Can the spectrogram image be AI upscaled before transforming back to the time domain?
- malka 4y agoYes 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
- mcbuilder 4y agoInteresting, can't you quantize and snap to a phase that makes sense to create the most musical resonance?
- waltbosz 4y agoWhat happens if you run one of the spectrogram pictures through an upscaler for images like ESRGAN ?
