1. A receiver for receiving wireless packetized audio signals having packet headers, and packet payloads including encoded audio signals, the receiver comprising:
an audio decoder decoding the encoded audio signals into decoded digital audio signals;
an audio error detector detecting impulsive noise in said decoded digital audio signals caused by corrupted payload packets; and
a digital signal restoration unit removing said impulsive noise and reconstructing a digital audio signal corresponding to said corrupted payload packet.
