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:
obtain, from a first capture device, at least one first audio signal based, at least partially, on at least one first microphone signal;
obtain at least one first direction parameter for at least one frequency band of the at least one first audio signal;
obtain, from a second capture device, at least one second audio signal based, at least partially, on at least one second microphone signal;
obtain at least one second direction parameter for the at least one frequency band of the at least one second audio signal;
obtain a first position associated with the first capture device;
obtain a second position associated with the second capture device;
determine a distance parameter for the at least one frequency band in relation to the first position based, at least partially, on the at least one first direction parameter, the at least one second direction parameter, and the second position; and
enable an output and/or store of at least one audio signal associated with the at least one first audio signal, the at least one first direction parameter and the distance parameter.
