C# 从PC实时向Windows Phone传输音乐

我正在尝试开发一个Windows应用程序（WPF），它可以通过TCP连接（本地WiFi）在系统上播放任何内容。在接收端，我有Windows Phone 8应用程序，可以实时播放音频

我所尝试的：

成功建立了连接和数据传输工程

 void sMixListner_DataAvailable(object sender, NAudio.Wave.WaveInEventArgs e)
{
    try
    {
        if (writer != null)
        {
            SocketHandler.SocketManager.sendDataToClients(e.Buffer);
        }
    }
    catch { }
} 
 public void sendDataToClients(byte[] music)
{
    foreach (Socket client in clients)
    {
        try
        {

            client.Send(music);

        }
        catch { }
    }

}

上述代码传输从

WasapiLoopbackCapture

类接收的任何数据

在电话端，我能够正确地接收所有字节[]数据，并将其写入内存流。 MemoryStream stream=新的MemoryStream（）； public void ReceiveMessage（） {

在收到几秒钟后，我尝试将其回放为：

public void play()
{
SoundEffect soundE = new SoundEffect(stream.ToArray(), 48000, AudioChannels.Mono);
soundE.CreateInstance();
FrameworkDispatcher.Update();
isPlaying = true;
soundE.Play();
}

我听到的只是噪音。我试着用以下方式将波头写入流中（来自诺基亚开发者网站）：

录音部分是正确的，因为如果我使用

WavFileWriter

编写.wav文件，播放时声音很好

有人能帮我吗？我需要能够在我的手机上播放那个声音。

WASAPI捕获是32位IEEE浮点，而不是32位PCM，所以WAV头中的音频格式是错误的。IEEE是浮点，但在你的情况下，我建议在通过网络发送音频之前转换为16位，以节省一点带宽。

事实上lly，我以前从来没有处理过音频。你能给我一些链接来帮助我吗？我在我的（为无耻插头道歉）中详细介绍了这一点

public void play()
{
SoundEffect soundE = new SoundEffect(stream.ToArray(), 48000, AudioChannels.Mono);
soundE.CreateInstance();
FrameworkDispatcher.Update();
isPlaying = true;
soundE.Play();
}

public void WriteWavHeader(Stream stream, int sampleRate)
    {
        const int bitsPerSample = 32;
        const int bytesPerSample = bitsPerSample / 8;
        var encoding = System.Text.Encoding.UTF8;

        // ChunkID Contains the letters "RIFF" in ASCII form (0x52494646 big-endian form).
        stream.Write(encoding.GetBytes("RIFF"), 0, 4);

        // NOTE this will be filled in later
        stream.Write(BitConverter.GetBytes(0), 0, 4);

        // Format Contains the letters "WAVE"(0x57415645 big-endian form).
        stream.Write(encoding.GetBytes("WAVE"), 0, 4);

        // Subchunk1ID Contains the letters "fmt " (0x666d7420 big-endian form).
        stream.Write(encoding.GetBytes("fmt "), 0, 4);

        // Subchunk1Size 16 for PCM. This is the size of therest of the Subchunk which follows this number.
        stream.Write(BitConverter.GetBytes(16), 0, 4);

        // AudioFormat PCM = 1 (i.e. Linear quantization) Values other than 1 indicate some form of compression.
        stream.Write(BitConverter.GetBytes((short)1), 0, 2);

        // NumChannels Mono = 1, Stereo = 2, etc.
        stream.Write(BitConverter.GetBytes((short)1), 0, 2);

        // SampleRate 8000, 44100, etc.
        stream.Write(BitConverter.GetBytes(sampleRate), 0, 4);

        // ByteRate = SampleRate * NumChannels * BitsPerSample/8
        stream.Write(BitConverter.GetBytes(sampleRate * bytesPerSample), 0, 4);

        // BlockAlign NumChannels * BitsPerSample/8 The number of bytes for one sample including all channels.
        stream.Write(BitConverter.GetBytes((short)(bytesPerSample)), 0, 2);

        // BitsPerSample 8 bits = 8, 16 bits = 16, etc.
        stream.Write(BitConverter.GetBytes((short)(bitsPerSample)), 0, 2);

        // Subchunk2ID Contains the letters "data" (0x64617461 big-endian form).
        stream.Write(encoding.GetBytes("data"), 0, 4);

        // NOTE to be filled in later
        stream.Write(BitConverter.GetBytes(0), 0, 4);
    }
