“Even if you're on the right track, you'll get run over if you just sit there.”
Will Rogers
It's said that when an early motion picture was first shown to the public, women fainted and men ducked from an approaching train. The director made a bold new decision that would alter the course of filmmaking for the next century. Instead of just placing the camera in front of all the action like an audience watching a stage, the director moved the camera to a new position - within the action - to create perspective. There were more changes on the way. About a hundred years ago, the first color and 3D films were being created. In an Avant Garde era when artists were distorting reality, most filmmakers were trying to recreate reality and immerse the viewers into it.
Realistic sound is no exception. In fact, stereo sound was first demonstrated in 1881, and multiple speaker playback in the early 1930's. These early attempts at locating sounds for the listener were impractical though, and required expensive and ungainly equipment. By the late 1950's, consumers could finally experience stereo with LPs and tapes. But until home theater systems became popular, most had to go to a place like a theater or theme park to experience anything beyond stereo sound.
Since digital audio and video have pretty much taken over the world, we've seen a rapid growth of new technologies. Virtual reality is one of those, like the Oculus Rift, a VR headset for the masses. This is a visual VR device. But what's lacking is auditory VR.
Enter the researchers at Microsoft. They've created a way to fool a listener into thinking sounds are coming from a specific location using ordinary headphones. To make it work, the listener's head and shoulders are scanned into 3D software, which then builds a custom filter. Add motion sensors and a camera to track the listener's position, and the fun begins. Sounds can seem to be coming from objects or areas in a room. Imagine making that stuffed Teddy bear in the corner of your child's room actually talk. That model hot rod on the shelf could rev its engine. The uses seem endless.
It's obvious that this new device will be used as a companion to a visual VR headset. But there could be many more uses. Theme park attractions could be revolutionized by creating more realistic environments while eliminating costly sound systems. The movie industry could enhance the viewer's experience. Music artists could create the ultimate mix, with that lead guitarist standing next to the coffee table.
I think the largest user of this technology will be the advertising industry. Imagine walking down the street with your headphones listening to some music when a voice from your left whispers, "Pssst! Hey buddy, wanna buy a watch?" You turn and see the sparkling Bulova timepiece in the window of the jewelry store.

The new generation is discovering what the old generation stopped loving - LPs. LP sales are the highs they’ve been in 22 years. Records aren’t just for hipsters anymore, everyone, including the older generation that gave them up, are groovin’ to them.

How would you describe a sound to someone without using descriptors that are unique to sound, like: loud, bassy, shrill, whining, atonal, or noisy?
Not a problem, because we most often describe a sonic experience with words related to our other senses: sharp, warm, angular, raspy, piercing, even, warbling, soft, smooth, or flat.
