Abstract
There is provided a clip-on microphone assembly comprising a clip-on mechanism () for attaching the microphone assembly () to the cloths of a user (); at least three microphones () for capturing audio signals from the user's voice, the microphones defining a microphone plane; an acceleration sensor () for generating an orientation signal by sensing gravitational acceleration in at least two orthogonal dimensions, an audio signal processing unit () for producing an output audio signal () from the captured audio signals, comprising a beamformer unit () for processing the captured audio signals, in order to generate the output audio signal, in a manner so as to create an acoustic beam having a direction, a DOA unit () for determining the direction of arrival of sound by analyzing the captured audio signals; and a control unit () for controlling the beamforming unit, the control unit being adapted to determine an allowed angular sector () of the direction of the acoustic beam according to the orientation signal and to steer the direction of the acoustic beam within the allowed angular sector according to the determined direction of arrival.
