名称“Microphone”在当前上下文单元中不存在

Question

名称“麦克风”在当前上下文中不存在。在window 8中打开unity(版本5.6.0f3)项目时遇到此错误。

RequireComponent (typeof (AudioSource))公共类SingleMicrophoneCapture : MonoBehaviour {

    //A boolean that flags whether there's a connected microphone
    private bool micConnected = false;

    //The maximum and minimum available recording frequencies
    private int minFreq;
    private int maxFreq;

    //A handle to the attached AudioSource
    public AudioSource goAudioSource;
    public AudioClip recordedAudioClip;
    [HideInInspector]
    public AudioClip myAudioClip;
    //public Text fileExist;
    bool startRecording = false;

    public Sprite[] recordingSprites;
    public int count =0;
    //int recordedFileCount =0;
    public bool isDefaultAudioPlaying = false;
    [SerializeField]
    public Sprite[] playSprites;
    public GameObject forwardButton;
    public GameObject backwardButton;
    public GameObject playButton;
    public GameObject replayButton;
    //Use this for initialization
    public AudioClip[] allAudioClips;
    public string storyName;
    float[] samples;
    public Dictionary<int,float> recordedClipDict;
    void Start() 
    {
            //ReplayButtonClicked ();
        //Check if there is at least one microphone connected

        recordedAudioClip= null;
        if(Microphone.devices.Length <= 0)

            {
            //Throw a warning message at the console if there isn't
            Debug.LogWarning("Microphone not connected!");
        }
        else //At least one microphone is present
        {
            //Set 'micConnected' to true
            micConnected = true;

            //Get the default microphone recording capabilities
            Microphone.GetDeviceCaps(null, out minFreq, out maxFreq);

            //According to the documentation, if minFreq and maxFreq are zero, the microphone supports any frequency...
            if(minFreq == 0 && maxFreq == 0)
            {
                //...meaning 44100 Hz can be used as the recording sampling rate
                maxFreq = 44100;
            }

            //Get the attached AudioSource component
            goAudioSource = this.GetComponent<AudioSource>();
          // mainAudioSource = Camera.main.GetComponent<AudioSource> ();
        }

    }

如何解决这个问题。

Answer 1

您收到此错误是因为您使用的平台不支持Microphone应用编程接口。WebGL是不支持Microphone应用编程接口的平台之一。除了WebGL之外，可能还有其他平台没有麦克风支持。

从构建设置切换到支持Microphone应用编程接口的平台。

你也可以使用Unity的preprocessor directives来保护它，并确保在使用不支持它的平台或没有实现它的平台时，Microphone API是而不是。

#if !UNITY_WEBGL
//YOUR Microphone CODE HERE
#endif

如果你真的需要WebGL的麦克风，可以制作一个插件或者使用this one(不免费)。

Answer 2

我们看不到您的using语句。

但看起来你好像不见了

using UnityEngine.AudioModule;
