2.1.10. Tolerance mode

---

The tolerance mode combo-box allows you to choose how gain is applied within the target tolerance zone.

• Dead Zone leaves signals already inside the target tolerance zone unchanged and clamps out-of-range signals to the nearest tolerance edge.
• LRA Scaling learns a source loudness window over the current history length window, then maps the source’s relative position within that learned window directly into the target tolerance band. Source below or above the learned window clamps to the lower or upper tolerance edge.
• Adaptive softly centers toward target loudness. Inside the tolerance zone, the centering pull is scaled by program stability (lower learned LRA = more centering). Outside the zone, it transitions from edge clamping toward center capture.

Adaptive and LRA Scaling both learn from the rolling history length window.
