Abstract
An audio capture apparatus comprises a first beamformer () which is arranged to generate a beamformed audio output signal. An adapter () adapts beamform parameters of the first beamformer and a detector () detects an attack of speech in the beamformed audio output signal. A controller () controls the adaptation of the beamform parameters to occur in a predetermined adaptation time interval determined in response to the detection of the attack of speech. The beamformer () may generate noise reference signal(s) and the detector () may be arranged to detect the attack of speech in response to a comparison of a signal level of the beamformed audio output signal relative to a signal level of the at least one noise reference signal.
