Unity获取麦克风音量（实现音效波浪效果）

Unity获取麦克风音量（实现音效波浪效果）

1.每个方块（Cube）为一个波浪添加脚本MusicDance

2.整体获取马克风音量大小脚本MusicManager

MusicDance

public class MusicDance : MonoBehaviour
{
    private float targetPosY;
    private float speed;
    [HideInInspector]public bool isDance;

    void Start()
    {
        RandomTargetPosY();
    }

    void Update()
    {
        if (isDance)
        {
            if (Mathf.Abs(transform.localScale.y - targetPosY) >= 1f)
            {
                transform.localScale = new Vector3(1, Mathf.SmoothDamp(transform.localScale.y, targetPosY, ref speed, Random.Range(0.2f,1f)), 1);
            }
            else
            {
                RandomTargetPosY();
            }
        }
        else
        {
            //没有声音时,从当前高度下落到正常高度
            if (Mathf.Abs(transform.localScale.y - targetPosY) >= 0.1f)
            {
                transform.localScale = new Vector3(1, Mathf.SmoothDamp(transform.localScale.y, 1f, ref speed, Random.Range(0.2f, 1f)), 1);
            }
        }
    }

    void RandomTargetPosY()
    {
        targetPosY = UnityEngine.Random.Range(1f, 12f);
    }
}

MusicManager

public class MusicManager : MonoBehaviour
{
    [SerializeField]private MusicDance[] musicDances;
    private AudioClip audioClip;
    private string strs;
    private void Awake()
    {
        audioClip = Microphone.Start(strs, true, 999, 44100);
        strs = Microphone.devices[0];
    }
    void Start()
    {
        
    }
    private void Update()
    {
        for (int i = 0; i < musicDances.Length; i++)
        {
            musicDances[i].isDance = DanceOrNot();
        }
    }

    bool DanceOrNot()
    {
        float[] datas = new float[128];
        int startPos = Microphone.GetPosition(strs) - 127;
        if (startPos < 0) return false;
        audioClip.GetData(datas, startPos);
        float max = -1f;
        for (int i = 0; i < datas.Length; i++)
        {
            if (max < datas[i])
            {
                max = datas[i];
            }
        }
        max *= 1000;
        if (max > 20)
        {
            return true;
        }
        else
        {
            return false;
        }
    }
}
