<cwilso_> scribenick: hongchan

joe: who's going to f2f meeting this year?

<shepazu> shepazu is going

cwilso: I am going too, but will be able to attend part of TPAC, because of the US holiday Halloween
... has any one reviewed joe's proposal?
... native nodes are immediately accessible thanks to factory pattern.
... joe's current proposal describes only factory style worker.

joe: our two proposals have become very close - the difference is 1) to be able to wait for the factory to load script (factory to fire 'onload' event')

cwilso: if there is no node configuration in the external script, you don't have to wait for onload event

joe: the point is to give developers 'onload' event to work with.

cwilso: I didn't mean that you should not have 'onload' event.

joe: two models of worker script?

cwilso: 1) factory 2) non-factory
... what happen you create a node and change a parameter inside?

joe: we can keep going on this item.

cwilso: we should let people review them first.

padenot: developers wants to have a callback when the node is initialized.

joe: opinion on layering?

padenote: we're just pretending that they're happening synchronously when it's not.

cwilso: sounds interesting and it's something can be prototyped with AudioWorker, not for V1.

<rtoyg_m> hongchan: Presents proposal.

<rtoyg_m> hongchan: Inputs that are not connected produce one channel of silence to the output.

<rtoyg_m> https://github.com/WebAudio/web-audio-api/issues/459

<rtoyg_m> hongchang: Spec is unclear on how merger node works in a cycle.

AOB

padenot: should throw IndexSizeError

hongchan: that makes sense for input/output indices.

padnote: InvalidState?

hongchan: raymond and I think 'invalidstate' makes sense here.

padenot: yes, it might work - let's go for that.

<joe> https://github.com/WebAudio/web-audio-api/issues/469

<rtoyg_m> https://github.com/WebAudio/web-audio-api/issues/469

<rtoyg_m> Also https://github.com/WebAudio/web-audio-api/issues/322

padenot: some nodes introduce some internal latency.

<rtoyg_m> Issue 322 (waveshaper) is a good example.

padenot: this latency info might be useful to compensate it on multiple audio paths.

rtoyg_m: I will update the bug later.
