Abstract
A method of mixing microphone signals. First and second microphone signals are obtained from respective first and second microphones. In at least one affected subband, the first and second microphone signals are mixed to produce first and second mixed signals. At least one reference subband of the first and second microphone signals is processed in order to identify a binaural cue between the first and second microphone signals, the reference subband being distinct from the or each affected subband. The affected subband in the first and second mixed signals is modified in order to re-emphasize the identified binaural cue.
