Hi i am working on an instrument that triggers a sound when the brightest pixel reaches certain area, my problem is that every time ths happens processing triggers the audio several times per second so you can´t even listen to the full sound. I would love to get jus one trigger per zone every 2 or 3 seconds or when the sound finishes playing.
I am not very experienced programming so any help would be grate. thanks.
To test it you may need an audio file called notes 1.wav notes 2.wav , etc...
thanks again!!!
