Hi, I trace freeamp code , and found something strange in msis.c void msis_init_MPEG2(MPEG *m){ ..................... /* illegal is_pos used to do ms processing */ if (ms_mode == 0) { /* ms_mode = 0 */ lr[intensity_scale][ms_mode][k][0] = 1.0f; lr[intensity_scale][ms_mode][k][1] = 0.0f; } Is anyone can tell me why in this situation (Intensity Stereo On ,ms_mode =0, and illegal intensity position) lr[][][0]=0 and lr[ ] [ ] [1]=1?? Thanks a lot ! Sincerely , Judy 29.March.2001 _______________________________________________ [EMAIL PROTECTED] http://www.freeamp.org/mailman/listinfo/freeamp-dev
