(Bugzilla 17420) about numberOfOutputs of RealtimeAnalyserNode

State:

CLOSED

Product:

Web Audio API

Raised by:

James Wei

Opened on:

2012-03-23

Description:

In the spec of Web Audio API, for RealtimeAnalyserNode, there is a note for output number:

numberOfOutputs : 1 Note: it has been suggested to have no outputs here - waiting for people's opinions

The idea behind it is that It will be good that some inspector Node like
RealtimeAnalyserNode can pull without connect to downstream node which
ultimately connect to an audio destination.


Currently we have to connect RealtimeAnalyserNode to a GainNode with gain
as 0 and then connect to destination to analyze the stream and avoid to
impact the audio playing.


Another potential solution is to add multiple destination support in Web
Audio API and add a mock destination for the inspector purpose and this
destination is synced with the real destination.
