Is there a way to increase/decrease the input volume of the Android microphone. I did some research on Google as well as StackOverflow but didn't find a suitable answer.
Here are some links:

How to adjust microphone volume in android?

Adjust Microphone Recording Volume

Is Android capable of managing microphone/input volume?.

Please provide any help/reference.

I had a certain problem where I had to increase the volume (gain) of the sound and also filter out some frequencies I used TarsosDSP library for android it has a particular class called GainProcessor where you can adjust the sound accordingly. Hope it helps.
