I mean, lets say we have 4 signals with values: 1 2 4 8 threshold between 2 and 4 give for ex. this: 1 2 3 4 now i add both an divide by 2: 1 2 3.5 6 _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
