zakim, take up agendum 1
17:06:18 [Zakim]
agendum 1. "Web Audio Conference Session" taken up [from mdjp]
17:06:42 [hongchan]
mdjp: Web Audio Conference at IRCAM
17:07:24 [hongchan]
mdjp: the idea of having more representation from working group.
17:08:06 [mdjp]
http://wac.ircam.fr/
17:08:37 [hongchan]
mdjp: cwilso, padenot and me will be there.
17:09:41 [hongchan]
mdjp: we're looking through many papers and they are great examples of user-based outlet.
17:10:07 [hongchan]
mdjp: it is beneficial for use to provide support for them as we can.
17:10:57 [mdjp]
zakim, take up agendum 2
17:10:57 [Zakim]
agendum 2. "Assign open issues which need WG decision to V1 or V.next" taken up [from mdjp]
17:11:10 [joe]
https://github.com/WebAudio/web-audio-api/milestones/Needs%20WG%20decision
17:12:51 [hongchan]
joe: shall we just walk through this and discuss?
17:13:07 [hongchan]
cwilso: https://github.com/WebAudio/web-audio-api/issues/373
17:14:10 [hongchan]
…: I don't want to replace the buffer source node we already have.
17:14:32 [hongchan]
…: we could add another node can be resued.
17:15:25 [hongchan]
joe: this should be v.next.
17:16:25 [hongchan]
joe: move on to next issue.
17:16:35 [hongchan]
https://github.com/WebAudio/web-audio-api/issues/371
17:18:11 [hongchan]
cwilso: this came up while domenic want to rebuild audio element on top of web audio api.
17:18:54 [hongchan]
cwilso: it is about expanding features of decodingAPI.
17:19:08 [hongchan]
cwilso: this should be v.next.
17:19:56 [hongchan]
joe: don't we need some blanket solution?
17:20:28 [hongchan]
cwilso, padenot: blanket solution is not appropriate.
17:21:30 [hongchan]
joe: next inter-app audio. https://github.com/WebAudio/web-audio-api/issues/358
17:21:51 [hongchan]
cwilso: defer decision - leave it as needs working group decision.
17:22:16 [hongchan]
joe: what are we waiting for?
17:22:38 [hongchan]
cwilso: we need some guidance from developers and users.
17:22:53 [hongchan]
https://github.com/WebAudio/web-audio-api/issues/344
17:23:02 [hongchan]
padenot: I like this proposal
17:23:14 [hongchan]
cwilso: ok
17:23:58 [hongchan]
cwilso: I need to rethrough comments but I think we're heading to the same goal.
17:24:55 [hongchan]
cwilso: you can say ready for editing
17:25:03 [hongchan]
https://github.com/WebAudio/web-audio-api/issues/337
17:25:24 [hongchan]
cwilso: this is the big one, should go to v2.
17:25:33 [hongchan]
https://github.com/WebAudio/web-audio-api/issues/335
17:25:58 [hongchan]
padenot: straight forward to spec and doesn't break a thing.
17:26:14 [hongchan]
cwilso: this is not possible with promise because it's repeating
17:26:57 [hongchan]
it will change the signature in an unfortunate way
17:27:25 [hongchan]
joe: we need to know what the signature is when the callback
17:27:52 [Domenic]
in general progress + promises should be something like `getPromise(onProgressCallback).then(onSuccess, onFailure)`
17:28:01 [Domenic]
but in this case... not good
17:28:14 [Domenic]
streams is a better solution IMO for granular decoding
17:29:09 [hongchan]
cwilso: I will follow up with domenic and alex to see what the right pattern for this
17:29:26 [hongchan]
joe: I'll leave the review tag on it.
17:30:26 [hongchan]
https://github.com/WebAudio/web-audio-api/issues/331
17:30:53 [hongchan]
joe: it looks like chris wants to push this
17:30:59 [hongchan]
rtoy: works for me
17:31:46 [hongchan]
cwilso: I don't think analyzer is good for the process requires precision.
17:31:52 [hongchan]
https://github.com/WebAudio/web-audio-api/issues/323
17:32:01 [hongchan]
padenot: it doesn't break anything.
17:32:08 [hongchan]
cwilso: you mean creating a new node
17:32:57 [hongchan]
cwilso: certainly there are some demands for this.
17:33:26 [hongchan]
cwilso: it is easy to implement but the problem is the stability of biquad filter
17:34:38 [hongchan]
rtoy: i'd be happy to ignore this stability issue. then it's on developer's hand.
17:34:46 [hongchan]
joe: what is the current proposal?
17:35:02 [hongchan]
padenot: exposed coef as audioparam
17:35:17 [hongchan]
rtoy: k-rate
17:35:27 [hongchan]
joe: i'll mark this as v.1
17:35:37 [hongchan]
https://github.com/WebAudio/web-audio-api/issues/302
17:35:58 [hongchan]
joe: this is actually more than the progress
17:36:32 [hongchan]
joe: changing the content of offline audio context as progress.
17:37:14 [hongchan]
joe: my point of view - chair hat off - so you don't have create nodes up front.
17:37:45 [hongchan]
cwilso: rendering the hour of audio to get one file is not great.
17:37:56 [hongchan]
joe: that's what I think too.
17:38:19 [hongchan]
padenot: yeah i might be doable
17:38:58 [hongchan]
cwilso: there's is an alignment issue too.
17:39:41 [hongchan]
cwilso: it is doable but this is going to be a fairly big undertaking.
17:40:18 [hongchan]
joe: the question we should ask is - without it how offline context would be useful.
17:40:31 [hongchan]
joe: as developer - offline context needs this to be useful
17:41:02 [hongchan]
padenot: I think we can try for v1..
17:41:06 [hongchan]
cwilso: yeah
17:41:26 [hongchan]
joe: ok let's try. I will put it in the v1 bracket and we'll see.
17:41:34 [hongchan]
https://github.com/WebAudio/web-audio-api/issues/301
17:42:59 [hongchan]
cwilso: resampling is done elsewhere not our problem.
17:43:08 [hongchan]
joe: this is v.next
17:43:18 [hongchan]
https://github.com/WebAudio/web-audio-api/issues/296
17:43:19 [cwilso]
s/is done elsewhere/might be done elsewhere
17:44:19 [hongchan]
cwilso: if you change the playback rate it is hard to calculate the position.
17:44:58 [hongchan]
cwilso: we don't have sample accurate hook - so users will be disappointed anyway.
17:45:59 [hongchan]
cwilso: it is very good for visual feedback, and also good for making complex changes to playback rate. will make many things easier. (i.e. DJ app)
17:46:50 [hongchan]
padenot: yeah I agree
17:49:13 [shepazu]
q+
17:49:31 [shepazu]
q-
17:49:31 [hongchan]
joe: this goes to v.1
17:49:54 [hongchan]
https://github.com/WebAudio/web-audio-api/issues/264
17:50:49 [hongchan]
cwilso: this is about utilizing multiple audio tracks in media elements.
17:52:09 [hongchan]
cwilso: adding a new node. not a breaking change. should be in v.1
17:52:40 [hongchan]
joe: we need to have a clear way of determining the 'first' track.
17:53:04 [hongchan]
https://github.com/WebAudio/web-audio-api/issues/261
17:53:20 [hongchan]
cwilso: this is too late.
17:53:26 [hongchan]
padenot: yes, next.
17:53:40 [hongchan]
https://github.com/WebAudio/web-audio-api/issues/255
17:55:17 [hongchan]
cwilso: I would say this is appendix for last call. Should keep it in v.1.
17:56:11 [hongchan]
cwilso: non-normative description of all nodes.
17:56:26 [hongchan]
joe: okay I put that it the proposal and we can revisit later.
17:56:34 [hongchan]
https://github.com/WebAudio/web-audio-api/issues/248
17:57:12 [hongchan]
padenot: this would be useful - will cause big change.
17:57:43 [hongchan]
cwilso: I want to do the heavy lifting in the native code rather than the javascript.
17:57:45 [hongchan]
cwilso
17:57:57 [hongchan]
cwilso: it should be in v.next
17:58:49 [cwilso]
