1. A device comprising:
a memory configured to store instructions; and
one or more processors configured to execute the instructions to:
determine a first phase based on a first audio signal of first audio signals;
determine a second phase based on a second audio signal of second audio signals;
apply spatial filtering to selected audio signals of the first audio signals and the second audio signals, wherein the spatial filtering is applied to a first subset of the selected audio signals to generate a first enhanced audio signal, and wherein the spatial filtering is applied to a second subset of the selected audio signals to generate a second enhanced audio signal;
select one of the first enhanced audio signal or the second enhanced audio signal as an enhanced audio signal;
generate a first output signal including combining a magnitude of the enhanced audio signal with the first phase; and
generate a second output signal including combining the magnitude of the enhanced audio signal with the second phase, wherein the first output signal and the second output signal correspond to an audio zoomed signal.
