Abstract
A machine learning model can determine output frequency response at different directions relative to a target audio output format, based on input including frequency response at directions relative to microphones of a capture device. A spatial filter determined based on the output frequency responses is applied to one or more of the microphone signals to map the spatial information from the microphone signals to the target audio output.
