search for: preecho_thresh

Hi all, Q1: The source defined this structure in the psy.h file: typedef struct{ int eighth_octave_lines; float preecho_thresh[4]; float postecho_thresh[4]; float preecho_minenergy; float ampmax_att_per_sec; int delaycache; } vorbis_info_psy_global; However, the file psytune.c makes this declaration: tatic vorbis_info_psy_global _psy_set0G={ 0, /* decaydBpms */ 8, /* lines per eighth o...

...e have data. 3. Search forwards in the filtered data from the minimal starting point j for a short block until the searchpoint argument: (a) Does the power in a [small] envelope at j change from the preceding envelope-sized block to the envelope-sized block at j by more than vd.vi->preecho_thresh? If so, impose a short block (well I suppose it could be the largest block with approx. a 3/4 mark at that point, but vorbis only has two blocksizes max, so the choice is easy. Return 0 if the power variation in some channel is too big. (b) increment j by half the smallest blocks...
