我有一个名为 AudioInput 的类：
class AudioInput
{
private WaveIn waveIn;
public delegate void DataAvailableEventHandler(byte[] data, int size);
private DataAvailableEventHandler dataAvailableProc;
public AudioInput(DataAvailableEventHandler dataHandlerProc)
{
dataAvailableProc = dataHandlerProc;
}
private void initWaveInMic()
{
Console.WriteLine("initWaveInMic");
waveIn = new WaveIn();
waveIn.BufferMilliseconds = 50;
waveIn.DeviceNumber = 0;
waveIn.WaveFormat = new WaveFormat(8000, 1);
waveIn.DataAvailable += new EventHandler<WaveInEventArgs>(waveIn_DataAvailable);
waveIn.StartRecording();
}
void waveIn_DataAvailable(object sender, WaveInEventArgs e)
{
Console.WriteLine("waveIn_DataAvailable e.buffer length: {0}", e.Buffer.Length);
dataAvailableProc(e.Buffer, e.Buffer.Length);
}
public void startNAudio()
{
this.initWaveInMic(); //start mic wavein
}
}
从调用类：
public partial class AudioTest : Form
{
Thread audioInputThread;
AudioInput audioInput;
private void audioInputCreateThread()
{
audioInput = new AudioInput(audioDataToSend);
audioInput.startNAudio();
Console.WriteLine("audioInputCreateThread at the end");
}
private void AudioTest_Load(object sender, EventArgs e)
{
// this will work
//audioInputCreateThread();
//this will not work
audioInputThread = new Thread(audioInputCreateThread);
audioInputThread.Start();
}
private void audioDataToSend(byte[] data, int size)
{
Console.WriteLine("audioDataToSend size: {0}", size);
}
}
AudioInput 类中的 waveIn_DataAvailable 回调没有被调用。任何建议我做错了什么？
