Attendees: Jeff Switzer, Ruth John, Christoph Guttandin, Chris Lilley, Raymond Toy, Jack Schaedler Minutes: - V1 - Next steps for V1 - Chris Lilley: Show two implementations pass tests, create report on test passes, and see if director agrees. wpt.fyi can be good enough for the report. - Christoph: Would nodejs count? - Chris L: Yes! - Raymond: no obvious gaps in testing based on wpt.fyi. - Chris L: Looks good. - Raymond and Chris to work on the report. - New editorial issues - Raymond: Summarizes issue - V2 - Pulse width oscillator <https://github.com/WebAudio/web-audio-api-v2/issues/7>. - Raymond: Should it be a type of oscillator or a separate node? - Jack: Yes. a separate node. - Raymond: links to andy.harmon demo <https://github.com/pendragon-andyh/WebAudio-PulseOscillator>. - Chris: Only works if wave shaper is bandlimited - Raymond: I don't think it is, in general. - Conclusion: Use a different node, called PulseWidthOscillator. - Attributes: frequency, detune, pulseWidth (range 0 to 1). 0 is silent, 1 is 1. - Chris: Should be bipolar instead of unipolar. - Raymond: will update issue with proposal for node. - Bring your own buffer <https://github.com/WebAudio/web-audio-api-v2/issues/4> - Jack: From last time, a profile would be very useful to see what the cost would be. - Raymond: V8 has good profiling tools but I need to look it up. - Jack: Will try to profile using Chrome's tracer. - Raymond: Will find the V8 profiling tools - Selectable render size <https://github.com/WebAudio/web-audio-api-v2/issues/13> - Jack: This is important on Android. - Jeff: another fingerprinting issue - Jack: 2 primary cases: optimize for HW (Android) for better CPU usage or large sizes to process large chunks at once where latency isn't an issue. - Conclusion: Work on API proposal, allowing user to specify that the HW size should be used, but also allow setting larger sizes. Some constraints on values need to be specified too. - AOB - Virtual F2F meeting to be arranged sometime around TPAC 2020 in October. Dates/times TBD, but similar to virtual F2F in June.
