<p>A communications system (10) transmits a near end digital signal using a compression code comprising a plurality of parameters including a first parameter. The parameters represent an audio signal comprising a plurality of audio characteristics. The compression code is decodable by a plurality of decoding steps. The system also transmits a far end digital signal using a compression code. A terminal (20) receives the near end digital signal, and a terminal (36) receives the far end digital signal. A processor (40) is responsive to the near end digital signal to read at least the first parameter. The processor generates at least partially decoded near end signals and at least partially decoded far end signals. Based on such signals, the processor adjusts the first parameter and writes the adjusted first parameter into the near end digital signal. Another terminal (22) transmits the adjusted near end digital signal. As a result, the echo in the near end digital signal is reduced.</p> |
