ABSTRACT:
Classifying signals includes receiving signals from communication devices, where each signal is received from a communication device. The following is repeated for each signal: a received signal from the communication device is encoded, whether the encoded signal is an undesirable auditory signal is determined, and the encoded signal is modified if the encoded signal comprises an undesirable auditory signal. The received signals are combined.
