摘要:
A surround sound processor system includes an in-phase decoder circuit, an out-of-phase decoder circuit, and a plurality of audio amplifiers. In a wireless embodiment, the surround sound processor system also includes a plurality of FM transmitters and a plurality of FM receivers. A surround sound process system can take the stereo audio signal from a stereo VCR, a stereo receiver, a car stereo, or a stereo TV to produce a three dimensional sound field. A left audio signal and a right audio signal are input into an in-phase decoder, the in-phase audio signals are extracted from the left and right audio signals while the out-of-phase audio signals are canceled. The in-phase audio signals are sent to an audio amplifier and then to at least one center speaker. A left audio signal and a right audio signal are input into an out-of-phase decoder, the out-of-phase audio signals are extracted from the left and right audio signals while the in-phase audio signals are canceled. The out-of-phase audio signals are sent to an audio amplifier and then to at least one rear speaker. The wireless surround sound processor utilizes an FM transmission link as opposed to hard wiring.
