Fourier transform

A Fourier transform is a mathematical procedure for determining the frequency components of a particular signal. In audio signals, this method shows what components of a signal are made up of high, medium, or low sounds, and the volume and amplitude of each sound. This is essential for reverse-engineering a complex sound-producing system like the human voice.

Fourier transformations are the keystone of both voice recognition, and, to a lesser extent, virtual voice creation.

Literary Role Play
?Muds are designed to move role playing onto computer networks. Yet they do not merely translocate, but transform role playing: the different environment, in which the players are also authors, and the text medium, which requires expressive language, can lead to a different type of role playing.?

This book, attempts to show in general terms, as well as in specifics, just what the continuously overlapping waves of disruptive technology, will do to transform he way the world learns. Whether or not educational institutions choose to try to keep up, business training has to adapt, if it is going to continue to succeed.

Creative non-fiction guru and seasoned immersion journalist Gutkind observes that just as computers changed the world in the 1990s, robots will transform technology in the near future. To find out who is behind the growing robotic surge, Gutkind spent six years observing life at Carnegie Mellon's Robotics Institute.

This book, by author and renowned VR expert Howard Rhinegold, was first published in 1991 ? nearly twenty years ago. All those years back, Rhinegold still managed to predict VR applications that are only just being realised today.
