Abstract:
1. Method of interpolating between two time consecutive balance values, a balance value being derived from a stereo audio signal or a multichannel audio signal having a first audio channel and a second audio channel, comprising: studying, by a processor, a mono audio signal derived from the first audio channel and the second audio channel to obtain information on beginnings or endings of sound events; in response to the information, calculating, by a calculator, an interpolated balance value between the two time consecutive balance values such that a first change in balance position by a first balance increment is performed during a time segment, in which the mono audio signal has a first energy, and that a second change in balance position by a second balance increment is performed during a time segment, in which the mono audio signal has a second energy, wherein the first change in balance position is greater than the second change in balance position, wherein the first energy is lower than the second energy, and wherein the first balance increment is larger than the second balance increment.
