Bungee

Bungee Pro

First released in 2024, Bungee Pro is a technology for manipulating the speed of audio without changing pitch, or changing pitch without affecting speed. The product of extensive original research, Bungee Pro's unique processing delivers a high-quality audio output without the robotic, “phasey” and “distant” side effects generally associated with audio timescale processing.

  • Designed to work with all audio types: speech, vocals, monophonic and polyphonic music.
  • No compromises: expert-developed and AI-based algorithms work together to reproduce crisp transients, lush tones and authentic timbre.
  • Slick performance: Built for modern consumer devices and optimised for minimal energy and memory usage.

The Bungee Pro Native SDK comes with C++ headers and binary libraries for iOS, Mac, Windows, Linux and Android.

The Bungee Pro Web SDK combines the audiophile prowess of Bungee Pro with the ubiquity of web standards. It enables web apps to stretch, warp and change the pitch of audio from within any of the major browsers or webviews. The Web SDK powers our demo page.

Both Native and Web SDKs are available under straightforward license terms. If your project might benefit from the quality and performance of Bungee Pro, we'd love to hear about it.

Bungee Open Source

Bungee is maintained as an open-source project. It is a foundational library for audio time-stretching and pitch-shifting.

  • Basic phase vocoder implementation for good performance on all types of audio.
  • Seamlessly supports all time-stretching ratios, including zero and negative playback speeds.
  • Uses the same C++ API as Bungee Pro Native, facilitating future upgrades.

To start using Bungee, check out the repository.

The demo left our team and some external consultants thoroughly impressed. They mentioned they hadn’t heard anything better in this domain.

I guess this is by far the best open source stretcher
