(Bugzilla 17424) Setting sample rates for individual JavaScriptProcessingNodes

State:
CLOSED
Product:
Web Audio API
Raised by:
Jussi Kalliokoski
Opened on:
2012-03-05
Description:
Ideally, the end developer should be able to create custom processing nodes with specific sample rates within a single AudioContext. This is very useful, since high quality resampling in JavaScript is relatively expensive, and a required feature for anything that deals with external media sources, for example JS codecs.

The sample rate should also be possible to be changed on the fly to allow for features like changing the playback rate of a codec (required if you'd want to use JS codecs to extend <audio> for example).

Resolution: add a constructor parameter for audio context to specify sample rate - make sure to specify that default is best unless needed.
