You're probably talking about the artifacts of converting a low resolution spectrogram to audio.

  Can the spectrogram image be AI upscaled before transforming back to the time domain?
  • malka 4y ago
    Yes it exists: https://ccrma.stanford.edu/~juhan/super_spec.html https://ccrma.stanford.edu/~juhan/super_spec.html But the issue is not that the spectrogram is low quality. The issue is that the spectrogram only contains the amplitude information. You also need phase information for generating audio from the spectogram

      Interesting, can't you quantize and snap to a phase that makes sense to create the most musical resonance?

    What happens if you run one of the spectrogram pictures through an upscaler for images like ESRGAN ?
