how do microphones in a phone not pick up any audio that the speakers put out? if I put a call on speaker mode, how do people on the other end not hear themselves?
In: Technology
Won’t read the replies but I’ll add some little fact:
Audio is highly digital these days, meaning what the other part hears ain’t nothing like a 1×1 voice connection, and yes the byproduct of noise cancellation tech such as mixing and stabilizing multiple microphone sources and applying other hardware/software optimizations such as compression so fast and with such efficiency it happens in what gives us the impression of a real time conversation. Kinda like why phones come with multiple cameras instead of a single one, they’re all working in tandem to construct the illusion of a great camera.
This technology is being expanded for video, in initiatives such as Google’s Starline https://blog.google/technology/research/project-starline/ where again, SEVERAL components are working in amazing speed to give the illusion of real time talk, by emulating what we perceive as real time.
