16:09:37 <mdjp> zakim, take up agendum 3
16:09:37 <Zakim> agendum 3. "Channel count of scheduled source nodes is unspecified when not playing? #462" taken up [from mdjp]
16:09:55 <Zakim> +[IPcaller]
16:10:16 <mdjp> https://github.com/WebAudio/web-audio-api/issues/462
16:14:22 <hongchan> cwilso: I don't think this is observable any more since we've fixed the channel merger node.
16:14:58 <ChrisL> ChrisL has joined #audio
16:15:47 <mdjp> zakim, take up agendum 4
16:15:47 <Zakim> agendum 4. "Easy way to get single most recent sample #493" taken up [from mdjp]
16:15:50 <Zakim> +ChrisL

16:16:16 <colinbdclark> colinbdclark has joined #audio
16:17:10 <hongchan> joe: I don't see why this can't be solved with AudioWorker.
16:17:25 <mdjp> zakim, take up agendum 5
16:17:25 <Zakim> agendum 5. "Review and classification of issues with no milestone" taken up [from mdjp]
16:17:44 <ChrisL> there was no clearly articulated use case for "most recent sample"
16:17:52 <mdjp> https://github.com/WebAudio/web-audio-api/issues?q=is%3Aopen+is%3Aissue+no%3Amilestone
16:19:05 <hongchan> Sorry - our room is sabotaging the meeting.
16:19:42 <mdjp> https://github.com/WebAudio/web-audio-api/issues/386
16:22:02 <hongchan> cwilso: this might be useful for some particular cases, like ultrasonics.
16:22:15 <hongchan> joe: if this is just implementation detail, we should just do it.
16:22:50 <hongchan> rtoy: Chrome does 2048 FFT always.
16:24:25 <hongchan> cwilso: morphing waveform might be bad in terms of the performance if we increase the limit.
16:24:52 <hongchan> rtoy: let me look at the implementation detail.
16:25:03 <ChrisL> answer to #509 is that they should all be a-rate? because they are often modulated at audio rate. And v1 clearly.
16:25:10 <mdjp> https://github.com/WebAudio/web-audio-api/issues/391
16:26:50 <ChrisL> repeated clamping accumulates error at each step, surely
16:26:59 <hongchan> cwilso: I still think this is a bad idea.
16:27:08 <ChrisL> zakim, unmute me
16:27:08 <Zakim> ChrisL should no longer be muted
16:28:00 <hongchan> ChrisL: repeated clamping accumulates error.
16:29:09 <hongchan> cwilso: this limits the other common use case of gain node.
16:31:15 <hongchan> BillHofmann: my concern is the different clamping behavior on the different audioparams.
16:32:02 <hongchan> mdjp: we should revisit this issue later after further consideration.
16:32:19 <mdjp> https://github.com/WebAudio/web-audio-api/issues/416
16:32:46 <hongchan> ChrisL: yes, dBFS makes more sense.
16:33:43 <mdjp> https://github.com/WebAudio/web-audio-api/issues/417
16:33:55 <ChrisL> Agree that Q should not be used (set to 1) there
16:34:28 <mdjp> https://github.com/WebAudio/web-audio-api/issues/418
16:35:11 <mdjp> https://github.com/WebAudio/web-audio-api/issues/419
16:36:55 <hongchan> ChrisL: we don't need to discuss this any more since this is solved by 418.
16:37:21 <ChrisL> detune should not be limited to 1200cents, certainly
16:37:21 <hongchan> rtoy: but this issue is related to other parameters than Q.
16:38:58 <hongchan> mdjp: this issue needs more thought.
16:40:13 <hongchan> rtoy: the cookbook formula was not what the implementation does, so I proposed to do what the implementation actually does.
16:40:31 <mdjp> https://github.com/WebAudio/web-audio-api/issues/436
16:42:24 <ChrisL> zakim, mute me
16:42:24 <Zakim> ChrisL should now be muted
16:43:40 <mdjp> https://github.com/WebAudio/web-audio-api/issues/441
16:44:28 <hongchan> rtoy: yes, InvalidAccessError is fine.
16:44:37 <mdjp> https://github.com/WebAudio/web-audio-api/issues/442
16:46:49 <hongchan> cwilso: I think it should be stayed in the spec, despite the fact that this should be observable.
16:46:52 <jernoble> jernoble has joined #audio
16:48:12 <hongchan> joe: yes, I think this is useful for developers to understand the lifetime and the observable-but-deferenced nodes.

16:53:29 <mdjp> https://github.com/WebAudio/web-audio-api/issues/447
16:55:14 <hongchan> mdjp: testing framework for potential v1 candidate.
16:55:43 <hongchan> mdjp: should revisit the independent testing framework by ChrisL.
16:55:49 <ghaudiobot> [web-audio-api] cwilso opened pull request #511: New factory-based AudioWorkers, with examples. (gh-pages...gh-pages) https://github.com/WebAudio/web-audio-api/pull/511
16:56:18 <mdjp> https://github.com/WebAudio/web-audio-api/issues/448
16:57:18 <mdjp> https://github.com/WebAudio/web-audio-api/issues/452
16:58:30 <hongchan> cwilso: MSADN is effectively a reference. yes.
16:59:31 <hongchan> cwilso: the real point here it should be observable is as long as they are connected to the destination node.
16:59:45 <hongchan> mdjp: we should come back to this one.
17:00:02 <ChrisL> my regrets for 30th (conference)
