AudioSource.spread

描述

设置 3D 立体声或多声道声音在扬声器空间中的扩散角（以度为单位）。

0 = 所有声道的音频都位于同一个扬声器位置，为“单声道”。360 = 所有子声道都位于与其根据 3D 位置应位于的扬声器位置相反的扬声器位置。默认值为 0。

using UnityEngine;

public class Example : MonoBehaviour
{
    // when any AudioSource goes trough this transform, it will set it as 'mono'
    // and will restore the value to 3D effect after exiting
    // Make sure the audio source has a collider.
    void OnTriggerEnter(Collider other)
    {
        AudioSource audio = other.GetComponent<AudioSource>();

        if (audio)
        {
            audio.spread = 0;
        }
    }

    void OnTriggerExit(Collider other)
    {
        AudioSource audio = other.GetComponent<AudioSource>();

        if (audio)
        {
            audio.spread = 360;
        }
    }
