A helps you understand spatial audio. Start with the Web Audio API code above, try the Virtual Barbershop on YouTube, and tweak position/distance parameters. Once you hear a sound orbiting your head, you’ve grasped the core concept.
The biggest problem with universal 3D sound examples is that HRTF is unique. A dummy head has average ears. Your ears are different. That is why some people say "I don't hear the 3D effect." 3d sound example
The goal is to replicate the way human ears actually perceive sound in the real world. In reality, your brain calculates the location of a sound source based on minute differences in timing and volume between your left and right ears, as well as how the sound bounces off the folds of your outer ear (the pinna). A utilizes algorithms called Head-Related Transfer Functions (HRTFs) to artificially recreate these cues. A helps you understand spatial audio
