Patent ID: 7889872

Claim:
A device for integrating sound effect processing and noise control comprising: a digital signal processor for performing reverberation and sound positioning processing to an input audio signal, said sound positioning processing including 3D sound effect processing of a head-related transfer function, said head-related transfer function being expressed by an interaural transfer function; a sound player comprising a loudspeaker and a sensor disposed in front of said loudspeaker, said sound player receiving and playing said audio signal and using said sensor to detect said audio signal with an external noise attached thereto; and a noise controller connected to said digital signal processor and said sound player, said noise controller generating an anti-noise signal according to said audio signal with said external noise attached thereto to eliminate interference of said external noise to said audio signal; wherein Wiener filter is used to obtain a realized structure of a lower-order finite impulse response filter of said interaural transfer function, and said realized structure is designed for the audible frequency range of humans, and ignores sound frequencies that are inaudible.
