Also of note is the Wide Pan algorithm working in the background to only model the reflections that actually hit the listening position. This certainly makes some very interesting effects possible. Settings for the loss of high frequencies and their transition further refine the room model. Spatial Pan uses a perfect rectangular shape as its baseline but lets you modify it with width and depth parameters for the left, right, and back walls. Given the circumstances, the nature of the room also plays a role. To really make a point, the plug-in uses a graphical interface to let you place instruments and tracks on the virtual stage, and immediately hear the difference.

In other words, Spatial Pan includes the relationship between position and early reflections in the equation – in particular, the distance between the sound source and the listening position, and the resulting differences in early reflections volume and running time. Har-Bal’s solution is to create early reflections at contextually appropriate levels to imply room geometry.
