1. An apparatus comprising:
at least one processor; and
at least one non-transitory memory including computer program code;
the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
determine at least one spatial parameter based, at least partially, on at least one input audio signal captured with at least one first device, wherein the at least one input audio signal is configured to represent at least a portion of an audio scene;
identify a portion of interest of the audio scene based, at least partially, on the at least one spatial parameter;
generate at least one first audio signal based, at least partially, on the at least one input audio signal;
select at least one external audio signal based on:
a determination that the at least one external audio signal is configured to represent, at least, the portion of interest, and
a location of one or more microphones, configured to capture the at least one external audio signal, in or near the portion of interest;
generate at least one second audio signal based, at least partially, on the at least one external audio signal, wherein the at least one second audio signal is configured to represent, at least, the portion of interest of the audio scene; and
combine, at least partially, the at least one first audio signal and the at least one second audio signal into at least one combined audio signal, wherein the at least one combined audio signal is configured to, when rendered, create a reconstructed audio scene.
