How to reduce noise for microphone

[Sawanya000]

I experimented with the settings for noise reduction and SoundMinLevel and SoundIgnoreInterval but it also has noise. What should I do?

Noise reduction is turned on by default, RVMicrophone.NoiseReduction = True.

RVMicrophone.SoundIgnoreInterval allows to ignore sound if its amplitude is the same for some period of time.
RVMicrophone.SoundMinLevel allows to ignore too quiet sound.
These two options usually work in time intervals between speech.

If you still can hear noise, that means that our algorithm cannot suppress it, sorry.

Hi, I have been set noise reduction already but it still has noise. Whatever I set noise reduction or not, it has the same result.
