TruPan is a panning tool.
The main drawback of an intensity-based pan-pot is that you must be at the optimum listening position to perceive the intended sound image. Any movement of the listener destabilizes the soundscape. Truality Panning creates a more stable image and a sense of aural depth. There is always sound in both channels (appropriately conditioned), even when panning to the extremes.
TruPan is uses a combination of filtering (head shadow effect), delay (precedence – Haas effect), and level manipulation (Intensity variation) and various techniques to minimize phase (Mono compatibility) problems.
