A friend and I have to make a system of filters (low pass, band pass and high pass) for applications in audio. The idea is filter a song and depending of the frequency make some effects with lights through, so we need to have the 3 filters together in the processing and send the info to the arduino for make the effects. We used the filters of the minim library but we can't utilise 2 or more filters together, for 1 it's no problem but that's not helpfull for us. We thought create a function with the 3 filters inside but we don't know how and we don't know if that it's going to work either.
I must say. the first idea was to make the filters in the arduino but we couldn't. So, if someone can help us either for make it work the 3 filters at the same time with processing or a way to do that inside the arduino.
Thank you very much, and sorry if my english it's a little bit weird sometimes XD
Bye.
