Multi-resolution image stacks beat pyramidal magnitude in a new audio test
johnowhitaker · x · 2026-07-22
A reply thread compares different representations for generated audio and images, saying that stacking images at multiple resolutions produced clearer structure than a pyramidal magnitude representation.
The author reports that the same idea looks promising on raw audio or spectrograms, but the pyramidal magnitude version seems strictly worse and even fades out. They are running more tests, suggesting the underlying hypothesis is that the prior works better for images than for audio, and that multi-resolution structure may be the more useful direction.
