Abstract:
A method, apparatus and computer program wherein the method comprises: obtaining a beamforming signal using respective signals from a first microphone and a second microphone; reducing the data size of the beamforming signal by grouping the beamforming signal into frequency bands and obtaining a data value for each of the frequency bands; and forming a bit stream comprising at least the reduced size beamforming signal and the signal from the first microphone wherein the bit stream enables parameters of a beamed audio channel to be controlled.
