Writing team

Primary writer.

Other MDN contributors may of course participate as well!


Currently in progress

chrisdavidmills not currently working on anything, but will start DynamicsCompressorNode soon.

Tagging standard

  • Grouping tag is: "Web Audio API"

Other tasks to do

The currently-supported interfaces have all been documented! It would be great to have getting these tech reviewed though.

We also have the AudioWorkerNode/AudioWorkerGlobalScope/createAudioWorker stuff to do soon, when it is implemented. It was added to the spec as of 29/08/2014.

Tutorial to-do list

  • Manipulating audio params
  • Offline audio processing
  • Using script processor nodes

Notes for translators

Any notes here? Where do we expect updates, so that localizers don't translate and update too often?
