METHOD AND APPARATUS FOR CONVERTING LEFT AND RIGHT CHANNEL INPUT SIGNALS OF TWO CHANNEL STEREO FORMAT INTO LEFT AND RIGHT CHANNEL OUTPUT SIGNALS

摘要

PROBLEM TO BE SOLVED: To obtain a method for converting a two channel stereo format signal into a signal suitable for reproducing by means of a headphone.;SOLUTION: A left direct path (Ld) signal and a left crosstalk path (Lx) signal are formed from a left input signal (Lin), and a right direct path (Rd) signal and a right crosstalk path (Rx) signal are formed from a right input signal (Rin). A left output signal (Lout) is formed by synthesizing the left direct path (Ld) signal and the right crosstalk path (Rx) signal, and a right output signal (Rout) is formed by synthesizing the right direct path (Rd) signal and the left crosstalk path (Lx) signal. Both direct path signals are formed using filtering (1, 3) associated with the first frequency dependent gain (Gd) and the crosstalk path signals are formed using filtering (2, 4) associated with the second frequency dependent gain (Gx) and adding inter-ear time differences (5, 6).;COPYRIGHT: (C)2002,JPO
