Sigberg Audio PEQ Assistant
Enter measured bass response values. The tool groups broad peak regions, suggests conservative PEQ cuts, estimates the corrected response, flags deep dips, and avoids aggressive ruler-flat correction. Use Save data to keep your inputs for next time.
Settings
Hover over any field for a short explanation. Recommended workflow: use 1–3 filters, re-measure, then listen. Adjacent peaks are grouped only when there is no clear valley between them. Dips deeper than about 5 dB are normally better addressed with placement, phase, crossover or delay rather than PEQ boost. Suggested cuts smaller than 1 dB are ignored.
