Abstract:
An apparatus for phase reconstruction from a magnitude spectrogram of an audio signal is provided. The apparatus includes a frequency change determiner being configured to determine a change of a frequency for each time-frequency bin of a plurality of time-frequency bins of the magnitude spectrogram of the audio signal depending on the magnitude spectrogram of the audio signal, and a phase reconstructor being configured to generate phase values for the plurality of time-frequency bins depending on the changes of the frequencies determined for the plurality of the time-frequency bins.

Claim (Index 14):
The apparatus according to  claim 13 ,\n wherein the phase reconstructor is configured to determine the phase reconstruction mode for each time-frequency bin of the plurality of time-frequency bins so that the phase reconstruction mode indicates the first mode, if the measure of anisotropy for said time-frequency bin is greater than a lower threshold value, and so that the phase reconstruction mode indicates the second mode, if the measure of anisotropy for said time-frequency bin is smaller than or equal to the lower threshold value, or wherein the phase reconstructor is configured to determine the phase reconstruction mode for each time-frequency bin of the plurality of time-frequency bins so that the phase reconstruction mode indicates the first mode, if the measure of anisotropy for said time-frequency bin is greater than or equal to the lower threshold value, and so that the phase reconstruction mode indicates the second mode, if the measure of anisotropy for said time-frequency bin is smaller than the lower threshold value.
