ABSTRACT:
A communication device, has a receiver for receiving an audio signal, and an apparatus for producing a signal that is representative of the audio signal. A first analyzer analyzes at least a portion of the representative signal to determine whether the portion of the representative signal belongs to a predetermined category. The communication device also includes a transmitter that transmits a signal having an audio portion, with holes placed therein, and a first signalling information indicating whether the portion of the representative signal belongs to the predetermined category. A second analyzer analyzes the portion of the representative signal to determine at what times to place holes in the audio signal.
