Quench splits the signal with a Linkwitz-Riley crossover and lets the sub pass unclipped. The top is clipped symmetrically at the ceiling minus the sub's held peak, so it does not pump at the sub's rate and the sum stays under the ceiling. What the clip removes is high-passed at the split, so its products stay out of the low band. Two correction passes and an oversampled hard clip hold the ceiling; a safety clip catches the downsampler's ringing. - Controls: Drive, Ceiling, Split, Hold, Soft, Bypass. - Listen to Quench, a plain clipper at the same settings, or the delta. - Editor meter compares how much the low band changed for Quench and for a plain clip, with a scope of the output, the sub and the top's room. - Measured: sub level +0.04 dB against -2.2 dB for a plain clip, low-band products -35 dB against -16 dB, at 0.5-1.2 dB less RMS. - Registered in the catalog, workflows, editor-check, README, chain and development docs, and the website copy.

Quench changelog
Unreleased (0.1.0)
- Introduce Quench, a clipper that clips the top and lets the sub pass clean.
- A Linkwitz–Riley split at Split (40–300 Hz). The top is clipped at the ceiling minus the sub's held peak; Hold sets how long that peak holds.
- What the clip removes is high-passed at Split, so its products stay out of the low band. Two correction passes and an oversampled hard clip hold the ceiling; a safety clip catches the downsampler's ringing.
- Drive, Ceiling, Soft (knee of the top's clip), Bypass.
- Listen to Quench, a Plain clipper at the same settings, or the Delta that Quench takes away. Not saved.
- Editor: how much the low band changed for Quench and for a plain clip, how far the top is clipped, the sub's peak and the room it leaves, and a scope.
- 4× oversampling; 37 samples of latency.
