I use a Mobius camera (original variant - https://www.mobius-actioncam.com/) mounted on my rollbar and while it has great picture quality, is inexpensive, easy to integrate with my data system (automagically turns on on poweron, so automatically in sync with my traqmate data), the audio is terrible -- looking at the WAV data, I can see the samples are severely clipped - I guess our chick car engines are just too loud? I can't find any software settings to control this (the only audio-related setting is On/Off - nothing to control input gain).
A bit of googling revealed a youtube post claiming to reduce wind noise by opening up the camera and fitting some foam ear pads around the mic -- maybe something like that could attenuate the signal enough to help?
I know others are using Mobius -- do you have any tricks/tips for getting better audio?
