Three great project ideas for LCC:
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.
3. Get LCC into a https://www.hifiberry.com https://www.hifiberry.com and purify your home theater's sound system with the most effective spatial audio solution available.
- L2iL 6y agoBonus 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!

The rear channels are easier (integrate into headrests with level and delay controls). Rear passengers are even easier (integrate frontal stereo pairs into back of driver and back of front passenger seats). This design may one day make things a lot easier: https://ifworlddesignguide.com/entry/273938-bo-for-ford-mustang-mach-e https://ifworlddesignguide.com/entry/273938-bo-for-ford-must...
- L2iL 6y agoWe'd also love to see LCC integrated into every seat in a movie theater where each person gets their personal 4.0 LCC experience (integrated into each seat) and woofers and subs are located elsewhere (perhaps where they are already located in Dolby and IMAX theaters) and distributed for every patron. This is less of a personal project and more of a partnership.
