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 18):
A system, comprising:\n an encoder for encoding a magnitude spectrogram of an audio signal, and a decoder being an apparatus according to one  claim 1 , for decoding the audio signal, wherein the decoder is 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, wherein the decoder is 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, and wherein the decoder is configured to decode the audio signal using the magnitude spectrogram of the audio signal and using the phase values for the plurality of time-frequency bins.
