Get an angle from Acoustic SL library?
Hello!
I am working on a project I have 4 mems microphones and I want to get an angle from these 4 microphones, I have 12 neopixel Leds which lit up according to the voice direction on the 4 microphones. I have the Stm32cubeide project for it, but I don't how can get the angle with it.
Here is the Code and I will also attach the files...
Please guide me!
