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
