16:46:09 <Zakim> ok, trackbot
16:46:10 <trackbot> Meeting: Audio Working Group Teleconference
16:46:10 <trackbot> Date: 02 February 2017
16:46:44 <mdjp> Agenda+ Resolve issues from last call #1105, #1099, #1089, #1079, #95, #13, #10
16:46:55 <mdjp> Agenda+ Issue #1123
16:46:59 <ChrisL_> I reported it when Matt told me, and the systems team fixed it
16:47:02 <ChrisL_> This list was deactivated yesterday by mistake. It is now active again, but all
16:47:02 <ChrisL_> the mails sent between yesterday 20:04 UTC and now are lost.
16:47:02 <ChrisL_> Apologies about that.

17:05:34 <hongchan> hi all.
17:06:33 <joe> hi!
17:06:48 <joe> hongchan, are you guys able to join call this am?
17:08:54 <ChrisL> present+ ray, HongChan, Matt, Joe, Paul, Chris
17:09:05 <rtoyg_m> present+ rtoyg_m
17:09:16 <mdjp> zakim, take up agendum 1
17:09:16 <Zakim> agendum 1. "Resolve issues from last call #1105, #1099, #1089, #1079, #95, #13, #10" taken up [from mdjp]

17:12:23 <jdsmith> jdsmith has joined #audio
17:12:34 <jdsmith> present+ jdsmith
17:13:47 <mdjp> joe what are the remaining decisions to be made padenot agree on features, test and write prose.
17:14:44 <mdjp> ChrisL whats the impace of implementaitons having different smoothing padenot sounds different, one property to guarantee is soft & hard knee
17:15:38 <mdjp> padenot always soft knee is fine the env is easy to spec + computation of gain.
17:16:12 <mdjp> ChrisL default values for gain and delay padenot delay is fixed ChrisL we should spec this as it will effect latency
17:16:51 <mdjp> padenot add audioparam to deactivate delay in some usecases.
17:19:45 <mdjp> padenot if there is no disagreement can continue what I am doing in #10, no disagreement.
17:21:02 <mdjp> joe who takes this forwards padenot 5 stages env, gain, pre delay. Gain computation is the main area or work.
17:21:24 <mdjp> padenot to take this forward.
17:22:19 <joe> https://github.com/WebAudio/web-audio-api/issues/13
17:24:33 <mdjp> joe is approach in #10 suitable for Noise/Gate/ expander - padenot is there a problem when the ratio is <1?
17:26:20 <mdjp> ChrisL 2 options - set of defaults, 2 node based on Compressor joe only thing not suppored in DC approach may be hysteresis
17:28:13 <mdjp> hongchan usecase for expander is more limited than noise gate. Hysteresis issue is more important for noisegate
17:28:43 <mdjp> ChrisL test the current proposal with Dynamics compressor, if it is not suitable then implement improved version in v.next
17:32:31 <mdjp> joe can we incoorporate negative ratio to test this.
17:33:47 <mdjp> joe add expander funtionality to compressor and push noise gate to v.next
17:33:53 <mdjp> general agreement
17:35:25 <mdjp> https://github.com/WebAudio/web-audio-api/issues/95
17:37:35 <mdjp> action to review PR off the call
17:37:35 <trackbot> Error finding 'to'. You can review and register nicknames at <http://www.w3.org/2011/audio/track/users>.
17:37:40 <joe> https://github.com/WebAudio/web-audio-api/issues/1089
17:39:53 <padenot> https://github.com/jernoble/Sound
17:44:17 <mdjp> padenot channel ordering is dependant on the underlying libraries used by the browser.  Channel information is lost in the process. example aac ordering LCR vs SMPTE LRC
17:45:16 <mdjp> jdsmith can we normalise this just for the waapi? padenot yes we could spec to one standard
17:45:52 <mdjp> joe can we assert that when a media element is delivering a file, the channel mapping of the file will be employed
17:47:22 <mdjp> padenot spec for both media element and decodeAudioData
17:47:51 <mdjp> joe Shall we pick SMPTE?  jdsmith will get feeback for next call
17:49:55 <joe> https://github.com/WebAudio/web-audio-api/issues/1099
17:51:54 <joe> https://github.com/WebAudio/web-audio-api/issues/1105
17:53:14 <joe> https://github.com/WebAudio/web-audio-api/issues/1079
17:54:27 <mdjp> joe can we/how do we improve on this
17:56:51 <mdjp> padenot this is informative - gc not observable. Maybe we should make it normative, there is behaviour here which would result in observable changes.
17:57:14 <mdjp> joe why can we not remove the informative label from the lifetime section.
17:57:37 <mdjp> joe same applies to baseaudio context lifetime section which is normative
18:00:27 <mdjp> next call 16th Feb
