A system and method for the concealment of errors resulting from missing
or corrupted data in the transmission of audio signals in compressed
digital packet formats is disclosed. The system utilizes a circular FIFO
buffer to store audio frames from the transmitted audio signal, and a
beat detector, to identify the presence of beats in the audio signal. The
error concealment method replaces erroneous audio frames with error-free
audio frames by a process which takes into account the presence and
location of the detected beats.
