Claim 16:
17. The method of claim 15, wherein the four-state state machine comprises an un-binauralized holding state, UBH, a binauralized holding state, BH, a binauralized release counting state, BRC, and a binauralized attack counting state, BAC
wherein UBH and BAC correspond to the state signal indicating that the current audio frame is in an un-binauralized state and BH and BRC correspond to the state signal indicating that the current audio frame is in a binauralized state; and
wherein the state transitions from UBH to BAC upon the confidence value being above a confidence threshold, the state transitions from BAC to BH upon a threshold number of frames having a confidence value above a confidence threshold while the state is BAC being reached, the state transitions from BH upon the confidence value being below a confidence threshold and the state transitions from BRC to UBH upon a pre-determined number of consecutive frames having a confidence value below a confidence threshold.
