Spectral Noise Playground

Hand-drive the spectral_noise synthesizer: the texture is random noise shaped to exactly the spectrum you set below. Hover any label for an explanation. Both outputs are copy-pastable Geoscript.

spectral peaks

No peaks. The band grid alone makes fully stochastic textures; add a peak to introduce an oriented wave (fabric ribs, wood grain).
