing (OptionChannelsTogether) with pitch shifts
* Fix failure to build on very old macOS versions (<= 10.8) when
combined with much newer compilers
The API is unchanged and the library is binary compatible back to
version 1.7.
Changes in Rubber Band v2.0.1
* Add a preliminary LV2 version of the example pitch-shifter plugin,
and update the existing LADSPA version to fix failure of the wet/dry
control to work correctly under in-place use
* Make the built-in resampler (introduced in v2.0.0) the default for
all builds, and use it in the official packaged versions of the
command-line utility. External resampler libraries are still
available as build options
* A couple of build fixes, including supporting the proper Meson
option (default_library=shared/static/both) at configuration time
to choose which type of library to build, instead of the custom
option used since v1.9.1
The API is unchanged and the library is binary compatible back to
version 1.7.
Changes in Rubber Band v2.0.0
* Introduce a built-in resampler, intended to minimise artifacts on
pitch changes and to allow Rubber Band to be compiled without any
external dependencies (when also using the built-in FFT). The
built-in resampler is newer and less well-tested than
libsamplerate, and is not yet the default except in no-dependency
builds
* Introduce single compilation unit single/RubberBandSingle.cpp which
includes the whole library, to allow adding Rubber Band Library to
a C++ project without having to build anything separately. This
version always uses the built-in FFT and resampler and does not
support any extra configuration
* Update the stretch calculation logic for real-time mode, making it
more rigorous about avoiding timing drift when the pitch ratio
changes frequently
* Update the example LADSPA pitch shift plugin, adding a wet/dry mix
control to test (and take advantage of) the better timing
management in real-time mode
* Add a pitch/frequency-map file option to the command-line utility,
allowing time-varying pitch shifts to be pre-programmed
The API is unchanged and the library is still binary compatible back
to version 1.7.
We incremented the major version number, not because of any API
change, but because of a change to the timing of audio output for some
applications of real-time mode. While the library is code-compatible
with earlier releases, it is not "output-compatible" and may change
automation-driven mixes even when used with identical options. If you
are already using an earlier release in real-time mode, please test
v2.0.0 carefully before updating.
Note that there are no pure bug-fixes in v2.0.0: if you are happy with
v1.9.2, there is no pressing reason to update.
