Recover sound from video. For real!


The guys at BI released an amazing news recently> you can now recover sound from plain videos. You may need to first record those videos with a high-speed camera, but you will be able to get sound out of there even if the videos are muted. Really.

Abe Davis and his team at MIT Labs have created a process in which they can actively recover 2.2Khz sounds from videos takes without sounds. They use software to check the vibrations of objects as they come in contact with the sound and then extrapolate that info to obtain sound. Get it? Look at the vibrations and you will find the sound. It is incredibly clever in its simplicity.

They are working now on methods to recover sound from regular cameras that run on 60fps as opposed to the high-camera that run on 6k fps. Cool, ain’t it?
