19:06:38 <olivier> zakim, take up agendum 1
19:06:38 <Zakim> agendum 1. "Review of web audio API ED changes" taken up [from olivier]
19:06:52 <olivier> Agenda: http://lists.w3.org/Archives/Public/public-audio/2012AprJun/0069.html
19:07:07 <olivier> http://lists.w3.org/Archives/Public/public-audio/2012AprJun/0068.html
19:07:55 <jernoble> olivier: call for comments and questions about recent changes to the WebAudio API
19:08:24 <jernoble> (no comments or questions)
19:08:27 <olivier> zakim, take up next agendum
19:08:27 <Zakim> agendum 2. "Channel handling (ISSUE-9)" taken up [from olivier]
19:08:34 <olivier> ISSUE-9?
19:08:34 <trackbot> ISSUE-9 -- Multi-Channel support in Use Cases & Reqs. -- open
19:08:34 <trackbot> http://www.w3.org/2011/audio/track/issues/9
19:10:14 <jernoble> chris: an introduction to how multichannel audio is dealt with in the WebAudio API
19:10:39 <jernoble> … WebKit implementation assumes stereo output, irrespective of hardware channel support
19:11:37 <jernoble> … may need to add a new API in the AudioContext (either in the constructor or later) to query for hardware channel support
19:12:02 <cwilso> cwilso has joined #audio
19:12:23 <jernoble> olivier: issue surrounding javascript node and a single channel input and output; the WebKit implementation assumes stereo in and out
19:12:49 <jernoble> chris: not intentional.  results are due to a bug in webkit which may be recently fixed
19:13:11 <Zakim> +ChrisWilson
19:13:18 <jernoble> … number of output channels on a javascript node were previously ignored; now fixed
19:13:33 <jernoble> .. another bug where the number of input nodes is also being ignored; will also soon be fixed.
19:13:59 <jernoble> Topic: Use Cases and Deployment Document
19:14:19 <jernoble> olivier: document only mentions number of channels in one use case; specifically mixing multiple channels into one
19:14:57 <jernoble> … would there be value in adding to one of our use cases to a) handle >2 channels as output and b) ability to down mix to 2 channels regardless of hardware support for >2 channels.
19:15:18 <jernoble> chris: has no objection to adding those use cases.
19:15:56 <jernoble> olivier: use cases section of document is not normative (??) so adding prospective use cases is fine
19:16:05 <olivier> zakim, next agendum
19:16:05 <Zakim> agendum 3. "Gain negative or above 1 (ISSUE-10)" taken up [from olivier]
19:16:24 <olivier> ISSUE-10
19:16:28 <olivier> ISSUE-10?
19:16:28 <trackbot> ISSUE-10 -- Negative values suggested for the Audio Gain Node -- pending review
19:16:28 <trackbot> http://www.w3.org/2011/audio/track/issues/10
19:17:12 <jernoble> olivier: Issue was pretty much solved: talked about last week, and a spec change resulted. 
19:17:40 <jernoble> olivier: call for further comments or questions about the spec change.
19:17:48 <jernoble> (no comments or questions)
19:18:11 <olivier> RESOLVED: change to the API satisfying ISSUE-10, can close
19:18:33 <olivier> zakim, next agendum
19:18:33 <Zakim> agendum 4. "Offline audio context (ISSUE-11)" taken up [from olivier]
19:18:40 <olivier> ISSUE-11?
19:18:40 <trackbot> ISSUE-11 -- Offline Audio Context -- open
19:18:40 <trackbot> http://www.w3.org/2011/audio/track/issues/11
19:19:45 <jernoble> chris: this still needs to be added to the spec; will add it soon.
19:19:55 <jernoble> olivier: is there any controversy about this change?
19:20:16 <jernoble> chris: not really.  work is ongoing in the WebKit implementation.  will add to the spec in the next few days.
19:20:35 <jernoble> joe: this is an important feature for a number of use cases; would like to see it added to the spec.
19:20:50 <shepazu> agenda+ midi and charter
19:21:15 <jernoble> olivier: this has been documented in at least one of the use cases. agreed that it is important.
19:21:35 <olivier> zakim, next agendum
19:21:35 <Zakim> agendum 5. "midi and charter" taken up [from shepazu]
19:23:01 <jernoble> shepazu: propose that we add MIDI to the charter
19:23:19 <jernoble> olivier: seems to remember that cwilso already added this to the charter
19:23:55 <shepazu> http://lists.w3.org/Archives/Public/public-audio/2012JanMar/0290.html
19:24:07 <joe> Some user agents have connected music devices, such as synthesizers, keyboard controllers and drum machines.  The widely adopted MIDI protocol enables electronic musical instruments, controllers and computers to communicate and synchronize with each other. MIDI does not transmit audio signals: instead, it sends event messages about musical notes, controller signals for parameters such as volume, vibrato and panning, cues and clock signals to set the tempo, and sys
19:24:34 <jernoble> shepazu: will go forward with updating the charter.
19:24:46 <olivier> RESOLVED: charter will be updated with Chris Wilson's proposed wording from Feb 27th

19:28:50 <olivier> rrsagent, make logs public
19:28:55 <olivier> rrsagent, make minutes
19:28:55 <RRSAgent> I have made the request to generate http://www.w3.org/2012/04/25-audio-minutes.html olivier
19:28:59 <jernoble> Oh, and sorry about the ellipses; autocorrect trims them down to a single unicode character. (i.e. ...)
19:29:00 <olivier> zakim, bye
19:29:00 <Zakim> Zakim has left #audio
19:29:41 <olivier>  hopefully the perl script taking care of minutes does unicode right
