1. A system, that includes a first earpiece that includes one or more microphones and a second earpiece that includes one or more microphones, comprising:
a memory; and
one or more processors coupled to the memory, the one or more processors configured to:
generate a spatial audio record;
detect an occlusion of a first microphone of the one or more microphones on the first earpiece or a second microphone of the one or more microphones on the second earpiece associated with at least one audio frame of one or more audio frames associated with the spatial audio record, wherein the spatial audio record is a stereo audio record that includes a first audio channel associated with the first microphone and a second audio channel associated with the second microphone; and
select, based on the detection of the occlusion, at least one of an occluded spatial filter for the one or more audio frames or a non-occluded spatial filter for the one or more audio frames; and
select, the first microphone included on the first earpiece based or the second microphone included on the second earpiece, based on the detection of the occlusion.
