Excuse me, *2JV* circuit.

yeah, that's all possible

it's just magnitude filtering

Interesting

frequency filtering is something else

multiple people speaking in the same frequencies

and plenty of noise there as well

doesn't exist

I'm telling you this because I'm working on it. If it existed, my job would be done.

at least two vantages to it

one, be able to separate the frequencies

two, be able to get the frequency in the first place

that's where the lasers come in

you can test this with microphones easily

that's the first part

record a bunch of stuff and figure out how to separate it

second, figure out how to do it without microphones

laser intensity is affected by vibration

nope

well, that could work

but you'd have to get the microphone close enough

what if you could just point a laser from a distance

If a laser can detect the same vibration that a microphone does, but doesn't have to be close.....

okay, so call it a microphone that doesn't need to be in the room

if you want semahtics

the point is, the device can be miles away

without getting into the grit, laser intensity if affected by micrometers of variation of distance, the kind of variation that comes from a surface vibrating from being impacted by the human voice4

the same vibration that microphones use can be detected from distance

there are limits

it's sinusoidal

goes between 1 and 0

too much variation can mean you go from 0 to 0

so you don't hear anything

the point is, this is widespread research

I'm not special in being a part of this

not at all

we got closer today than we've ever been, and we've only been working on it for a few weeks, and I've been reading the works of everyone else already working on it

it's all public

it isn't even hiden in our prompt

well maybe it was in the early stage

I'm in the third stage
