Unity Microphone教程之 如何获取设备麦克风

1、在Unity引擎新建一个空工程，具体如下图

2、在场景中，添加一个 Button 和一个 Text，布局设置如下图

3、在工程中，新建一个脚本 OpenMicrophone，双击打开脚本进行编写，具体如下图

4、OpenMicrophone 脚本的代码和代码说明具体如下图

5、OpenMicrophone 脚本具体内容如下：using Un坡纠课柩ityEngine;using UnityEngin髫潋啜缅e.UI;[RequireComponent(typeof(AudioSource))]public class OpenMicrophone : MonoBehaviour { private AudioSource aud; private Button btn; private Text txt; private bool isHaveMicrophone = false; // Use this for initialization void Start () { aud = this.GetComponent<AudioSource>(); btn = GameObject.Find("Button").GetComponent<Button>(); txt = GameObject.Find("Text").GetComponent<Text>(); btn.onClick.AddListener(OnClickBtn); //获取麦克风设备，判断蛇摆是否有麦克风 string[] devices = Microphone.devices; if (devices.Length > 0) { isHaveMicrophone = true; txt.text = "设备有麦克风:"+ devices[0]; } else { isHaveMicrophone = false; txt.text = "设备没有麦克风"; } } private void OnClickBtn() { if (isHaveMicrophone == false) { return; } //有麦克风就打开使用麦克风 /* * public static AudioClip Start(string deviceName, bool loop, int lengthSec, int frequency); * deviceName The name of the device. * loop Indicates whether the recording should continue recording if lengthSec is reached, and wrap around and record from the beginning of the AudioClip. * lengthSec Is the length of the AudioClip produced by the recording. * frequency The sample rate of the AudioClip produced by the recording. */ aud.clip = Microphone.Start( null, true, 10, 44100); aud.Play(); }}

6、脚本编译正确，回到Unity，在场景中新建一个 GameObject，挂载脚本上去，运行场景，因为电脑没有麦克风，具体如下图

7、File - Build Settings，切换平台，打包编译，具体如下图

8、在安卓上有麦克风，运行结果如下图
