Superpowered Web Audio JavaScript and WebAssembly SDK
Allows developers to implement low-latency interactive audio features into web sites and web apps with a friendly JavaScript API.
Superpowered Web Audio JavaScript and WebAssembly SDK is a cutting-edge WebAssembly-based library featuring low-power, real-time latency and cross-browser audio Fx, audio I/O, music analysis and spatialization.
DownloadNative Quality
No compromises: audio quality is identical to our "native" platform versions.
Native Performance
All data processing is performed in WebAssembly for high performance.
Time Stretching
Worlds first low-latency real-time audio time-stretching in any major web browser.
Easy API
Develop using a standard JavaScript API. Front-end developers can design high performance audio apps now. Use vanilla JS or any of your favorite frameworks.
Web Audio
Seamlessly integrates with Web Audio, supporting both the old ScriptProcessorNode and the new Audio Worklet.
Every Major Browser
Works with the offical stable versions of every major web browser. MS Edge requires version 74.
Superpowered Interactive Audio Features
Write once, run anywhere
Launching interactive audio apps on multiple web browsers and multiple devices requires powerful DSP that provides unified performance with recuding complexity. Dealing with web browser performance idiosyncrasies is frustrating and non-productive.

What They're Saying
Spotify
Superpowered is in a category entirely of its own. I love working with them on hard-to-solve audio tech problems.
Voloco
Superpowered's high-performance DSP APIs allowed us to write our audio engine once and run it successfully on everything from the latest iPads to lower-end Android devices. Without it, we wouldn't be doing real-time, eight-voice vocal harmonies on cheap phones.
Microsoft
Superpowered audio is advanced cross-platform audio processing technology, wrapped in an easy to use API. Superpowered does all the low-level, heavy lifting that would otherwise take multiple vendors running multiple technologies to even come close.
