@audio/effect-exciter

Exciter — psychoacoustic harmonic synthesis for presence/air

npm install @audio/effect-exciter

import exciter from '@audio/effect-exciter'

Aphex-style aural exciter. Extracts the high band via SVF highpass, runs it through tanh saturation to synthesize harmonics, then mixes the harmonic residue back into the dry signal. Adds perceived "air" and "presence" without EQ boost.

freq highpass cutoff Hz (default 3000) · drive saturation amount 0–1 (default 0.5, maps to 1–10× gain) · amount mix-in level 0–1 (default 0.5) · fs sample rate

import { exciter } from '@audio/effect'

let p = { freq: 4000, drive: 0.6, amount: 0.4, fs: 44100 }
for (let buf of stream) exciter(buf, p)

Use when: dull vocals, lifeless cymbals, mastering polish, restoring high-end after compression Not for: spectral shaping (use a shelf/EQ from @audio/filter) — exciter adds harmonics, not gain
