Abstract
A method of generating an audio signal comprises receiving a plurality of input audio signals from a plurality of microphones forming a microphone array, the plurality of input audio signals being representative of a set of sound sources within the auditory field of view of the microphone array at a given instant in time; receiving a motion input signal from a motion sensor, the motion input signal being representative of the motion of the microphone array; and manipulating the received plurality of input audio signals in response to the received motion input signal to generate an audio output signal that is representative of a set of sound sources within the auditory field of view of a virtual microphone, the apparent motion of the virtual microphone being independent of the motion of the microphone array.
