A method for adaptive and surround sound systems

The present invention discloses a method and system for adaptive surround sound, the method comprising: using the target recognition user specified location in the room and the room identification, a control technique using a focus control camera focus image acquisition target identified, and records the focusing parameter; of the image and a parameter calculating out of the room based on the position information of the camera and the user's position relative to the camera with respect; based on the calculated positional information of the room and the user calculated can be a user within the room achieve beam at a position surrounding sound; sound beams according to the calculated, to obtain the parameters of the filter bank, the filter bank and adjust the speaker array based on the parameter; rear audio signals through the filter bank adjusted filtered parameter, playback by a speaker array, a user at a location within said room forming the surround. Thus it can avoid an additional acoustic calibration process and the calibration device, easy to use and is not limited to the user's location.
