Found this [8D Audio song](https://youtu.be/O5ooPGEiXkg) on YouTube and listened to it with my AirPod pros. What alterations are done to the audio that makes it so much more dimensional?

At the end of the day, you have only two ears.
The way you detect speaker locations and room size are from time delays of the sound to each ear and the sounds of echos. Both of these can be simulated in software to make it sound like someone is right behind you or 20 feet to your front right. Your brain is what interprets where it thinks the sound is coming from.
You only need two speakers/headphones.
If you played every frequency in a big room and used a microphone to record you would notice specific frequencies are louder or quieter or echo more. Using this data you can create a filter to put on music that goes through the frequencies and changes them to how it sounded in the big room. If you listen close you will notice the echo.
Along with the other responses, it doesn’t necessarily require post processing. Live performances can be recorded with binaural microphones that mimic the position, and sometimes even the shape, of human ears, so when played back it sounds much like you were actually there.
All of these effects work best with headphones because they provide the best control and separation of what sound goes to each ear. It’s possible with two speakers, but there’s more inherent mixing of the audio from each channel and you generally have to be in the “sweet spot” for it to work well at all.
Thanks everyone! I’ve heard other 8D audio tracks before but never one this dynamic!
