- TrainedMonkey 4y agoLaser stuff was a single point. The advantage here is capturing a set of 2d pixels which let you see how signal travels through space. This essentially means a large array of microphones which are next to each other and in perfect sync (which I hear is hard when you try to do this with multiple microphones).
- williamcotton 4y agoIt is hard due to phasing, that is, overlapping audio signals from the same source when summed during mixing can cancel out various parts of the signal. Channels on some mixers have a phase inverter and audio engineers will also move microphones around while looking at a phase monitor.

- pishpash 4y agoInteresting interpretation of this as a high-density high-resolution array! But does it need to be isolated well from movement? Since sound wavelengths are long, so maybe not?
- rcxdude 4y agoThis isn't how the system works. It basically can give you a small number of contact microphones (you need to aim a laser at each point you want to record).
- infogulch 4y agoThis is better quality (see comparisions in the video demo) and it's done with mostly normal cameras, not specialized high framerate cameras.
- anigbrowl 4y agoIt has been, but the quality here is much better. Like, that example might have been good enough for intelligence or legal purposes, this is goon enough for commercial/entertainment purposes. The main headache I see is that it still requires a somewhat expensive and complex camera setup, but I can see that coming within the realms of affordability/standardization quite soon.
