VCA compressor model (dbx/SSL-bus class) — clean feed-forward, near-hard knee

import vca from '@audio/dynamics-vca'

Clean feed-forward peak-detecting compressor after dbx/SSL-bus VCA topology: precise dB-linear gain computation, near-hard 1 dB knee, fast 1 ms attack. The transparent workhorse of the family — same compressorGain curve as compressor, tuned for speed and neutrality rather than character.

vca(data, { threshold: -20, ratio: 4 })                 // batch
vca(data)                                                  // defaults

let write = vca({ threshold: -20, ratio: 4 })            // streaming
let out1 = write(block1)
let tail = write()                                         // flush

Use when: mix bus glue, precise transparent gain reduction without coloration.
Not for: vintage character — use opto or varimu.
