Bungee

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 an adaptive phase vocoder for reliable performance across all audio types.
• Supports all time-stretching ratios, including reverse (negative) and zero-speed playback.
• Uses 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.

• No compromises on audio quality: expert-developed and AI-enhanced algorithms preserve crisp transients, lush tones, and authentic timbre.
• Works well with all audio types: speech, vocals, monophonic and polyphonic music.
• Optimized for realtime usage on consumer devices with very low CPU 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 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.
