1.首先新建引用类 RecordController
public class RecordController
{
public WaveIn mWavIn;
public WaveFileWriter mWavWriter;
/// <summary>
/// 开始录音
/// </summary>
/// <param name="filePath"></param>
public void StartRecord(string filePath)
{
mWavIn = new WaveIn();
mWavIn.DataAvailable += MWavIn_DataAvailable;
// mWavIn.RecordingStopped += MWavIn_RecordingStopped; 有冲突
mWavWriter = new WaveFileWriter(filePath, mWavIn.WaveFormat);
mWavIn.StartRecording();
}
/// <summary>
/// 停止录音
/// </summary>
public void StopRecord()
{
mWavIn?.StopRecording();
mWavIn?.Dispose();
mWavIn = null;
mWavWriter?.Close();
mWavWriter = null;
}
//这个方法在调用关闭时会有冲突
private void MWavIn_RecordingStopped(object sender, StoppedEventArgs e)
{
//mWavIn?.Dispose();
//mWavIn = null;
//mWavWriter?.Close();
//mWavWriter = null;
}
private void MWavIn_DataAvailable(object sender, WaveInEventArgs e)
{
mWavWriter.Write(e.Buffer, 0, e.BytesRecorded);
int secondsRecorded = (int)mWavWriter.Length / mWavWriter.WaveFormat.AverageBytesPerSecond;
}
}
简单的调用代码。
RecordController record = new RecordController();
private void button1_Click(object sender, EventArgs e)
{
record.StartRecord("e:\rec.wav");
}
private void button2_Click(object sender, EventArgs e)
{
record.StopRecord();
}
