Hi all,
So today I did some testing with adding wind protection to the microphones on my GoPro 11. While doing this, I discovered that if you put a piece of tape over the "microphone drain cover" so that it is closed off and air sealed, the recorded audio goes completely bonkers and seems to lose a major part of the audio signal.
So I suspect that this drain cover has more important functionality than just draining water. Perhaps it has some kind of interference tube-like function seen in shotgun mics? If anyone can explain what the actual mechanism is, I'd be very interested to hear it. All I can tell is that this is definitely not just for draining water
If you want to test this yourself, just record a clip while speaking to the camera and put a piece of tape over the mic drain cover. You should hear the effect when you play back the clip on your computer.
Note that I have wind: off and raw audio: low. Both the mp4 file and the wav file is affected by this.
