The Resonator-Test.awd file shows the use of the Feedback Delay module as a resonator. There are two delay lines panned hard left and hard right listening to the stereo input signal. The delay time settings and modulation levels are individually settable. A percussive drum beat WAV file is included for testing to highlight the action of the resonator.

As you can see and hear, the processed signal has enhanced the signal energy at frequencies whose periods correspond to integer divisions of the delay time. This is shown in Figure 8 by the strengthened horizontal lines indicating the amount of energy. The frequencies are evenly spaced on a linear scale. The spacing for the left and right channels is different as the delay times were different when the recording was made.
