Technical Examples
- Apparatus for simulating sound properties of audio equipment not physically present in a simulated environment not physically present includes a source of binaurally encoded audio signals processed for loudspeaker reproduction characterizing audio equipment not physically present in a simulated environment not physically present. There are left and right electroacoustical transducers. A head locator is constructed and arranged to locate a listener's head in a predetermined position between and a predetermined distance from the left and right electroacoustical transducers so that the electroacoustical transducers are forward of the listener's head. Amplifying apparatus couples the source to the electroacoustical transducers. A selector operable by a listener with head substantially at the position is constructed and arranged to select the audio reproduced by the electroacoustical transducers to furnish that listener with a sound simulation of selected audio equipment not physically present in a selected simulated environment not physically present.
