Version 3.0.0 of Rubber Band Library is now available. https://breakfastquay.com/rubberband/ 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. This is an exciting major release which, among other things, introduces an entirely new processing engine known as the R3 or Finer engine. This typically produces substantially higher-quality output than the existing engine (now referred to as R2 or Faster), although at higher CPU cost. The more energy-efficient R2 is still the default, and R3 can be selected using the new OptionEngineFiner option on construction. I'm immensely proud of the work done for this release, and hope it will delight you and all the users of your software. Chris
