Changed in Rubber Band v1.5
Changes in Rubber Band v1.6
* Add Smoothing option. This uses a window-presum FFT, introducing
time-domain aliasing which is then smoothed using a sinc window.
This can be used in combination with any of the existing processing
control options. This will soften transients but the result may
still be more pleasant for some material that is not very amenable
to being time stretched.
* Fix silent channel of output when processing with band-limited
transients option
* Include libresample support
The library is binary compatible with version 1.5 for forward
compatibility (values have been added to an existing enum). Code
written to use 1.6 is not necessarily compatible with 1.5.
