Version 1.5.0 of the Rubber Band Library is now available.
Rubber Band 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.
This release adds a key-frame mapping facility, for managing variable stretch ratios within a single offline time-stretch pass. It also includes a more reliable transient detection mode for soft instruments and band-limits the transient detectors to improve performance with compressed or lower-quality material.
The library is binary compatible with version 1.4 for forward compatibility. Code written to use 1.5.0 is not necessarily compatible with 1.4, as one new function and one enum have been added.
