.net - 直接从 WAV 文件发送到 DirectShow 声卡

Question

我正在使用 VB.net 集成将波形文件发送到特定扬声器（正是示例文件中所做的）。但是，我在解码示例文件中实际完成的内容时遇到了麻烦，因为我要查找的内容要简单得多。

将 WAV 文件发送到扬声器的代码是什么 我如何打开和解码所述波形文件？

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    Dim wavefile As New NAudio.Wave.Mp3FileReader("C:\Users\iqm2admin\Desktop\Pause.mp3") 'The Audio MP3 file you want to play
    Dim waveout As New NAudio.Wave.WaveOut() 'Create Wave Object
    Dim devicecount As Integer = NAudio.Wave.WaveOut.DeviceCount() 'Count the devices
    Dim TestString As String = "Speaker description" 'The desciption of the speaker you want to play to
    Dim SDevice As String = Nothing
    Dim DeviceNum As Integer
    For i As Integer = 0 To devicecount - 1
        SDevice = NAudio.Wave.WaveOut.GetCapabilities(i).ProductName
        If TestString.ToLower = SDevice.ToLower Then                   'Find the speaker you want to play to
            DeviceNum = i
        End If
    Next
    waveout.DeviceNumber = DeviceNum ' set the device to play to
    waveout.Init(wavefile)
    waveout.Play() 'play the file
End Sub
