1. A method for controlling a concealment method for a lost audio frame associated with a received audio signal, the method comprising:
obtaining at least one bin vector of a spectral representation for at least one tone, wherein the at least one bin vector includes three consecutive bin values for the at least one tone; and
responsive to whether each of the three consecutive bin values has a complex value or a real value, selecting an interpolation method to estimate a frequency of the at least one tone using the three consecutive bin values.
