InverseSpectrogram

InverseSpectrogram[data] reconstructs the signal from the magnitude spectrogram data.

• InverseSpectrogram[img] reconstructs the signal, assuming that the image img is the magnitude spectrogram.
• InverseSpectrogram[input, n] assumes the spectrogram data was computed with partitions of length n.
• InverseSpectrogram[input, n, d] assumes partitions with offset d.
• InverseSpectrogram[input, n, d, wfun] assumes a smoothing window wfun was applied to each partition.

Examples

audio = ExampleData[{"Audio", "Apollo11SmallStep"}];
spec = Spectrogram[audio];
InverseSpectrogram[spec]
