Abstract
An apparatus including circuitry configured to: obtain at least two microphone audio signals; determine audio data including different directivity configurations that are able to capture sound from substantially a same or similar direction; determine at least one value related to the sound arriving from at least the same or similar direction based on the audio data; determine further audio data including at least one configuration which provides a more omnidirectional directivity configuration than the audio data; determine at least one value related to the sound based on the further audio data; and determine a noise suppression parameter based on the at least one value related to the arriving sound and the value related to the sound. The spatial noise suppression parameter is configured to be applied to the microphone audio signals in the generation of a playback audio signal.
