olivier: want to better tag and prioritise issues
* Architectural / Fundamental - may result in breaking changes
* Non-testable assertions
* Clarification - requires (breaking?) changes to algorithms
* Clarification/Documentation/Editorial - no change to algorithms, results in documentation + tests
* Discrepancies in implementations - must results in test case, possibly results in clarification
* Missing Feature / Feature Request
* Syntactic improvements?
olivier: thoughts? anything missing, does it look useful?
shepazu: a lot of spec assumes
knowledge (of audio processing) or referencing something
outside
... e.g openAL, and the cookbook
... if there are others, maybe worth adding
olivier: agree - maybe we need something about references/dependencies
olivier: we now have value at t0 and phase, isnt that enough?
padenot: latest text has info
about phase
... 2.22.3 defines phase
olivier: will close issue as addressed in latest draft, can be reopened if anyone objects
olivier: new discussion on GH
about adding first order filters
... sounds like a new feature request, not quite clear in terms
of use case
padenot: met the OP, asked to
make a concrete list of use cases
... should be no problem
olivier: good - we'll prioritise when we have the UC
padenot: we have a proposed
solution for this
... we can work around it
... it's going to be delayed, but you can keep track of how
many loops played, and plan a stop in advance too
... and do it quite precisely
joe: a little bit uncomfortable
with adding events for predictable
... maybe what is needed is the ability to schedule an
arbitrary event at a certain audiocontext time
... if we had mapping between dom time and audiocontext
time
olivier: do we have an issue for that mapping?
joe: will check when I review bugs
<scribe> ACTION: joe to make sure we have an issue tracked for the mapping of dom time and audiocontext time [recorded in http://www.w3.org/2014/06/05-audio-minutes.html#action01]
<trackbot> Created ACTION-102 - Make sure we have an issue tracked for the mapping of dom time and audiocontext time [on Joe Berkovitz - due 2014-06-12].
issue 267 closed as WONTFIX
jernoble: talked to developer.
main topic was memory pressure
... one request was a way to queue multiple buffers
together
... append/concatenate buffers together
... something MSE does
... but not in web audio api
padenot: workers with scriptprocessornode could do it
jernoble: don't think we'd need
to do it with scriptprocessornode
... maybe change way decodeaudiodata works
... we could probably use a hack mixing audio element and
MSE
... but best to do in api
joe: last time this was discussed
was how to antialias the splicing
... not sure what the solution is, but this came up before
jernoble: there are restrictions
of MSE
... e.g if sources are too different
... we could do the same
joe: if we're not going to solve
splicing problem, why should we not tell people to do
sample-accurate scheduling
... issue with scheduling at sub-sample
jer: I thought we did have
sub-sample frame accurate scheduling in webkit, but haven't
checked in a while
... probably should add it if not
joe: if that's the way webaudio
works, we should spec it properly
... resolution of scheduling should be specced whether we need
this feature or not
<scribe> ACTION: joe to add/point to issue on sub-sample accurate scheduling [recorded in http://www.w3.org/2014/06/05-audio-minutes.html#action02]
<trackbot> Created ACTION-103 - Add/point to issue on sub-sample accurate scheduling [on Joe Berkovitz - due 2014-06-12].
olivier: would it make sense to hook into MSE?
jer: MSE currently doesn't expose the raw data
jernoble: but we can adopt some of the concepts of MSE
joe: question on issue that came
up in the past
... there is an issue that says spec is wrong about
playbackrate
[scribe missed details about detune]
olivier: joe, send mail to the list?
olivier: scheduled 19th june. any regrets
shepazu: couple of candidates for
co-chairing
... both known to the group, solid
... if both go through we will work on a smooth
transition
... we'll all be glad to be rid of olivier
[applause]
