1. An apparatus comprising:
at least one processor; and
at least one memory including computer 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:
obtain one or more audio signals, wherein the one or more audio signals comprise audio captured with a plurality of microphones;
divide the obtained one or more audio signals into a plurality of intervals;
determine one or more parameters relating to one or more noise characteristics for respective ones of the plurality of intervals; and
control noise reduction applied to the respective ones of the plurality of intervals based on the determined one or more parameters within the respective ones of the plurality of intervals, wherein controlling the noise reduction applied at least comprises:
determining whether to provide at least partially mono audio output or spatial audio output based on the determined one or more parameters.
