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 6):
The apparatus according to  claim 5 ,\n wherein the apparatus frequency change determiner is configured to determine the change of the frequency for each time-frequency bin of the plurality of time-frequency bins depending on the formula R \ue8a0 ( b , k ) = f s 2 HN \u00b7 tan \ue8a0 ( \u03b1 \ue89e ( b , k ) ) wherein (b, k) indicates a time-frequency bin of the plurality of time-frequency bins, wherein R(b, k) indicates the change of the frequency for said time-frequency bin, wherein b indicates time, wherein k indicates frequency, wherein f s  indicates the sampling frequency of the audio signal, wherein N indicates the length of the analysis window, wherein H indicates the hop size of the analysis window, and wherein \u03b1(b, k) indicates the angle for said time-frequency bin, wherein the angle \u03b1(b, k) depends on the magnitude spectrogram.
