Generate Sound from Image Using Inverse Spectrogram

Construct an audio signal from an image, assuming the image to be the power spectrogram of the original signal.

Use InverseSpectrogram to calculate the approximate inversion of the spectrogram operation. This assumes that the input image is the magnitude spectrogram and iteratively tries to reconstruct the phase.

Visualize the Spectrogram of the resulting signal.

Create an audio object from a black-and-white portrait.

The large black areas in the image are transformed into silence. Visualize the spectrogram of the computed signal.
