Bad stuttering in webaudio_orientation on Chrome

[looeee]

The webaudio_orientation example has extremely bad stuttering on Chrome for Android.

The example seems fine on Edge and Firefox (desktop) and Firefox (Android). Other audio examples are not stuttering on Chrome, that I noticed.

After testing on my Pixel 1 and Chrome (72.0.3626.96) I've noticed a stuttering sound especially when entering/leaving the directional cone.

It seems @looeee 's Chromium bug report was actually classified as a bug. So this issue might get fixed on the browser side.

Sorry for the late response. Do you all believe this is a regression? Then we need to find the offending revision.

Um, I'm not sure. But I can't remember such a stuttering when implementing webaudio_orientation last summer (#14243) and when we introduced the usage of linearRampToValueAtTime() via #14393.

BTW: The stuttering also happens in Chrome 72.0.3626.109 on macOS 10.14.3 when you move some time the camera in webaudio_orientation.

@Mugen87 Could you file a bug with a simple repro case on crbug.com? Here's a shortcut for the webaudio bug template.

@hoch There was already file a bug by @looeee right here:

Thanks! Will look into it soon!

Hmm, this was closed as "won't fix" 🙁
If anybody else can test it and still gets the same behaviour, please report that on the Chromium bug linked above. Otherwise, we may be stuck with this for some time.

Just added a couple of comments 🙂

@Mugen87 Just to confirm, when the camera is behind the wall, we shouldn't hear any sound, correct?

I still hear it, though attenuated, on FF desktop.
