people coments on listening a stero recording in the 21st century

Binaural isn't used much simply because it only really works with headphones.

It's created using 2 microphones placed as they would be if they were your ears. Sometimes a fake head is used and they put the mics either side. The effect is that you're listening to the room not just the music.

Like I said it's not widley used because if you listen to a binaural recording through speakers the effect just doesn't work. Which is why we have surround sound systems now.

Radio is mixed, it goes through all sorts of sound processing before it is transmitted. Again, binaural won't really work over FM radio because the signal is heavily compressed before being transmitted (this sort of levels out the sound)
