Background audio can reveal where a video was recorded

100 meters may be close enough for this background audio privacy risk, as aircraft sounds can help locate videos. See what the evidence shows

When uploading a real recording, there is a good chance your location & therefore possibly your identity can be revealed from the footage itself.

  1. You can triangulate low volume background sounds such as air planes: https://cybernews.com/privacy/aircraft-doppler-audio-geolocation-privacy/

  2. You can check the position of the sun/moon/stars, shadows, weather…: https://www.bellingcat.com/resources/2020/12/03/using-the-sun-and-the-shadows-for-geolocation/

If Streamers & Journalists CAN do it, government agencies ARE doing it.

If you need privacy be aware of this when recording / editing friends <3

    Video only demonstrated that high-pass filtering doesn’t work. If you (or that hypothetical software) know where you are and at what time you recorded, you’ll know exactly where those ミ lines are are gonna be, so you’ll only need to erase them and fill them with noise indistinguishable from rest of background.

    And just in case your noise model is not good or seams aren’t that well hidden as you think, make it look like you erased a bunch more plane sounds in other paces on recording, so that there are thousands of places you could be in (picking should be weighted with population density)
