Audio-ISSUE-14 (quinnirill): Default value for bufferSize in createJavaScriptNode() [Web Audio API]

http://www.w3.org/2011/audio/track/issues/14

Raised by: Jussi Kalliokoski
On product: Web Audio API

Jussi Kalliokoski suggested that the first argument of AudioContext:createJavasScriptNode, (buffer size) would be made optional.

In addition, it could be specified so that an advanced implementation would adjust the default value to be an optimal balance between reliability (avoiding glitches and underruns) and latency on that system and setup.

«
We discussed with Chris (off-list) the recent change from numberOfOutputs
to numberOfChannels in the createJavaScriptNode(), because I noticed my
sink.js was broken in the latest Chrome Canary.

I suggested that the first parameter (bufferSize) be optional as well,
reverting to default when passed undefined. In an advanced implementation,
this default could be adjusted to a value that the implementation deems a
good tradeoff between safety (avoiding underruns) and latency on that
system and setup. I believe Chris thinks this is a good idea, so he
suggested I bring this to discussion in the group so we can change the spec
if we agree on it.

The method is currently defined as:

ScriptProcessorNode createScriptProcessor(optional unsigned long bufferSize = 0 …

Is this issue still valid or is has it been fixed already?

Updating issue title to reflect the change of name from JavaScriptAudioNode to
ScriptProcessorNode, and in particular the createScriptProcessor method.

I think it's safe to call this fixed.
