Rubber Band Library version 2.0.0 released
------------------------------------------

Version 2.0.0 of [[/rubberband|Rubber Band Library]] is now
available.

Rubber Band Library is an audio time-stretching and pitch-shifting
library and utility designed for musical applications. It allows you
to change the tempo and pitch of an audio recording independently of
one another.

* Easier integration

This release is designed to be easier than ever to integrate into a
project. It introduces a single-compilation-unit build mode that can
be added to a C++ project build without any additional dependencies.

In support of this, Rubber Band Library now has a built-in resampler
(as an alternative to the external options that were already
supported) which, in tandem with the built-in FFT introduced in
version 1.9.2, allows the library to be built with no external library
dependencies other than the C++ standard library.

* Stricter real-time timing precision

This release also introduces improved timing calculation logic when
running in real-time mode, for more stable timing when the pitch shift
is changing dynamically. The new resampler is also designed to
minimise audible artifacts when changing pitch, giving better results
all round when used with frequent dynamic adjustments.

* Still backward-compatible

The Rubber Band Library API is unchanged and the library is still
binary compatible with versions 1.7, 1.8.x, and 1.9.x.

We incremented the major version number to 2, not because of any API
change, but because our timing precision work has changed the 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.

Existing commercial licences remain valid for v2.0.0.

Happy stretching!
