Local Ray Tracing, an EASE feature, provides a way to take a quick look at the electro-acoustic performance at selected location around the room. Unlike Local Decay Times which used an omnidirectional sound source to emit rays into the room, Local Ray Tracing uses the room’s loudspeaker system.

It produces a Reflectogram that displays the arrival times and SPL levels of all the direct and reflected rays that strike the selected location(s). Projected RT Times, Intelligibility and Frequency Response displays are also available at the click of a button. It’s a quick way to look at the loudspeaker alignment in multi-loudspeaker systems and observe the early arrivals.
A typical Reflectogram created with 1000 rays per loudspeaker and up to 3rd order reflections appears below.
