ABSTRACT:
A multipoint communication apparatus receives a set of audio signals encoded by gain-shape vector quantization. A gain detector in the multipoint communication apparatus dynamically selects a subset of these audio signals on the basis of gain indices contained in the audio signals. Only the selected subset of audio signals are decoded. The decoded signals are combined to produce an audio output signal.
