国际惯例,直接上代码- using UnityEngine;
- using System.Collections;
- using System.Collections.Generic;
-
- public class MicphoneTest : MonoBehaviour
- {
- AudioSource _audio;
- AudioSource audio
- {
- get
- {
- if (_audio == null)
- {
- _audio = gameObject.AddComponent<AudioSource>();
- }
- return _audio;
- }
- }
-
- void Start()
- {
- string[] ms = Microphone.devices;
- deviceCount = ms.Length;
- if (deviceCount == 0)
- {
- Log("no microphone found");
- }
- }
-
- string sLog = "";
- void Log(string log)
- {
- sLog += log;
- sLog += "\r\n";
- }
- int deviceCount;
- string sFrequency = "10000";
- void OnGUI()
- {
- if (deviceCount > 0)
- {
- GUILayout.BeginHorizontal();
- if (!Microphone.IsRecording(null) && GUILayout.Button("Start", GUILayout.Height(Screen.height / 20), GUILayout.Width(Screen.width / 5)))
- {
- StartRecord();
- }
- if (Microphone.IsRecording(null) && GUILayout.Button("Stop", GUILayout.Height(Screen.height / 20), GUILayout.Width(Screen.width / 5)))
- {
- StopRecord();
- }
- if (!Microphone.IsRecording(null) && GUILayout.Button("Play", GUILayout.Height(Screen.height / 20), GUILayout.Width(Screen.width / 5)))
- {
- PlayRecord();
- }
- if (!Microphone.IsRecording(null) && GUILayout.Button("Print", GUILayout.Height(Screen.height / 20), GUILayout.Width(Screen.width / 5)))
- {
- PrintRecord();
- }
- sFrequency = GUILayout.TextField(sFrequency, GUILayout.Width(Screen.width / 5), GUILayout.Height(Screen.height / 20));
- GUILayout.EndHorizontal();
- }
- GUILayout.Label(sLog);
- }
- void StartRecord()
- {
- audio.Stop();
- audio.loop = false;
- audio.mute = true;
- audio.clip = Microphone.Start(null, false, 1, int.Parse(sFrequency));
- while (!(Microphone.GetPosition(null) > 0))
- {
- }
- audio.Play();
- Log("StartRecord");
- }
- void StopRecord()
- {
- if (!Microphone.IsRecording(null))
- {
- return;
- }
- Microphone.End(null);
- audio.Stop();
- }
- void PrintRecord()
- {
- if (Microphone.IsRecording(null))
- {
- return;
- }
- byte[] data = GetClipData();
- string slog = "total length:" + data.Length + " time:" + audio.time;
- Log(slog);
- }
- void PlayRecord()
- {
- if (Microphone.IsRecording(null))
- {
- return;
- }
- if (audio.clip == null)
- {
- return;
- }
- audio.mute = false;
- audio.loop = false;
- audio.Play();
- }
- public byte[] GetClipData()
- {
- if (audio.clip == null)
- {
- Debug.Log("GetClipData audio.clip is null");
- return null;
- }
-
- float[] samples = new float[audio.clip.samples];
-
- audio.clip.GetData(samples, 0);
-
-
- byte[] outData = new byte[samples.Length * 2];
-
- int rescaleFactor = 32767;
-
- for (int i = 0; i < samples.Length; i++)
- {
- short temshort = (short)(samples[i] * rescaleFactor);
-
- byte[] temdata = System.BitConverter.GetBytes(temshort);
-
- outData[i * 2] = temdata[0];
- outData[i * 2 + 1] = temdata[1];
-
-
- }
- if (outData == null || outData.Length <= 0)
- {
- Debug.Log("GetClipData intData is null");
- return null;
- }
- return outData;
- }
-
- }
复制代码 接口都是留好的,要修改的话调用一下就可以。
声音已经导出成了byte数据,想存想传,实现一下就好,Enjoy~
