A noise reduction filter would be a very good function.
What the filter is doping, it's taking a sample of the noise print in your microphone signal and removing after a few seconds all the background noise from fans etc. I have tried it on other platform and it works really good.
It would eb a very good option when voice is used to have it and people can optional turn that on. Because it can take a little bit cpu. Not sure how much.
