public class Example : MonoBehaviour
{
    // Moves the cuttoutFrequency from 10 to 22000 following a Sinus function
    // Attach this to an audio source with a LowPassFilter to listen to it working.

    void Update()
    {
        GetComponent<AudioLowPassFilter>().cutoffFrequency = (Mathf.Sin(Time.time) * 11010 + 11000);
