Description Marcus Geelnard (Opera) 2012-06-18 11:27:42 UTC 
The JavaScriptAudioNode does not have the ability to dynamically change its number of input/ouptut channels after creation.

This makes it impossible to re-implement nodes such as AudioGainNode (depends on number of input channels) and ConvolverNode (depends on number of AudioContext output channels - according to [1]).
