Set a fixed listening position #23

Closed burnzzz closed 6 years ago

burnzzz commented 6 years ago

I am researching if it is possible to use the 7 mems mic array in a fixed installation and set it to a fixed listening direction. I see the get_direction() method, but would it be possible to focus the mic array beam to a fixed position?

In my scenario I know where the speaker is and I want to suppress as much background noise as possible. Would be happy t get a hint in the right direction.

You should have a try of the ODAS project
