Mavic air records also audio over the cached low quality video located on the phone. The audio quality is also very low quality( 64kbps ) Is there any adjustments or way to increase this audio recording quality ?
I've never come across it. I've used a voice recorder app before, on Android it's called Smart Recorder. In that app you can control the audio quality from 8khz up to 44.1khz (CD Quality).
Don't tell me you really never did go through the menus of the app? Using the forum for even the most simple things can be dangerous, since you can never be sure of the quality and correctness of the answers...
