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?


The interfaces defined in the following specifications are tracked by this status page:
