Notes
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?
