Strange values in Safari when mic volumen is 0

[ibc]

• Safari Technology Preview in OSX High Sierra.
• Mute the mic volume.
• Check the dBs value in "volume_change" event:

It decreases until ~-500 and, after that, it becomes -100 (constant). It never reaches -Infinity.
In the other side, in Chrome/Firefox in behaves differently: it decreases gradually to -Infinity.

Not sure if hark may do something to "normalize" it. Currently it's so hard to detect "muted microphone".

@ibc Are you still interested in this repo? Sorry for the lack of responsiveness. If so, could you verify that this is still the case in the latest version of Safari?

Hi @xdumaine, yes I am. I will re-check it on next days (cannot provide a proper ETA but it will happen in no more than a few weeks).

Is there any news regarding this issue?
I'm encountering the same issue on iOS Safari.

Events were not working for me at all in iOS Safari, my fix was creating a new AudioContext() in a click handler and saving it to a variable to pass to hark later on. If using AudioContext outside of a user interaction, the AudioContext volume seems to break on iOS https://bugs.webkit.org/show_bug.cgi?id=177292
