[英]wrong .wav format recording audio NAudio library
im having problems when trying to record sound from microphone in my wpf application. 即时通讯在我的wpf应用程序中尝试从麦克风录制声音时遇到问题。 here's my code:
这是我的代码:
public NAudio.Wave.WaveFileWriter wav_writer = null; // snemanje
public WaveIn strim;
private void snemanje_Click(object sender, RoutedEventArgs e)
{
strim = new WaveIn();
strim.WaveFormat = new WaveFormat(44100, 0);
SaveFileDialog svg = new SaveFileDialog();
svg.Filter = "*WAV File (*.wav)|*.wav;*";
svg.ShowDialog();
strim.DataAvailable += new EventHandler<WaveInEventArgs>(waveInStream_DataAvailable);
wav_writer = new WaveFileWriter(svg.FileName, strim.WaveFormat);
strim.StartRecording();
}
public void waveInStream_DataAvailable(object sender, WaveInEventArgs e)
{
wav_writer.WriteData(e.Buffer, 0, e.BytesRecorded);
wav_writer.Flush();
}
everything works perfectly and the file is saved in the projects location, but i can not oppen it. 一切正常,文件保存在项目位置,但我不能拒绝它。 it says that it is a wave file but everytime i want to play it, it says that i must find codecs for playing in that format (but there arent any).
它说它是一个wave文件,但是每次我要播放它时,它都说我必须找到要以这种格式播放的编解码器(但是那里没有任何文件)。
Don't create a WaveFormat with 0 channels. 请勿创建具有0个通道的WaveFormat。 You should use 1 for mono or 2 for stereo.
您应将1用于单声道或将2用于立体声。
// create a mono 44.1kHz wave format
new WaveFormat(44100, 1);
