Claim 12:
13. A non-transitory digital storage medium having a computer program stored thereon to perform the method for estimating an inter-channel time difference between a first channel signal and a second channel signal, comprising:
calculating a cross-correlation spectrum for a time block from the first channel signal in the time block and the second channel signal in the time block;
estimating a spectral characteristic of a spectrum of the first channel signal for the time block or the second channel signal for the time block;
smoothing the cross-correlation spectrum over time using the spectral characteristic to acquire a smoothed cross-correlation spectrum; and
processing the smoothed cross-correlation spectrum to acquire the inter-channel time difference,
when said computer program is run by a computer.
