If you have ever moved a speaker a few centimetres and then listened to the same track six times, you already know why the details matter. These pages explain what DecayCore measures, what it tries to correct, and where it leaves well alone. Start with the concepts; the equations are here for the evening that was supposed to involve just one album.

Concepts

Why DecayCore Works

Why some peaks are worth cutting, some dips are best left alone, and your amplifier deserves a little breathing room.

DecayCore vs conventional EQ

What looking at timing and decay adds to the familiar job of adjusting frequency response.

Temporal Decay Control

What to do when a bass note hangs around after the player has moved on.

Adaptive Target

How the measurements from both speakers guide small changes to the bass target.

Filter types

When to use Asymmetric, Minimum Phase, Mixed Phase, or Linear Phase correction.

Workflows and focused features

AUTO, BASIC, and ADVANCED

Let Automatic find a starting point, use Basic for manual adjustment, or get into the details with Advanced.

Hybrid IIR + FIR

How IIR handles narrow bass resonances while FIR takes care of broader correction.

Technical reference

DSP pipeline

The processing stages, control roles, phase strategies, synthesis, export, and cache contract.

Mathematical model

Equations for alignment, confidence, magnitude shaping, phase construction, TDC, and FIR synthesis.

DSP guards

The limits that keep correction strength, timing, and the underlying calculations under control.

Stability and reproducibility

Requirements for comparable runs and the diagnostics used to explain differences.
