@audio/dynamics-fet

FET compressor model (1176 class) — 0.2 ms peak attack, high ratios, firm knee

npm install @audio/dynamics-fet

import fet from '@audio/dynamics-fet'

Very fast peak-detecting feed-forward compressor after the UREI 1176 topology (same soft-knee gain curve as @audio/dynamics-compressor, tuned to the 1176's character: sub-millisecond attack, firm 3 dB knee, high ratio). Character comes from speed, not coloration — no saturation modeling.

fet(data, { threshold: -18, ratio: 8 })                 // batch
fet(data)                                                 // defaults

let write = fet({ threshold: -18, ratio: 8 })            // streaming
let out1 = write(block1)
let tail = write()                                        // flush

| Param | Default | | |---|---|---| | threshold | -18 | dB | | ratio | 8 | — | | knee | 3 | dB (firm) | | attack | 0.2 | ms | | release | 120 | ms | | makeup | 0 | dB | | sampleRate | 44100 | Hz (alias fs) |

Use when: drums, bass, aggressive vocal — fast peak-catching character with an audible "grab". Not for: transparent leveling — use compressor or vca.

Part of @audio/dynamics — the dynamics family umbrella.
