Patent ID: 8423358

Claim:
A method for creating an output signal in response to determining one or more unexpected packets, where an unexpected packet includes a packet that is lost, corrupted, erased or delayed, and where an expected packet includes a packet that is not lost, corrupted, erased or delayed, the method comprising: generating at least one synthesized audio signal segment corresponding to at least one unexpected packet; determining a length of an overlap-add window to use in combining the at least one synthesized audio signal segment with a subsequent audio signal segment resulting from an expected packet being decoded by a receiver, wherein the expected packet is received subsequent to the at least one unexpected packet, wherein the length of the overlap-add window is determined based on a length of an erasure encompassing the at least one unexpected packet; and performing an overlap-add operation on the at least one synthesized audio signal segment and the subsequent audio signal segment using the determined length of the overlap-add window.
