[slightly late] Version 1.3 of the Rubber Band library is now available. http://breakfastquay.com/rubberband/ 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. Version 1.3 is a maintenance release. It fixes a bug that may cause incorrect output during the first process block of some audio files, when processing in offline mode. It also fixes a small number of build issues and more minor bugs. The library is binary compatible with version 1.2. Chris
