    audio signal processing and detect its frequency

    hi again i tried bandpass active filter , lm567 tone decoder and etc. but they didn't work well. i use fixed frequncies and i want to detect five constant freq.470hz , 610hz and etc do you know about goertzel algorithm can i use it for detecting freq in this case. thanks alot
