以前写过一个点对点的语音对讲，说下思路发送端 音频采集 -- 音频编码 -- 网络传输接受端 网络接收 -- 音频解码 -- 音频输出需要要的话联系我，编码我直接用网上找的一个 LumiSoft 音频编码用的G.711using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms;using LumiSoft.Media.Wave;using LumiSoft.Media.Wave.Native;using LumiSoft.Net.Media.Codec.Audio;using System.Net;using System.Net.Sockets;using System.Threading;namespace testAudio{ public partial class Form1 : Form { private WaveIn m_waveIn = null; private WaveOut m_waveOut = null; private Socket socket = null; private IPEndPoint localEP = null; private IPEndPoint remoteEP = null; private AudioCodec m_audioCodec = null; private bool m_bAlive = true; public Form1() { InitializeComponent(); m_audioCodec = new G711_alaw(); localEP = new IPEndPoint(IPAddress.Any, 15888); remoteEP = new IPEndPoint(IPAddress.Parse("192.168.0.225"), 15888); socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp); socket.Bind(localEP); m_waveOut = new WaveOut(WaveOut.Devices[0], 8000, 16, 1); Thread recvThread = new Thread(new ThreadStart(OnRecv)); recvThread.Start(); } private void OnRecv() { byte [] buf = new byte[2000]; while(m_bAlive) { IPEndPoint ep = new IPEndPoint(IPAddress.Any,0); EndPoint sender = (EndPoint)ep; int nReceved = socket.ReceiveFrom(buf, ref sender); byte[] sourceBuf = new byte[nReceved]; for (int i = 0; i < nReceved; i++) { sourceBuf[i] = buf[i]; } if (nReceved <= 0) { Thread.Sleep(1); } else { byte[] decodeData = m_audioCodec.Decode(sourceBuf, 0, sourceBuf.Length); if (m_waveOut != null) { m_waveOut.Play(decodeData, 0, decodeData.Length); } } } } private void button1_Click(object sender, EventArgs e) { if (m_waveIn == null) { m_waveIn = new WaveIn(WaveIn.Devices[0], 8000, 16, 1, 500); m_waveIn.BufferFull += new BufferFullHandler(m_waveIn_BufferFull); m_waveIn.Start(); } else { m_waveIn.Dispose(); m_waveIn = null; } } private void m_waveIn_BufferFull(byte[] buf) { try { if(m_audioCodec != null) { byte[] encodeData = m_audioCodec.Encode(buf, 0, buf.Length); socket.SendTo(encodeData, remoteEP); } } catch (Exception ex) { Console.WriteLine(ex.Message.ToString()); } } }}
