How does the microphone on a MacBook not cause feedback?

871 views

On a MacBook, I can be in a Zoom Meeting and speak into the MacBook Mic, while also listening to the meeting via the MacBook speakers. How is it possible for the mic to only receive my voice (and not also the sound of the meeting coming out of the speakers)?

The computer knows what should be coming out of the speakers and they can essentially erase that from the signal coming back from the mic.

Connect another device to the call next to the mac and have the audio on both. You’ll have echo going on immediately.
