This spreadsheet is the Swiss Army knife for subwoofer configurations. It helps you design, in real-time, cardioid configurations like end-fire and gradient. Horizontal arrays such as physical arcs and straight delay‑tapered arrays.
You can use up to 12 speakers with omnidirectional, cardioid, and super-cardioid speaker patterns. Apply low- and high‑pass filters. Look at absolute and relative arrival times.
It displays frequency and phase responses for up to 7 microphones, and shows you SPL, polar, and beamwidth plots. The comprehensive info‑panel will assist you in making design decisions, and nearly everything can be normalized in order to study relative differences.
As of version 1.4 results can be exported into Meyer Sound's MAPP XT™ for increased precision.
The exhaustive 71‑page manual covers all features and contains several tutorials.
