The age-old question for people recording sound: how do I make the audio sound like the listener is in the same room as the sounds? How do I make it convincing? Well, one answer is to finely adjust the audio. The other? Make a microphone shaped exactly like a human ear.
This might make the microphone look odd, but because the microphone is shaped like an ear, it captures sound exactly like an ear would, replicating the sounds exactly as we would hear it. The result is binaural recording: a huge breakthrough in the art of audio.
Headphones strongly recommended.
And in case you are as curious about that pineapple video as I was, here it is. Oh. my. goodness.
