專利摘要(中)
一種立體聲場錄音以及重建的方法，為將一麥克風陣列設置於一立體聲場，對該立體聲場中之聲源的方位進行追蹤，分離出對應的一聲源訊號。並利用該聲源訊號，於所欲重建該立體聲場的一域區內，設置複數個該控制點，利用該控制點，建立該聲源訊號、該立體聲場與一重建聲場、一重建聲源訊號之間的一關係式，進而求解該關係式而得到該重建聲源訊號，將該重建聲源訊號輸入佈置於該域區外的一喇叭陣列，而於該區域建立該重建聲場。據此，本發明於錄音時詳實記錄該聲源訊號，不需進行額外轉換程序，而回放時具有不容易失真以及甜區較大的優點。 A method for recording and reproduction of a stereophonic sound field, which includes the steps of disposing a microphone array in the stereophonic sound field, tracking directions of a plurality of sound sources in the stereophonic sound field so as to obtain a plurality of corresponding sound signals separated from the sound sources, setting a plurality of control points within an area of the stereophonic sound field for reproduction, establishing a relation between the sound signals, the stereophonic sound field, a reproduction sound field and a reproduction sound signal based on the control points so as to obtain the reproduction sound signal from the relation, and then input the reproduction sound signal into a speaker array deposed outside the area to reproduce the stereophonic sound field within the area. Accordingly, the method of the present invention could record the sound signals accurately and do not need additional conversion process. Moreover, the method has the advantage of less distorted and a larger sweet area during the reproduction.
