Patent ID: 7069208

Claim:
A method for concealing errors detected in an input digital audio bit stream, the audio bit stream configured as a series of frames, said method comprising the steps of: detecting a first beat and a subsequent plurality of beats in the audio bit stream; defining a first inter-beat interval extending between said first beat and a (k+1) th subsequent beat; storing at least a portion of the audio bit stream occurring within said first inter-beat interval; detecting an erroneous audio segment occurring in a second inter-beat interval extending between said (k+1) th beat and a (2k+1) th subsequent beat; and replacing at least a first part of said erroneous audio segment with a corresponding part of said stored audio bit stream portion, wherein the corresponding part is selected based on a time relationship between the first part and one of the (k+1) th and (2k+1) th beats.
