Early Reflection Locator — geometric first reflection calculator, trial free / $9 full

[Bear Cub Studio]

Hi,

I'd like to share a tool I developed: Early Reflection Locator.

Finding first reflection points with the mirror method typically requires two people — technically doable solo, but awkward and time-consuming. REW, while powerful, doesn't show reflection points geometrically either.
This tool fills that gap.

Enter your room dimensions, speaker positions, and listening position — it instantly calculates all first reflection points and plots them on a 2D floor plan using the mirror image (specular reflection) method.

The trial version is free and displays reflection paths on a floor plan. The full version ($9) adds coordinates (cm), delay times (ms), hover tooltips per reflection point, and a printable A4 report including SBIR dip frequency estimates (c/4d).

Scope: geometric acoustics only — no diffraction, no modal behavior. Designed as a planning aid for absorption panel placement, not a substitute for measurement.

Single HTML file. Fully offline. No dependencies.

Cheers!
