JavaScript => public var cutoffFrequency: float;
C# => public float cutoffFrequency;

Description 描述

Lowpass cutoff frequency in hz. 10.0 to 22000.0. Default = 5000.0.

低通截止频率在10.0～22000.0hz。默认=5000.0。

截止频率（cutoffFrequency），在滤波器中，以CutoffFrequency决定要去掉哪个频率范围的声音。

Note that setting this value will reset any custom cutoff curve set for this AudioLowPassFilter.

注意，设置这个值将重置任意用于该AudioLowPassFilter的自定义截止曲线设置。

JavaScript:

	// Moves the cuttoutFrequency from 10 to 22000 following a Sinus function
	// Attach this to an audio source with a LowPassFilter to listen it working.
 
	@script RequireComponent(AudioSource)
	@script RequireComponent(AudioLowPassFilter)
 
	function Update() {
		GetComponent.<AudioLowPassFilter>().cutoffFrequency = (Mathf.Sin(Time.time)*11010 + 11000);
	}

C#:

using UnityEngine;
using System.Collections;
 
[RequireComponent(typeof(AudioSource))]
[RequireComponent(typeof(AudioLowPassFilter))]
public class ExampleClass : MonoBehaviour {
    void Update() {
        GetComponent<AudioLowPassFilter>().cutoffFrequency = Mathf.Sin(Time.time) * 11010 + 11000;
    }
}
