[IOS] onCurrentRecordingWaveformData returns currentDecibel with delay

[Bayramito]

onCurrentRecordingWaveformData returns incorrect values.

I speak fast to test and say "HEY" and the values are like this

this is the output visualization of saying just "HEY"

But on Android the output looks like this

As you can see values are jumping from 0.01 to 0.6 which is fine, but returns to 0 slowly. I have no idea what can cause this, but it works fine on Android.

UPDATE: tried to remove linear function in native side, but did not work

@Bayramito how do you access native events like onCurrentRecordingWaveformData?

@Bayramito how do you access native events like onCurrentRecordingWaveformData?

there are some hooks provided, if you check the core files. useAudioRecorder and useAudioPlayer via these...
