SUMMARY="Audio processing library for changing tempo, pitch and playback rates"
DESCRIPTION="
* Easy-to-use implementation of time-stretch, pitch-shift and sample rate
transposing routines.
* High-performance object-oriented C++ implementation.
* Full source codes available for both the SoundTouch library and the example
application.
* Clear and easy-to-use programming interface via a single C++ class.
* Supported audio data format : 16Bit integer or 32bit floating point PCM
mono/stereo
* Capable of real-time audio stream processing:
    * input/output latency max. ~ 100 ms.
    * Processing 44.1kHz/16bit stereo sound in realtime requires a 133 Mhz
      Intel Pentium processor or better.
