hmpf, i dont really understand what i found on wikipedia.. how can i adapt that pseudo code ( http://en.wikipedia.org/wiki/Low-pass_filter) so i can check for a specific frequency of a sample? that pseudocode looks not too complex, but what for example does that := means?? and is this thing representing the whole sound: real[0..n] x ?? thanks in advance, ello
