MTB: Motion-Tracked Binaural Sound Capture and Reproduction

Full Description

A radically new method to improve the realism of sound with all its spatial characteristics has been developed by researchers at the University of California, Davis. This invention has a broad range of applications for either live or recorded sound. This new technology accounts for dynamic effects caused by the motion of a listener. In remote listening of live sounds, as well as in listening to recordings, MTB provides an unsurpassed sense of "being there." Until now, this sense of complete immersion in the environment was not possible. The technology overcomes major limitations of existing spatial sound technologies and opens new opportunities for a variety of applications with a mass-market potential.

Features/Benefits

• MTB brings the power of dynamic cues to the headphone reproduction of recordings made using other technologies
• MTB efficiently encodes the binaural spatial audio information and provides for the dynamic effects of head motion for any number of listeners simultaneously
• MTB provides a "universal format" for reproducing spatial sound from any source, including completely computer-generated sounds
• MTB requires no customization to the listener
