Detecting sound in background

[lightwolfz]

Is it possible to detect sound level when app is on the background or when screen is locked?
I tried to use the library with react-native-background-timer it work but only after a minute it's only
return rawValue: 0, value: -160 is there anyway to solve this?

I haven't ever tested tested this, to be frank. What platform did you try it on? I'm not a guru of iOS, but on Android I don't think there are any hinders for background audio signal acquisition.

I used it on Android it was fine when testing with the emulator but not seems to work on my device.

Any ideas?

@lightwolfz no ideas, sorry man. What I thought could be the reason is that react-native-background-timer fires only in a specific moment of time and during the rest of the period no data is collected. And measurements are averaged over a period of time. However this doesn't explain why does it still work in the emulator.

If you have any clues please write them here. I'd be very thankful.

I'll keep working on it. I'll post the solution here if I have more information. Thanks for your support 😄
