Abstract
A method of error protection for wireless communication of packets of sampled digitized audio data according to a selected communication protocol, comprising: identifying the least significant bits of each sample of audio data encoded in the packets based on the communication protocol used; selectively replacing one or more of the least significant bits with values that enable performing error correction on the rest of the data encoded in the packet; transmitting the altered packet from a transmitting party to a receiving party; using the replaced bits to detect or correct errors in the transmitted packet; wherein said communication protocol uses an ADPCM encoding scheme.
