Introduction

Room correction can improve some problems and cannot repair every acoustic limitation.

Features and software

Correct One lets users cap the correction frequency, edit target tilt, and inspect every generated filter.

Measurements

Before and after room response · Demonstration room average · nine microphone positions
Prototype demonstration data — not a real product measurement.

Limitations

Poor microphone placement still produces poor filters, and no software can remove late reflections from an untreated room.

Conclusion

The fictional software earns credit by exposing trade-offs rather than hiding them behind a single optimisation button.
