DecayCore is designed as a conservative measurement and FIR-correction system. Its engineering documentation separates acoustic intent, numerical safeguards, operating policy, and measured evidence so that correction choices remain inspectable.
Start with the design rationale
Why DecayCore Works
A practical overview of measurement alignment, confidence-weighted correction, phase safety, decay control, and headroom.
Academic DSP Rationale
The mathematical model and the implemented sequence from time-of-flight removal through FIR synthesis.
Safety and reproducibility
DSP Guards Reference
Principled acoustic guards, technical numerical guards, dependency clusters, and operational triggers.
Stability and Reproducibility
Deterministic processing, bounded correction, input robustness, comparable evaluation, and run auditing.
Modes and room-aware behavior
AUTO, BASIC, and ADVANCED
How operating modes change search behavior, exposed controls, and conservative defaults.
Temporal Decay Control
Why low-frequency problems are evaluated in time as well as amplitude.
Adaptive Target
Room-aware target synthesis and its measurement-metadata requirements.
Evidence and advanced workflows
Measured performance case study
Methodology, limitations, source REW data, response, group-delay, waterfall, and full report.
Hybrid IIR + FIR correction
An optional workflow for narrow low-frequency cuts before bounded FIR synthesis.
The user-facing workflow remains in the User Manual. These engineering documents explain why the controls and defaults behave as they do.
