@audio/filter-spectral-tilt [](https://www.npmjs.com/package/@audio/filter-spectral-tilt) [](https://github.com/krishnized/license)\n\nSpectral tilt filter: apply a constant dB/octave slope to the spectrum\n\n```\nnpm install @audio/filter-spectral-tilt\n```\n\n```js\nimport spectralTilt from '@audio/filter-spectral-tilt'\n```\n\nApplies a constant dB/octave slope — tilts the entire spectrum.\n\n**Model**: cascade of 8 octave-spaced first-order shelving sections approximating a fractional power-law spectrum $S(f) \\propto f^\\alpha$; positive slope boosts highs, negative slope cuts them
\n**slope**: $\\alpha = -3\\,\\text{dB/oct}$ gives pink noise character; $-6\\,\\text{dB/oct}$ gives brownian/red noise
\n**Accuracy**: measured slope tracks the requested dB/oct to within ~20% (inherent to the 8-stage shelving cascade) — e.g. `slope: +3` measures ≈+2.4 dB/oct, `slope: -6` measures ≈-4.9 dB/oct\n\n```js\nspectralTilt(buffer, { slope: -3, fs: 44100 }) // −3 dB/oct: pink noise character\nspectralTilt(buffer, { slope: +3, fs: 44100 }) // +3 dB/oct: pre-emphasis for coding\n```\n\n| Param | Default | |\n|---|---|---|\n| `slope` | `0` | dB/octave; `0` is a no-op (returns `data` unmodified) |\n| `fs` | `44100` | sample rate, Hz |\n\nPass the same `params` object on every call to persist the 8-section cascade state across blocks.\n\n**Use when:** matching microphone/speaker frequency responses, spectral coloring, noise synthesis.\n\n---\n\nPart of [@audio/filter](https://github.com/audiojs/filter) — the filter family umbrella.
