16:07:22 <joe> joe has joined #audio
16:08:51 <mdjp> hongchan ian not here today, landed a new introduction and audioworklet section with examples and concept text as suggested by domenic. Planning to add algo for instantiation and registration.
16:09:12 <mdjp> Till waiting for Alex Russel opinion for officical tag response.
16:09:56 <mdjp> hongchan following convention of css spec but it is different from what we have been doing in our spec.  Trying PR first and can revisit after review.
16:10:23 <mdjp> PR available after this meeting.
16:11:19 <mdjp> rtoyg_m we can remove the old audio worker text now. hongchan should we keep it until audioworklet is stable?
16:11:57 <mdjp> rtoyg_m removing section 2.12 now. All agree
16:12:38 <mdjp> zakim, take up agendum 2
16:12:38 <Zakim> agendum 2. "A selection of issues requiring review" taken up [from mdjp]
16:12:56 <joe> https://github.com/WebAudio/web-audio-api/issues/930
16:13:57 <mdjp> rename registerAudioWorkletProcessor -> registerProcessor
16:13:59 <mdjp> agreed
16:14:23 <joe> https://github.com/WebAudio/web-audio-api/issues/475
16:17:36 <joe> https://webaudio.github.io/web-audio-api/#methods-7
16:18:04 <mdjp> hongchan not sure if stop() method should be on AudioWorkletProcessor
16:18:58 <mdjp> joe we need a method scoped to a single node - note terminate() is not
16:19:37 <mdjp> joe should stop cause the associated node to be disconnected.
16:20:06 <mdjp> rtoyg_m in this case stop should work in the same way as it works for oscillators
16:21:38 <mdjp> iank_ in other specs instances are under control of the engine and can be created or destroyed.
16:24:22 <mdjp> joe stop method in the processor would allow termination before prescheduled (tail time) events has completed.
16:24:54 <mdjp> hongchan there is no way for a processor to know if the node is part of the graph or not
16:27:35 <mdjp> joe proposal a; rely on application to communicate via post that the worklet should stop. proposal b: expose on the worklet context info so that conncted inputs can be determined
16:31:01 <mdjp> iank_ another option is to have an optional return value to report that there is still an active tail. eg keep calling until returns false
16:32:31 <hongchan> hongchan has joined #audio
16:34:07 <mdjp> joe nodes that except an input be removed when their input is disconnected - the same managed approach shoould be an option for audioworklet
16:36:44 <joe> q+
16:37:24 <joe> ack joe
16:37:43 <joe> https://webaudio.github.io/web-audio-api/#lifetime-AudioNode
16:38:17 <rtoyg_m> rtoyg_m has joined #audio
16:38:30 <mdjp> joe q about lifetime def which feels ambiguous - states that various refs will perpetuate the node, this is ambiguous with respect to inputs and outputs, was the intent that it only applies to inputs?
16:41:03 <mdjp> we should clarify in the text but this does refer to inputs.
16:43:13 <mdjp> joe offering to put together a PR, but which approach currently feels best.
16:43:31 <mdjp> hongchan where should lifetime info be locaated in the spec - audioworklet or 2.4.4 lifetime section, should be references in both sections
16:43:42 <mdjp> joe propose to expose input state in worklet context info
16:44:00 <mdjp> bool hasActiveInput?
