Bonus project idea: Get LCC to work on horizontal speaker array sound emitters, e.g., soundbars with multiple speakers for each channel. You may need to apply LCC to each driver and adjust LCC parameters accordingly. Another variant is to build your own horizontal speaker array sound emitter that is steerable, e.g., use computer vision to track many heads in a room and send a L/R LCC image to each listener using beam forming speakers. Multiple sweet spots!
