如何显示录制时间，而录制与NAudio

本文关键字：NAudio 时间 何显示 显示 | 更新日期: 2023-09-27 18:01:58

我试图在使用c# windows窗体定时器录制NAudio库时显示录制时间。这就是我想要实现的代码。我有这个代码的问题是定时器的定时不匹配记录的长度。我要定时器的定时和记录定时同步!

  private void buttonStart_Click(object sender, EventArgs e)
    {
        buttonStart.Enabled = false;
        buttonStop.Enabled = true;
        waveSource = new WaveIn();
        waveSource.WaveFormat = new WaveFormat(44100, 2);
        waveSource.DataAvailable += new EventHandler<WaveInEventArgs>(waveSource_DataAvailable);
        waveSource.RecordingStopped += new EventHandler<StoppedEventArgs>(waveSource_RecordingStopped);
        waveFile = new WaveFileWriter(@"C:'one'Test0010.wav", waveSource.WaveFormat);
        waveSource.StartRecording();
      } 
  void waveSource_DataAvailable(object sender, WaveInEventArgs e)
    {
        if (waveFile != null)
        {
            timerSoundRecord.Start();
            waveFile.Write(e.Buffer, 0, e.BytesRecorded);
            waveFile.Flush();
            var lenght = (int)(waveFile.Length / waveFile.WaveFormat.AverageBytesPerSecond);
            if (lenght == 6)
            {
                timerSoundRecord.Stop();
                waveSource.StopRecording();
                buttonStop.Enabled = false;
                buttonStart.Enabled = true;
            }

        }
    }
private void timerSoundRecord_Tick(object sender, EventArgs e)
    {
        if (progressBarRecordSound.Value != 6)
        {

            seconds = seconds + 1;
            labelTime.Text = @"00:0" + seconds;
            progressBarRecordSound.Value++;
        }
        else
        {
            timerSoundRecord.Stop();
        }
    }

你在每次滴答时更新timesoundrecord_tick内的秒数。这是非常不同的测量。

让你的长度变量从方法waveSource_DataAvailable全局，然后在timerSoundRecord_Tick中检查它，而不是使用你增加的变量秒。

  private void buttonStart_Click(object sender, EventArgs e)
{
    buttonStart.Enabled = false;
    buttonStop.Enabled = true;
    waveSource = new WaveIn();
    waveSource.WaveFormat = new WaveFormat(44100, 2);
    waveSource.DataAvailable += new EventHandler<WaveInEventArgs>(waveSource_DataAvailable);
    waveSource.RecordingStopped += new EventHandler<StoppedEventArgs>(waveSource_RecordingStopped);
    waveFile = new WaveFileWriter(@"C:'one'Test0010.wav", waveSource.WaveFormat);
    waveSource.StartRecording();
    timerSoundRecord.Start();
  } 
int length = 0;
void waveSource_DataAvailable(object sender, WaveInEventArgs e)
{
    if (waveFile != null)
    {           
        waveFile.Write(e.Buffer, 0, e.BytesRecorded);
        waveFile.Flush();
        var lenght = (int)(waveFile.Length / waveFile.WaveFormat.AverageBytesPerSecond);
        if (lenght == 6)
        {
            timerSoundRecord.Stop();
            waveSource.StopRecording();
            labelTime.Text = @"00:0" + length;
            progressBarRecordSound.Value++;
            buttonStop.Enabled = false;
            buttonStart.Enabled = true;
        }
    }
}
private void timerSoundRecord_Tick(object sender, EventArgs e)
{
        labelTime.Text = @"00:0" + length;
        progressBarRecordSound.Value++;
}
