Version 1.9.2 of the 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.
Version 1.9.2 is a maintenance release. The main change is the addition of a built-in double-precision FFT of efficiency similar to KissFFT, which can be used when there is no pressing reason to prefer an external library. This is the default option on non-Apple platforms (on which vDSP remains the default), simplifying configuration, although FFTW and IPP are still supported where available. This release also includes a few configuration tweaks and fixes a possible memory error. See the CHANGELOG file for more details.
The library is binary compatible with versions 1.7, 1.8.x, and 1.9.
