soundtouch

SoundTouch is a C++ audio processing library that allows
changing the sound tempo, pitch and playback rate parameters
independently from each other.

Implements time stretch, pitch shift and sample rate transposing
routines.
Supports the 16-bit integer or 32-bit floating point
PCM mono/stereo formats.
Capable of real-time audio stream processing (depending on hardware).
Additional use of assembler level and Intel MMX instruction sets.
