Spectral rolloff — frequency below which \`p\` of total spectral energy lies (default 85%).

Tape saturation — tanh transfer + playback HF rolloff (simplified machine model)

Spectral features — umbrella for @audio/spectral-* atoms (centroid, spread, flatness, rolloff, flux, slope, crest, zcr)

No description provided.
