Question

我知道NAudio.UWP正在进行中，但最新版本（1.8）似乎确实能够编写.wav。

    private IWavePlayer player;
    private WaveStream reader;
    private IWaveIn recorder;
    private MemoryStream recordStream;
    private IRandomAccessStream selectedStream;

    private void Record()
    {
       if (recorder == null)
        {
            recorder = new WasapiCaptureRT();

            recorder.RecordingStopped += RecorderOnRecordingStopped;
            recorder.DataAvailable += RecorderOnDataAvailable;               
        }

        if (reader != null)
        {
            reader.Dispose();
            reader = null;
        }

        recorder.StartRecording();

    }   

 private async void RecorderOnDataAvailable(object sender, WaveInEventArgs waveInEventArgs)
    {
        Debug.WriteLine(waveInEventArgs.BytesRecorded);
        if (reader == null)
        {
            recordStream = new MemoryStream();
            reader = new RawSourceWaveStream(recordStream, recorder.WaveFormat);                
        }      

        await recordStream.WriteAsync(waveInEventArgs.Buffer, 0, waveInEventArgs.BytesRecorded);                      
    }

在哪里/如何创建存储文件名，路径等？没有目标参数...这是示例附带的唯一代码。

Answer 1

在哪里/如何创建存储文件名，路径等？

这实际上取决于您的要求。例如，您可以使用固定名称和时间戳来命名您的音频文件。

var file = KnownFolders.MusicLibrary.CreateFileAsync("song"+DateTime.Now.ToString("yyyy-MM-DD-hh-mm-ss")+".wav",CreationCollisionOption.GenerateUniqueName);

Answer 2

您可以将记录流复制到新文件流中。例如：

 var file = await KnownFolders.MusicLibrary.CreateFileAsync("test.wav");
 using (var stream = await file.OpenAsync(FileAccessMode.ReadWrite))
 {
       recordStream.CopyTo(stream.AsStream());
 }

NAudio.UWP记录，写.wav
