Score: 6.8/10 (Innovation: 7, Technical: 8, Documentation: 8, Utility: 4)

HSL-Noise is a browser-based audio tool that maps the HSL color space onto noise profiles, letting users dial in a color to synthesize a specific band of noise using Gaussian spectra, velvet noise, and comb filtering. The engineering is impressive—custom AudioWorklet DSP, perceptually tuned saturation-to-bandwidth mapping, and a pure functional color-space library—but its audience is narrow, primarily appealing to audio hobbyists, DSP tinkerers, and generative-music enthusiasts.

Target audience: audio developers, DSP hobbyists, sound designers, generative music artists
