Migrating projects using WebAudio’s PannerNode to Resonance Audio

Developer advantages

In addition to several general developer advantages, migrating to Resonance Audio has specific benefits for web developers.

Resonance Audio was designed to support Ambisonics and to scale well with a large number of sound sources, making your web application’s audio scalable and VR-ready. Resonance Audio also offers you direct access to Ambisonic channels.

Resonance Audio provides the following performance benefits over PannerNode:

How to migrate from PannerNode to Resonance Audio

To simplify the migration from WebAudio projects, the Resonance Audio Web SDK was designed with an API similar to WebAudio’s Panner Node.

For example, here is the same configuration in PannerNode and Resonance Audio:


// Create a PannerNode Panner object.
let panner = audioContext.createPanner();

// Initialize the panner properties.
panner.panningModel = 'HRTF';

// Connect an input to the panner.

// Connect the panner to audio output.

// Set the panner and listener positions.
panner.setPosition(x, y, z);
audioContext.listener.setPosition(x, y, z);

Resonance Audio

// Create a Resonance Audio Source object with properties.
let source = resonanceAudio.createSource({

// Connect an input to the source.

// Connect Resonance Audio’s output to audio output.

// Set the source and listener positions.
source.setPosition(x, y, z);
resonanceAudio.setListenerPosition(x, y, z);

To start migrating to Resonance Audio, see the Getting Started with Resonance Audio instructions for installing and including the Resonance Audio SDK in your projects.

Extending the Resonance Audio SDK for Web

Developers are encouraged to extend Resonance Audio and to contribute to the open source Resonance Audio SDK for Web project. See the on the Resonance Audio GitHub repo for more information.

Managing your Resonance Audio SDK software package

The Resonance Audio SDK uses webpack to build the minified library and to manage dependencies.

You can use the following npm commands to manage your software package.

  npm install         # install dependencies.
  npm run build       # build a non-minified library.
  npm run watch       # recompile whenever any source file changes.
  npm run build-all   # build a minified library and copy static resources.
  npm test            # launch the test runner
  npm run eslint      # lint code for ES6 compatibility.
  npm run build-doc   # generate documentation.
