我正在使用从麦克风录制的 Visual C# Studio 制作程序。
我想录制几分钟,但是当我尝试录制时,它会在录制 5 秒后显示“缓冲区已满”的错误。
这是我正在使用的代码:
private void button2_Click(object sender, EventArgs e) //Play Button
{
fileName = "lastReplay.wav";
FileStream FS_Write = File.OpenWrite("lastReplay.wav");
FS_Write.Close();
int deviceNumber = sourceList.SelectedItems[0].Index;
sourceStream = new NAudio.Wave.WaveIn();
sourceStream.DeviceNumber = deviceNumber;
sourceStream.WaveFormat = new NAudio.Wave.WaveFormat(44100,
NAudio.Wave.WaveIn.GetCapabilities(deviceNumber).Channels);
NAudio.Wave.WaveInProvider waveIn = new
NAudio.Wave.WaveInProvider(sourceStream);
sourceStream.DataAvailable += new EventHandler<NAudio.Wave.WaveInEventArgs>
(sourceStream_DataAvailable);
waveWriter = new NAudio.Wave.WaveFileWriter(fileName, sourceStream.WaveFormat);
sourceStream.StartRecording();
}
private void sourceStream_DataAvailable(object sender, NAudio.Wave.WaveInEventArgs e)
{
if (waveWriter == null) return;
waveWriter.Write(e.Buffer, 0, e.BytesRecorded);
waveWriter.Flush();
}
有谁知道是什么问题?谢谢。
