About
A three-band multiband compressor for dense, heavy mixes: two Linkwitz-Riley crossovers split the signal into Low, Mid and High bands, each with its own full-featured compressor, console-style mute/solo, and an optional brickwall limiter on the high band.
Why the name?
A triptych is a three-panel altarpiece: three images, hinged into one work. Triptych splits your signal into three bands — low, mid, high — compresses each on its own panel, and hinges them back into one picture.
Features
- Two crossovers — Low/Mid (40 Hz–1 kHz) and Mid/High (400 Hz–12 kHz) with enforced band-order separation under automation
- Per-band compression — Threshold, Ratio (up to 20:1), Knee (v0.2.0), Attack, Release and Makeup for each of Low / Mid / High
- Per-band Mute/Solo — console semantics; compressors keep running under solo, so no re-attack pop on unmute
- High-band limiter — optional brickwall stage after the High band's compressor
- Zero added latency — minimum-phase crossovers and envelopes, no lookahead
- Output — master trim, ±24 dB
- Factory presets & preset management — browse/save/import/export via the in-plugin preset bar
- Full state save/recall
