Optimisation tips

Use staged optimisation

Don’t chase 95–99% pass rate on the first run.

A good pattern:

1. Coarse grid (larger step) + moderate threshold → find a strong basin
2. Finer grid (smaller step) → refine
3. Tighten threshold gradually while reducing step size

Watch what “improving” actually means

• Pass rate can rise while tail failures (catastrophic errors) remain.
• Track P95 and Max alongside pass rate.

When you get stuck

• Increase probes per mic a little
• Allow occasional shake/reset
• Try small manual mic adjustments to break symmetry
• Re-run WAH before re-optimising after major parameter changes

Practical geometry advice

• Avoid near-coplanar layouts
• Ensure diversity in 3D baselines (not all mics on one ring)
• Keep minimum spacing realistic for your mount/manufacturing tolerances
