Describe the issue you are experiencing
Whilst there are clear options for gain and microphone multiplier - there seems to be no easy way to capture some of the audio AFTER these parameters are applied to see how well the microphone is performing and whether it is distorting, too quiet or other problems may be occurring.
So getting good quality seem to be a case of juggling gain and microphone volume multiplier, turning on logging in Whisper to see what transcribed text comes through and guessing whether it's too soft, too muffled, or distorted etc.

After many hours, I chose:
Noise suppression: 0
Audio gain: 12
Microphone volume multipler: 32 (yes this high!)
