I can think of some commercial audio processors that can help with that, but they are super pricey.
I can’t think of a linux application that has this capability. If there is something out there that offers AEC (acoustic echo cancellation) on linux with two mic inputs, id also be interested.
One way to help with this as far as inexpensive hardware is to make sure you’re using cardioid dynamic microphones, and not omnidirectional condenser microphones. Cardioid dynamic mics generally pick up audio directionally, like from the “front”. You have to be right up on the mic in order to have it record any type of audio. They generally wont pick up environmental sound from anything more than a few feet away. You can just point them away from noise you don’t want to pick up.
