About:
SoundTouch is an open-source audio processing library for changing the tempo, pitch, and playback rate of audio streams. It provides a robust API for real-time processing and offline rendering, making it ideal for applications requiring audio time-scale modification. The library is optimized for high performance and low latency across multiple platforms.

Key Features:

Time-stretching (tempo change without pitch alteration)
Pitch-shifting (change pitch without affecting tempo)
Sample rate conversion
Real-time processing capabilities
Cross-platform support (Windows, Linux, macOS)

Use Cases:

Audio player applications for variable speed playback
Podcast editing software for time compression
Karaoke applications for pitch adjustment
Game audio engines for dynamic audio manipulation

Alternatives:

libsamplerate – Focuses specifically on sample rate conversion rather than comprehensive time-stretching and pitch-shifting
Rubber Band Library – Similar functionality with different algorithmic approaches and licensing terms
