概述
之前发过一篇文章http://www.php.cn/ 已经实现过了UDP的分包发送数据的功能,而这篇文章主要是一个应用,使用udp传送语音和文本等信息。在这个系统中没有服务端和客户端,相互通讯都是直接相互联系的。能够很好的实现效果。
语音获取
要想发送语音信息,首先得获取语音,这里有几种方法,一种是使用DirectX的DirectXsound来录音,我为了简便使用一个开源的插件NAudio来实现语音录取。 在项目中引用NAudio.dll
//------------------录音相关----------------------------- PRivate IWavein waveIn;
private WaveFileWrITer writer;
private void LoadWasapiDevicesCombo() {
VAR deviceEnum = new MMDeviceEnumerator();
var devices = deviceEnum.EnumerateAudioEndPoints(DataFlow.Capture, Devicestate.Active).ToList();
comboBox1.DataSource = devices;
comboBox1.DisplayMember = "FriendlyName";
}
private void CreateWaveInDevice() {
waveIn = new WaveIn();
waveIn.WaveFormat = new WaveFormat(8000, 1);
waveIn.DataAvailable += OnDataAvailable;
waveIn.RecordingStopPEd += OnRecordingStopped;
}
void OnDataAvailable(object sender, WaveInEventargs e) {
if (this.InvokeRequired) {
this.BeginInvoke(new EventHandlerWaveInEventArgs>
(OnDataAvailable), sender, e);
}
else {
writer.Write(e.Buffer, 0, e.BytesRecorded);
int secondsRecorded = (int)(writer.Length / writer.WaveFormat.AverageBytesPerSecond);
if (secondsRecorded >
= 10)//最大10s {
StopRecord();
}
else {
l_sound.Text = secondsRecorded + " s";
}
}
}
void OnRecordingStopped(object sender, StoppedEventArgs e) {
if (InvokeRequired) {
BeginInvoke(new EventHandlerStoppedEventArgs>
(OnRecordingStopped), sender, e);
}
else {
FinalizeWaveFile();
}
}
void StopRecord() {
AllChangeBTn(btn_luyin, true);
AllChangeBtn(btn_stop, false);
AllChangeBtn(btn_sendsound, true);
AllChangeBtn(btn_play, true);
//btn_luyin.Enabled = true;
//btn_stop.Enabled = false;
//btn_sendsound.Enabled = true;
//btn_play.Enabled = true;
if (waveIn != null) waveIn.StopRecording();
//Cleanup();
}
private void Cleanup() {
if (waveIn != null) {
waveIn.Dispose();
waveIn = null;
}
FinalizeWaveFile();
}
private void FinalizeWaveFile() {
if (writer != null) {
writer.Dispose();
writer = null;
}
}
//开始录音 private void btn_luyin_Click(object sender, EventArgs e) {
btn_stop.Enabled = true;
btn_luyin.Enabled = false;
if (waveIn == null) {
CreateWaveInDevice();
}
if (File.Exists(sounDFile)) {
File.Delete(soundfile);
}
writer = new WaveFileWriter(soundfile, waveIn.WaveFormat);
waveIn.StartRecording();
}
上面的代码实现了录音,并且写入文件p2psound_A.wav
语音发送
获取到语音后我们要把语音发送出去
当我们录好音后点击发送,这部分相关代码是
MsgTranslator tran = null;
public Form1() {
Initializecomponent();
LoadWasapiDevicesCombo();
//显示音频设备 config CFg = SeiClient.GetDefaultConfig();
cfg.Port = 7777;
UDpthread udp = new UDPThread(cfg);
tran = new MsgTranslator(udp, cfg);
tran.MessageReceived += tran_MessageReceived;
tran.Debuged += new EventHandlerDebugEventArgs>
(tran_Debuged);
}
private void btn_sendsound_Click(object sender, EventArgs e) {
if (t_ip.Text == "") {
MessageBox.Show("请输入ip");
return;
}
if (t_port.Text == "") {
MessageBox.Show("请输入端口号");
return;
}
string ip = t_ip.Text;
int port = int.Parse(t_port.Text);
string nick = t_nick.Text;
string msg = "语音消息";
IPEndPoint remote = new IPEndPoint(IPAddress.Parse(ip), port);
Msg m = new Msg(remote, "zz", nick, Commands.SendMsg, msg, "Come From A");
m.IsRequireReceive = true;
m.ExtendMessageBytes = FileContent(soundfile);
m.PackageNo = Msg.GetRandomNumber();
m.Type = Consts.MESSAGE_BINARY;
tran.Send(m);
}
private byte[] FileContent(string fileName) {
FileStream fs = new FileStream(fileName, FileMode.Open, FileAccess.Read);
try {
byte[] buffur = new byte[fs.Length];
fs.Read(buffur, 0, (int)fs.Length);
return buffur;
}
catch (Exception ex) {
return null;
}
finally {
if (fs != null) {
//关闭资源 fs.Close();
}
}
}
如此一来我们就把产生的语音文件发送出去了
语音的接收与播放
其实语音的接收和文本消息的接收没有什么不同,只不过语音发送的时候是以二进制发送的,因此我们在收到语音后 就应该写入到一个文件里面去,接收完成后,播放这段语音就行了。
下面这段代码主要是把收到的数据保存到文件中去,这个函数式我的NetFrame里收到消息时所触发的事件,在文章前面提过的那篇文章里
void tran_MessageReceived(object sender, MessageEventArgs e) {
Msg msg = e.msg;
if (msg.Type == Consts.MESSAGE_BINARY) {
string m = msg.Type + "->
" + msg.UserName + "发来二进制消息!";
AddServerMessage(m);
if (File.Exists(recive_soundfile)) {
File.Delete(recive_soundfile);
}
FileStream fs = new FileStream(recive_soundfile, FileMode.Create, FileAccess.Write);
fs.Write(msg.ExtendMessageBytes, 0, msg.ExtendMessageBytes.Length);
fs.Close();
//play_sound(recive_soundfile);
ChangeBtn(true);
}
else {
string m = msg.Type + "->
" + msg.UserName + "说:" + msg.NormalMsg;
AddServerMessage(m);
}
}
收到语音消息后,我们要进行播放,播放时仍然用刚才那个插件播放
//--------播放部分---------- private IWaveplayer wavePlayer;
private WaveStream reader;
public void play_sound(string filename) {
if (wavePlayer != null) {
wavePlayer.Dispose();
wavePlayer = null;
}
if (reader != null) {
reader.Dispose();
}
reader = new MediaFoundationReader(filename, new MediaFoundationReader.MediaFoundationReaderSettings() {
SingleReaderObject = true }
);
if (wavePlayer == null) {
wavePlayer = new WaveOut();
wavePlayer.PlaybackStopped += WavePlayerOnPlaybackStopped;
wavePlayer.Init(reader);
}
wavePlayer.Play();
}
private void WavePlayerOnPlaybackStopped(object sender, StoppedEventArgs stoppedEventArgs) {
if (stoppedEventArgs.Exception != null) {
MessageBox.Show(stoppedEventArgs.Exception.Message);
}
if (wavePlayer != null) {
wavePlayer.Stop();
}
btn_luyin.Enabled = true;
}
private void btn_play_Click(object sender, EventArgs e) {
btn_luyin.Enabled = false;
play_sound(soundfile);
}
在上面演示了接收和发送一段语音消息的界面
技术总结
主要用到的技术就是UDP和NAudio的录音和播放功能
