The article quite literally is about a technique to bypass that limitation and do it with a regular 60fps camera.
- maxerickson 8y agoIt sounds like that technique doesn't quite recover the audio though, just a portion of it: While this audio reconstruction wasn’t as faithful as that with the high-speed camera, it may still be good enough to identify the gender of a speaker in a room; the number of speakers; and even, given accurate enough information about the acoustic properties of speakers’ voices, their identities. Saying it may still be good enough pretty strongly implies that the quality is quite low.
- RugnirViking 8y agoThere is a video on the webpage that includes the recovered audio. It is low quality, but enough to understand the speaker most of the time, and definately enough to pose a security risk when analysed by a specialist
- maxerickson 8y agoThe youtube clip in the article? The voice reconstruction there is from high speed video. If you mean some other video, I'd appreciate a link.
