17:03:50 <cwilso> zakim, pick a victim
17:03:51 <Zakim> Not knowing who is chairing or who scribed recently, I propose cwilso
17:04:13 <cwilso> scribenick: cwilso
17:04:34 <cwilso> zakim, take up agendum
17:04:34 <Zakim> I don't understand 'take up agendum', cwilso
17:04:40 <cwilso> zakim, agendum 1
17:04:40 <Zakim> I don't understand 'agendum 1', cwilso
17:05:11 <mdjp> zakim, take up agendum 1
17:05:11 <Zakim> agendum 1. "Proposal for separate multiple-I/O AudioWorker API and single-I/O AudioWorker API (action from previous meeting)" taken up [from mdjp]
17:05:36 <ChrisL> ChrisL has joined #audio
17:06:00 <cwilso> mdjp: cwilso, has this been done?
17:06:19 <cwilso> cwilso: the former (multi-io) has been proposed, the latter (factory model) has not.
17:06:32 <Zakim> +ChrisL
17:06:51 <joe>  http://cwilso.github.io/web-audio-api/

17:10:19 <Zakim> +[IPcaller]
17:10:30 <padenot> Zakim, IPcaller is me
17:10:30 <Zakim> +padenot; got it
17:11:12 <cwilso> cwilso: talks through the proposal's createAudioWorker
17:11:48 <cwilso> http://cwilso.github.io/web-audio-api/#h3_the-audioworker
17:12:18 <Zakim> +Doug_Schepers
17:13:10 <cwilso> http://cwilso.github.io/web-audio-api/#idl-def-AudioProcessEvent
17:14:07 <cwilso> bitcrusher example:
17:14:11 <cwilso>     var inputBuffer = e.inputs[0][channel];
17:14:11 <cwilso>     var outputBuffer = e.outputs[0][channel];
17:15:15 <cwilso> cwilso: it's unfortunate that the 99% case gets harder due to the 1% scenario
17:18:28 <cwilso> joe: points out that input channels shouldn't be dynamically changeable
17:21:40 <cwilso> mdjp: we should post to the list asking for more review of this and put it on the next agenda
17:22:06 <cwilso> joe: I think the current proposal seems fine (and we probably shouldn't multiply the number of ways to do similar things)
17:23:45 <shepazu> agenda+ github issues on mailing list
17:24:41 <mdjp> zakim, take up agendum 2
17:24:41 <Zakim> agendum 2. "Audio Worker "bypass" Attribute #456 (In the "needs WG Decision" queue)" taken up [from mdjp]
17:24:59 <cwilso> mdjp: should we put factory model on for next time?
17:25:06 <cwilso> cwilso: sure, although I may not have it done.  :)
17:25:09 <mdjp> https://github.com/WebAudio/web-audio-api/issues/456
17:26:55 <cwilso> cwilso: I think we should punt for v1
17:27:02 <cwilso> paul: +1
17:27:05 <cwilso> joe: +1
17:28:02 <mdjp> zakim, take up agendum 3
17:28:05 <padenot> mdjp: I can't really get anything you're saying from here
17:28:18 <cwilso> zakim, agenda?
17:28:18 <Zakim> I see 5 items remaining on the agenda:
17:28:18 <mdjp> zakim, take up agendum 3
17:28:20 <Zakim> 1. Proposal for separate multiple-I/O AudioWorker API and single-I/O AudioWorker API (action from previous meeting) [from mdjp]
17:28:20 <Zakim> 2. Audio Worker "bypass" Attribute #456 (In the "needs WG Decision" queue) [from mdjp]
17:28:20 <Zakim> 3. Inter-app audio (Consistent request from ISVs, a la VSTs, Audio Units, Rack Effects) #358 (In the "needs WG Decision" queue) [from mdjp]
17:28:20 <Zakim> 4. AOB [from mdjp]
17:28:21 <Zakim> 5. github issues on mailing list [from shepazu]
17:28:23 <Zakim> agendum 3. "Inter-app audio (Consistent request from ISVs, a la VSTs, Audio Units, Rack Effects) #358 (In the "needs WG Decision" queue)" taken up [from mdjp]
17:28:45 <joe> mdjp: can't understand you. try muting while you speak
17:29:04 <joe> never mind
17:29:07 <joe> stupid idea
17:30:08 <mdjp> https://github.com/WebAudio/web-audio-api/issues/358
17:30:22 <Zakim> -mdjp
17:31:14 <Zakim> +??P3
17:31:28 <mdjp> Zakim, ??P3 is me
17:31:28 <Zakim> +mdjp; got it
17:35:38 <Zakim> -ChrisL
17:36:37 <Zakim> +ChrisL
17:37:04 <cwilso> cwilso: I think we should keep this moving along.
17:37:12 <cwilso> jerry: is this still a v1 topic?
17:38:23 <joe> q+
17:38:45 <mdjp> ack joe
17:40:02 <cwilso> cwilso: I think "v1" is just a name.  I think we need to examine the underlying architecture of audio, and how bits move around in the system.  I think interapp audio is in the same bucket as access to different inputs/outputs and direct stream access
17:40:24 <ChrisL> I agree, interap audio is important and hard and could be deferred from v1
17:40:30 <cwilso> joe: to me interapp audio comes later than defining the processing system.  IAA shouldn't gate the viability of this api.
17:41:19 <cwilso> joe:  we could just get rid of numeric milestones, although I'm not necessarily recommending that
17:42:00 <cwilso> mdjp: I agree with that; this doesn't really fit into the v1/vnext taxonomy; we need some action to resolve it either way, though.
17:42:20 <shepazu> q+
17:42:27 <mdjp> ack shepazu
17:42:49 <cwilso> q+
17:43:10 <mdjp> ack cwilso
17:43:13 <cwilso> shepazu: even if this isn't in the first Rec spec, we still want to make sure we have the architectural pieces to accomodate it later
17:44:30 <joe> q+
17:44:34 <cwilso> https://github.com/WebAudio/web-audio-api/issues/445
17:45:10 <mdjp> ack joe
17:45:20 <cwilso> cwilso: I think this is kind of blocked behind the input and output stream magic
17:45:54 <cwilso> joe: do you mean we need to abstract sources/destinations outside of the WA api?
17:48:26 <cwilso> cwilso: yes: we need to crack open how source/destinations work.
17:48:42 <ChrisL> our use cases are not their use cases, basically
17:49:09 <cwilso> joe: we seem to get hung up in the RTC realm on the enumerations.  Can we make progress on the abstractions anyway?
17:49:14 <shepazu> q+
17:49:17 <cwilso> q+
17:49:21 <mdjp> ack shepazu
17:49:23 <ChrisL> q+
17:50:31 <cwilso> shepazu: the goal of the platform is to be well-integrated, which is why we encourage cross-WG coordination.  We *can* put forward ideas in the RTC space.
17:51:11 <cwilso> shepazu: we should come up with what we want to see from the RTC group and talk through it with them.
17:51:37 <mdjp> ack cwilso
17:55:38 <mdjp> ack ChrisL
17:57:05 <cwilso> cwilso: we need bare metal APIs for audio API.  I think it's this group's responsibility to make sure those are happening.  Some bits are being defined in RTC - which is fine, and they're doing a reasonable job - but driving that "audio streaming" api is not their milieu, today.
17:57:33 <cwilso> chrisl: pinning down requirements here is likely critical.
17:57:58 <shepazu> q+
17:58:06 <mdjp> ack shepazu
17:58:16 <cwilso> cwilso: the audio wg likely has two levels we need to work on: the current processing API, and bare metal access to audio i/o and device enumeration.
17:58:32 <cwilso> shepazu: chairs should schedule time for us to talk about use cases / scenarios.
17:59:07 <cwilso> cwilso:  we have use cases - we should probably look at them again.
17:59:18 <cwilso> joe: yeah, I wrote a lot of them - I should probably take a look again.
17:59:46 <shepazu> agenda?
