<padenot> nope, I'm not muted locally

<padenot> it's just skype acting funny

<padenot> hm, apparently, the SIP gods don't want me to update you on this

<olivier> https://github.com/WebAudio/web-audio-api/pull/270

<cwilso_> Here is a proposal: padenot@ff13d62, or http://padenot.github.io/web-audio-api/#band-limiting.

olivier: I think that's what padenot mentioned the other day.

cwilso_: I think we need padenot here to have this conversation. Let's delay for now?

<padenot> yeah, sorry, I'm afraid something went wrong here

olivier: the definition of phase looks to be done (in PR 270), so we have a solution in the draft/

olivier: kawai is going to take us through the web midi session at NAMM.

kawai: thank you.

Report on Web MIDI Session at NAMM

kawai: I want to talk about the organisation at the meeting.
... there was an organisation that represents Japanese manurfactures.

<cwilso_> kawai: two organizations involved: AMEI, which is only active in Japan, and MMA, which covers the rest of the world.

kawai: the meeting was January 22-26.
... the show is very big, with many instrument companies visiting, so these two orgs meet after the NAMM show.
... there was a demo of Web MIDI and the Web MIDI API.

<cwilso_> slides I presented at this meeting: http://webaudiodemos.appspot.com/namm/

<kawai> http://1.bp.blogspot.com/-lWVyAsQp4gU/Utzh4asS0iI/AAAAAAAAVHw/qrvc6sZfRLk/s1600/400598_347039785437621_1009547038_n.jpg

kawai: Some stickers that we distributed.

<olivier> MIDI API character stickers

<cwilso_> (that picture is MIDIappy, the Web MIDI mascot :)

kawai: we talked also about using sysex messages in the web browser too.
... and the last one was about the issue of javascript in the browser and the fact that it is easy to steal the code.
... I don't think there are opinions that we need to track. Could you repeat the 2nd question?

olivier: the question was: we know that we've been asking people to send messages of support about the Web MIDI API. I assume that we've been requesting that people send email to our list, or talk to vendors directly.
... but to what extent should we track these testimonials / messages of support?
... cwilso_ do you have an opinion?

cwilso_: kawai is working with some other partners to help with an implementation, so that mozilla have some data to decide whether it's worth implementing in the web platform.
... among the web developer community there may not be too much knowledge about web midi, but within the broader community of music hardware manufacturers there's a lot of interest.

cwilso_ mentions https://github.com/yamaha-webmusic/nsx1-apps/

(yamaha open source app that uses web midi)

olivier: it might be useful to ask AMEI and MMA to send messages of support on behalf of their members to browser vendors.

cwilso_: yes, that's what I'd like to see.

olivier: do you need any support?

cwilso_: I'm happy to push on it, and kawai and I will be working together on this.

shepazu: we've had this problem before - trying to prove to browser vendors that there's interest in doing something. SVG is a good example, but it's not the only one.
... with my dev-rel hat on, I wonder if there's something more systematic that the W3C could be doing to help inform the browser vendors that there is an interest in something that has a specific application
... cwilso_ are you happy with how things are going? And do you need some more help?

cwilso_: I expect browser vendors will decide what they do and don't want to prioritise. The problem here has been showing to vendors that there are developers who are not currently on the web platform who really want to be there.
... walking around NAMM it is clear that there's lots of applications out there that are using propriatory technology when there's no reason at all that it couldn't work on the web platform.

cwilso mentions a PianoMarvel

thanks

cwilso_ and shepazu are going to talk about this some more.

Visible data races (and scriptprocessornodes in workers)

<olivier> https://github.com/WebAudio/web-audio-api/issues/66

<olivier> https://github.com/WebAudio/web-audio-api/issues/268

olivier: what we're talking about here is GH issue 268 which we talked about last time.

<olivier> action-92

<trackbot> action-92 -- Chris Wilson to Report on exploration of performance impact of github issue 268 -- due 2014-02-20 -- CLOSED

<trackbot> http://www.w3.org/2011/audio/track/actions/92

cwilso: the short version of my suggestion, saying that we're going to create new buffers for every call to onaudioprocess is going to put a lot of pressure on memory allocation, where there's already a lot of pressure. I don't have a great solution to that.

<joe> I'm saying that the question of getting scriptprocessornodes off the main thread is actually a higher priority and the memory issue (coupled to the main thread) feels like a distraction

olivier: my concern is this is creating a bit of a web of dependencies
... I think I agree with joe that the priority is the workers issue, but do you have the bandwidth to take it on padenot and cwilso ?

padenot: yes, I think we can start talking about it.

<olivier> https://github.com/WebAudio/web-audio-api/issues/113

padenot: and defining the right scope.

olivier: I think this ^^ is the scope.

<olivier> message from Joe

cwilso: I think this issue is pretty important. I'll take it on.

olivier: I'm happy for you two to work on it together, I just want a point of contact.

cwilso: that's fine.

<olivier> ACTION: cwilso to draft strawman proposal(s) on scriptprocessornodes in workers - see Github issue 113 [recorded in http://www.w3.org/2014/02/20-audio-minutes.html#action03]

<trackbot> Created ACTION-96 - Draft strawman proposal(s) on scriptprocessornodes in workers - see github issue 113 [on Chris Wilson - due 2014-02-27].

next meeting

olivier: I think we'll skip item 4 for today, and put it to the top of the agenda next time.
... two weeks from now is the 6th March. Any regrets, or are we happy with the 6th?
... 6th March it is then.
... adjourn (on time!)
