review recent spec changes

padenot: looking through https://github.com/WebAudio/web-audio-api/issues?direction=desc&page=1&sort=comments&state=closed

recently closed issues -> https://github.com/WebAudio/web-audio-api/issues?direction=desc&page=1&sort=created&state=closed

padenot: 320 was a real spec change
... the spec used to talk about un-neutering
... that's not possible in web platform
... was actually a security issue, had to fix that
... small behavioral change
... 316 and 315 were about promises. no change, just a nicer, more modern style
... 306 wasn't spec'd, now done
... is about passing an arraybuffer to convolvernode which isn't 1,2, 4 channels
... 299 is a syntactic change
... 294 was done to make things more symmetrical

(ditto 293)

padenot: 291 allows calling stop multiple times
... if you call twice, the last one is applied
... and first one ignored
... 290 was abour cross-origin behavior
... now if you load cross-origin resource without the flag, webaudio will use silence
... 289 was a big change, but not behavioral - refactoring of markup to use respec

shepazu: asking about 292. don't remember

padenot: references to commercial products, not IPR issues on the spec

olivier: what's next on your plate?

padenot: we are all waiting for scriptprocessornode in workers
... it really should be the next big thing
... wanted to spec the dynamiccompressornode before I get busy
... the other one I had in mind was the biquadfilternode
... extracting from the cookbook, use mathml to spec it

olivier: I thought we were going to refer to cookbook, not quote it

shepazu: I had that on my plate
