1. Apply LCC to rear channel speakers to get it running on 4.0 channel systems. The rear channel speaker distance can be digitally positioned with an integrated millisecond delay control, which allows a user’s rear channels to be digitally placed at various perceived physical distances if there is no way to move rear speakers back physically (the speed of sound is roughly 1100 ft./second (depending on temperature and elevation); so, for example, if a user has a rear head to speaker (H2S) distance of 2’0", when the frontal H2S is 6’0", it may be desirable to delay the rear speakers by say 5’0" to avoid erroneous localization to the rear). The system calculates this optimizing distance, e.g., 5'0"/1100 = ~.0045 seconds or ~4.5 milliseconds, and thus allows the user to experience the rear channel speakers optimally as if they were at ~7’0" and not where they are physically located at 2’0". Could also use a 4.0 Bluetooth speaker setup for your VR system. Better than headphones, as you now use your own natural HRTFs in a free field space. Also, headphones cause fatigue and contribute to disorientation. If that is of interest to you, taking it one step further with head tracking would require additional access to LCC's parameters.

2. Rearrange car speakers (see white papers for guidance on placement requirements) and apply LCC to the driver and each passenger. Not only a great idea from an entertainment point of view but also as an auditory safety function as well.
