I am writing a book about vibrating energies and sound is discussed thoroughly. Here is what I predict in the future of sound technology: There will be 3D sound, speaker and microphone technology will totally change in concept, voice recognition and production is in its infancy, new musical instruments, music beamed silently directly to the brain, sound behavioral management of organisms and our brains, sound in physics and medicine will have new discoveries, recording sound from other dimensions and possibly the past. To top it off I can see this coming sooner than we think: keyboards, switches, rotary and digital controls will become a thing of the past. Some day kids will ask their parents "what was the dial on a telephone for?" Why did they have switches on things, as voice recognition and synthesis will do away with having to press buttons, and even beyond that the sound recognition technology to control things will be surpassed with direct control from just thoughts from our brains. My god maybe we will end up just being brains on a pedestal or just pure thought energy?
