Rubber Band is an audio time-stretching and pitch-shifting library and utility designed for musical applications. http://www.breakfastquay.com/rubberband/ It includes a library that supports a sample-accurate multithreaded offline mode and a real-time lock-free streaming mode; a command-line utility program; and a LADSPA pitch-shifter plugin. Rubber Band is Free Software under the GNU GPL. This small update (v1.0.1) fixes an option parsing bug and a dodgy bit of #ifdef nesting. The core code is the same as in 1.0. Chris
