FOA Mic Enclosure

thingiverse

This First-Order Ambisonics Microphone Enclosure Can Be Used To Create Immersive Sound Experiences That Engage People On A Deep Level. Many Individuals Have Been Introduced To Virtual Reality, But They Often Remain Unaware Of The Extensive Research Dedicated To Developing High-Quality VR Sound. Ambisonics Is An Advanced Technology That Has Been Resurfacing With The Rapid Growth Of VR. After Conducting Extensive Trials And Errors, My Friend Yigal Kamel (A Brilliant Mind) Successfully Helped Me Develop This Enclosure, Which We Are Currently Using As Our First Prototype. We Also Created Custom PCBs And Soldered Essential Circuits To Get The Entire System Working In Harmony. The Audio Was Decoded Utilizing Omnitone. For An Easy-To-Deploy FOA Decoding Solution, I Highly Recommend Checking Out The ForgeJS Library. The Encoding Process Is Extremely Straightforward (Written In Matlab, But You Can Also Use Octave): W = FLU + FRD + BLD + BRU <---omni X = FLU + FRD - BLD - BRU <---front/back Y = FLU - FRD + BLD - BRU <---left/right Z = FLU - FRD - BLD + BRU <---up/down FLU = front left up FRD = front right down BLD = back left down BRU = back right up The Front Of The Mic Is Positioned Between Two Capsules, One Pointing Up And Left, And The Other Pointing Right And Down. This Page Will Guide You Through The Steps Necessary To Build Your Own First-Order Ambisonics Microphone Enclosure. I Have Also Added Three New Designs With Closed Backs, Each In A Different Size.
