100% yes and this is why every drone video ever has music over it.
- lacraig2 5y agoThey might be able to pair the video from the drone with the microphone on your phone and get something reasonable (if the drone is far enough away).
- firmnoodle 5y agoIf they can put a dog nose and tongue on a video with AI, I would guess maybe removing the sound of the drone is possible.
- powcontech 5y agoAI is not even required, it would be quite easy to filter out the frequency of the noise from the rotors using technology that has existed for decades if not almost 100 years, indeed Butterworth was designing his filters in the 1930’s
- jjkaczor 5y agoIf I were a drone manufacturer of this type of camera drone, I would release free/downloadable audio profiles/captures of my drone operating at different speeds, to allow filtering to remove them based on the flight profile... (Maybe keep a log of propeller speeds, sync'd to the video)
- pavlus 5y agoSimple FIR filter won't do the job, noise from the rotors and moving air is wideband and overlaps with signal. But adaptive filters used in noise-cancelling headphones with separate mics may work. One directional microphone records sound from the scene, the other undirected one records sound of the drone, then filter tries to minimize drone sound component in the signal from the mic by adjusting coefficients of the filter.
- devmunchies 5y agonot just drone vids, pro video (e.g. hollywood) all add sound in post. Foley Artist is a fun job. A solution would be to have Snap™ mics that i clip on to my shirt and it syncs with the video while recording.
- chaps 5y agoWhy would they clip? Surely they should snap onto your shirt.
- devmunchies 5y agoat first i thought you were being pedantic somehow and then I got the joke.
- sahila 5y agoNo need for an external mic if they can just use your phone app + mic.
- mikeryan 5y ago100% yes and this is why every drone video ever has music over it. That and even without the buzz anything most drones picked up would not be meaningful sound. Most are too far away and moving too much to pick up voices, better to just record off your phone to get conversation and/or ambient noise. I'm almost surprised they even put a mic on this thing, though I'm sure from a product marketing perspective people would ding them for not having one.
