Cooper Bauck Corporation/Cooper Bauck Transaural
Duane H. Cooper and Jerry Bauck gave birth to the modern era of practical head-related stereophony after Manfred Schroeder's original work lay as a laboratory curiosity for many years. Since their early publications in this area the field has grown significantly.
"The Cooper Bauck companies create, license, and use audio recording and playback technology which makes possible the finest, most realistic recordings of music and other acoustic events, along with applications in multichannel playback on a reduced number of loudspeakers."
