padenot: reviewing code in gecko
and webkit, they seem different
... different math, but result is the same
... should be fine
(reviewed during last call- http://www.w3.org/2014/08/07-audio-minutes.html#item01)
padenot: will implement
CfC issued = http://lists.w3.org/Archives/Public/public-audio/2014JulSep/0061.html
olivier: have not seen objection to the breaking changes
<padenot> http://lists.w3.org/Archives/Public/public-audio/2014JulSep/0063.html ?
cwilso: not sure if ROC's comment was an objection
<padenot> ahh
cwilso: empathetic to the fact it
would be a breaking change
... will be tough but given IE is implementing at the moment,
we should take the heat
... harder to change if another browser implements it
joe: possible to make it clear that it is not part of the spec but keep it in implementations
cwilso: problem is we can't have
things that are not in the spec but necessary for code that is
in web at large
... cwilso explains impact on interop
+1
padenot: possible to offer a monkey patch for people to transition
cwilso: was thinking through this
this AM
... should be possible
... not going to be a trivial monkeypatch
... challenge is to do the post messaging back and forth; hope
for the best
... padenot: it's already broken, so...
... might take a browser engineer to write the polyfill, give
it to all
cwilso: will write blog post
padenot: should start logging
into browser console
... with link to blog post
olivier: wondering about scheduling of publication, blog post etc
cwilso: we need to have the
ability to polyfill old version on top of the new
... think we should publish draft and polyfill ASAP
... and wait before removing the old one
olivier: can it be marked as deprecated for now
cwilso: sure
olivier: wondering if we could get help from W3C comms... maybe w3c homepage item
<scribe> ACTION: olivier to reach out to W3C comms, ask for help re deprecation of spn [recorded in http://www.w3.org/2014/08/28-audio-minutes.html#action01]
<trackbot> Created ACTION-110 - Reach out to w3c comms, ask for help re deprecation of spn [on Olivier Thereaux - due 2014-09-04].
olivier: we haven't published anything on /TR for a while
[discussing changelog]
olivier: don't think we have
published since the data races fix
... sounds like we should publish soon
cwilso: would prefer to get AudioWorker stuff in before
RESOLUTION: publish webaudioapi to /TR after Audioworker changes included
olivier: what about web midi
[noticing link to editor's draft in webmidi is broken]
olivier: what about (first) last call for webmidi?
cwilso: still have open issues,
would prefer to go through them and see what needs to be
fixed
... may not stand in the way of a last call
olivier: suggest we review state of webmidi after we publish webaudioapi to TR, with AudioWorker stuff included
RESOLUTION: review webmidi issues after publication of webaudio, decide on Last call then
http://cwilso.github.io/web-audio-api/pr_ignore.html#widl-AudioContext-release-Promise
https://github.com/WebAudio/web-audio-api/issues/317
olivier: wondering about
release...
... is that unusual?
padenot: whatwg spec mention explicitely the UA should release when the src attribute is removed
cwilso: no control over when GC
is happening
... problematic for something like audiocontext which takes
limited resources
padenot: we have similar issue with FFOS
<scribe> ACTION: cwilso to ping TAG about novel(?) method to impact GC [recorded in http://www.w3.org/2014/08/28-audio-minutes.html#action02]
<trackbot> Created ACTION-111 - Ping tag about novel(?) method to impact gc [on Chris Wilson - due 2014-09-04].
https://github.com/WebAudio/web-audio-api/issues/348
[looking at comment thread]
jer?
jer: still unsure, need more
thinking
... would prefer wrapping into something a little higher
level
... we have this concept in iOS
cwilso: agree there may be other
features we may want to wrap together
... this is beneath that - about implementation
... driven by request from google play
... don't want to rip control of that from the UA
jer: does this have client-side visible effect?
cwilso: only discernable impact
is in pattern of power consumption
... and difference in timing if you have a # of SPN
jer: what if we have latency reporting
cwilso: yes, we would see it
jer: then would have to be careful, if there may be visible effect
cwilso: we have this today
already
... we get different latency numbers
jer: fine with giving control to script, but will be difficult to get api right
cwilso: happy to discuss different APIs
cwilso: three things I wanted to
bring up
... request to change audiobuffer to float32
... ok with that
... but we should separate event/have different name
... any objection?
<cwilso> https://www.irccloud.com/pastebin/F9BgLmgV
http://lists.w3.org/Archives/Public/public-audio/2014JulSep/0139.html ?
joe: if we change event name,
would probably make it OK
... cwilso made the same point
olivier: sounds like consensus
cwilso: plan to make change to float32arrays, change name, mark old one as deprecated
olivier: make it so
<joe> must leave now; fractional regrets
jer: wanted to know status of web audio test suite
olivier: no recent progress but we need to pick up, want to deal with arch changes soon, then focus time at and after TPAC on testing
tentative date for next meeting: 11th Sept
ADJOURNED
padenot: tentative regrets for the 11th
olivier: fine, make sure to have moz rep if possible
