The original research in 2014 is presented well. This article in 2018 butchers the terminology, using "speaker" instead of "microphone".

#9I wonder if this could be applied to normal video and get results useful for any purposes. I realize it would be lower quality, but I feel like it might be possible to detect nearby gunshots on security camera footage that doesn't have audio. How cool would it be to see a murder trial enter audio recovered from footage of a house plant as evidence?
