Minutes

   -

   16:00-16:10 UTC (9:00-9:10 am PDT): Set up calls
   -

   16:10-16:30 UTC (9:10-9:30 am PDT): NoiseGenerator
   <https://github.com/WebAudio/web-audio-api-v2/issues/8>
   -

      [Raymond briefly describes API]
      -

      Michel: What about colored noise?
      -

      Raymond: No support for that; there’s no generally accepted method
      for this that I could find.
      -

      Jeff: The output values are cross-browser equivalent?
      -

      Raymond: Yes, the node and RNG is specified so that you should get
      exactly the same output for the same seed and sequence for the uniform
      generator.  The gaussian generator may produce different values because
      there are many many different ways to do that.
      -

      Michel: What is the actual use case?
      -

      Raymond: Don’t actually know other than the request.
      -

      Michel: See https://faustlibraries.grame.fr/libs/noises/
      -

      Jeff: ruth posted this in slack: https://studio.rumyra.com/newnodes/
      -

      Michel: Should specify the generator code?
      -

      Raymond: It’s pcg, but could be others like the one used in
      Javascript (xoroshiro)
      -

      Michel: Can we propose more?  Colored noise; using your own generator.
      -

      Jack: In that case should this be in a worklet?
      -

      Raymond: We’re not opposed to adding more types; just need to have
      some well-known good methods for colored noise.
      -

      Michel: The Faust code has references to how to generate different
      types.
      -

      Raymond: Please propose new things since you have a lot of experience
      with this in Faust.
      -

      Michel: I’ll take a look again and propose something.
      -

   16:30-17:00 UTC (9:30-10:00 am PDT): Automation with power law
   <https://github.com/WebAudio/web-audio-api-v2/issues/22>
   -

      Michel: Talking to people from the native audio world, no one will
      want to use AudioParams
      -

      Michel:  Linked to a document containing a critique of AudioParams.
      -

      [Raymond:  Document isn’t completely public, so no link to it here,
      but is available to WebAudio members.  Please ask Michel if you
want to see
      it.]
      -

      Jack: I understand the criticism but also understand the historical
      view.  Things have changed a lot since the beginning of webaudio.
      -

      Jack: This is probably to fill a gap in what novice users see with
      plugins that have these kinds of wave shapes.  This is useful for them.
      -

      Raymond: It’s relatively easy to add and the specification is
      straightforward.
      -

   17:00-18:00 UTC (10:00-11:00 am PDT): playbackPosition property
   <https://github.com/WebAudio/web-audio-api-v2/issues/26>
   -

      Jack: I agree with Paul’s last comment.
      -

      Jeff: Yes, and I don’t agree with paulSlocum’s comment about using
      time.
      -

      Jeff: What else needs to be done?
      -

      Raymond:  I think Paul’s proposal is pretty complete.  Not much else
      needs to be done.
      -

      Jack: I think it would be great.
      -

      Raymond: Jack, do you have a need for this?
      -

      Jack: Most definitely.
      -

      Raymond: What do you do now then?
      -

      Jack: We compute the position ourselves using complicated formulas so
      not having to do that would be really nice.
      -

      Raymond: Ah, like what ChrisW says with his wubwub demo.
