These super clear audio files are called holophony (holophonic sound recordings) and are designed to be listened to with headphones for the best effect. They have been recorded with a dummy head that has two microphones, one in each ear. The shape of the head and ears are designed to be similar to a human head to most closely replicate real human hearing. It’s pretty incredible.
Grab your headphones and have a listen. While the content itself isn’t that engaging, the sound effects will probably have you listening a second time.
