ABSTRACT:
A method and apparatus for locating the user of a computer system and adjusting the sound from the system speakers. The computer system includes a computer, two speakers, a microphone, a signal processor, and an audio processor. The speakers emit a sound which is reflected from the user and other objects in the vicinity of the system. The invention includes an algorithm for determining which of the reflected sounds had been reflected from the user of the computer system. The character of the sound emitted by the computer system is then adjusted to enhance the sound effects at the location of the user.
