Origin (Reference Point)

X (L/R)

Y (Height)

Z (F/B)

Delays are measured from this point — typically the main PA (L/R hang or mono cluster).

Speakers

Groups

Assign speakers to a group — moving one moves the whole cluster together.

Listener Y

1st-order wall reflections

Computes coherent SPL on the listener plane at the chosen frequency. Hot spots = power alleys (constructive sum of bass cabs); cold spots = nulls/cancellation. Re-run after moving speakers or resizing the room.

How it works

Place a speaker relative to the origin. The app calculates its distance and the propagation time at the current air temperature. Use that time as the delay setting on the processor feeding that speaker, so its sound aligns with the reference PA at the listening position.
