Bungee (Open Source)
Bungee is an open-source audio processing library designed to change playback speed without affecting pitch—or adjust pitch without altering speed.
- Implements a basic phase vocoder for reliable performance across all audio types.
- Supports all time-stretching ratios, including reverse (negative) and zero-speed playback.
- Shares the same C++ API as Bungee Pro, enabling a seamless upgrade path.

Bungee Pro
Built on the foundation of open-source Bungee, Bungee Pro is a proprietary, professional-grade audio processing technology. It delivers industry-leading audio quality—without the robotic, phasey, or distant artifacts common in conventional timescale modification tools.
- Compatible with all audio types: speech, vocals, monophonic and polyphonic music.
- No compromises: expert-developed and AI-enhanced algorithms preserve crisp transients, lush tones, and authentic timbre.
- Optimized for modern consumer devices with efficient energy and memory usage.
The Bungee Pro Native SDK includes C++ headers together with binary libraries for iOS, macOS, Windows, Linux, and Android.
The Bungee Pro Web SDK brings Bungee Pro’s high-fidelity audio processing to the web. It enables web applications to stretch, warp, and pitch-shift audio directly in all major browsers and webviews. The Web SDK also powers our interactive demo.
Both SDKs are available under simple, developer-friendly licensing terms. If your project could benefit from Bungee Pro’s performance and audio quality then we’d love to hear from you.
