Control system of sound image localization
专利汇可以提供Control system of sound image localization专利检索，专利查询，专利分析的服务。并且PURPOSE:To enable directly sound image localization control with high accuracy by utilizing a digital control signal decided by a distance between localizations of right and left channels, a sound image position by using a center position of the localization as a reference and the number of bits. CONSTITUTION:A polyphonic synthesizer module (PSM)3 as a music generator and pan-pot circuits 4 and 5 are controlled by a control signal of a CPU2 based on an output of a keyboard 1. Consequently in accordance with a gain ratio corresponding to a position of an input key, music signals from the PSM3 are distributed to channels L and R by actions of the circuits 4 and 5, and added. The pan-pot circuits 4 and 5 are constituted in such a way that digital variable gain circuits for controlling variably voltage gains in accordance with the control signal are placed in both signal systems. Assuming that a distance between localizations of right and left channels is 2y and a sound image position using a center position between localizations as a reference is x, control signal data D to satisfy an expression I are used with respect to the number k of bits of data. The data D and complement data are given to the circuits 4 and 5, respectively. Thus a proper sound image localization control can be carried out.，下面是Control system of sound image localization专利的具体信息内容。
