Claim 2:
3. The method of claim 1, wherein the synthesized concealment audio frame comprises at least two consecutive concealment subframes and wherein deriving the phase adjustment, applying the phase adjustment, applying the time reversal and combining the phase adjusted peaks are performed for a first concealment subframe of the at least two consecutive concealment subframes, the method further comprising:
deriving a phase adjustment to apply to the peaks of the signal spectrum for a second non-time reversed concealment subframe of the at least two consecutive concealment subframes;
applying the phase adjustment to the peaks of the signal spectrum for the second non-time reversed subframe to form non-time reversed phase adjusted peaks;
combining the non-time reversed phase adjusted peaks with a noise spectrum of the signal spectrum to form a combined spectrum for the second concealment subframe; and
generating a second synthesized concealment audio subframe based on the combined spectrum.
