2 my problems with 3DSound (Xaudio2 + X3daudio)

[Mitra-M]

1 - I have made a simple InputPlayer using WasApi. and I want redirect the WasApi source to Xaudio2 and back it in runtime.

I tried this:

 ```
     source = new SoundInSource(soundIn) { FillWithZeros = true };
     soundOut = new WasapiOut(true, AudioClientShareMode.Shared, 1, ThreadPriority.Highest);
. . . . . 
 private void btnSwitchTo3D_Click(object sender, RoutedEventArgs e)
  {
         if (soundOut != null)
            {
                soundOut.Stop();
                 xaudio2 = XAudio2.CreateXAudio2();
                 masteringVoice = xaudio2.CreateMasteringVoice(2, 48000, selectedDevice.DevicePath);
                channelMask = masteringVoice.ChannelMask;
                _destinationChannels = masteringVoice.VoiceDetails.InputChannels;
                streamingSourceVoice = new StreamingSourceVoice(xaudio2,new InterruptDisposingChainWaveSource( source.ToWaveSource()));
              StreamingSourceVoiceListener.Default.Add(streamingSourceVoice);
              streamingSourceVoice.Start();
           }
    }

above code is working fine.

Now,I want to redirect (back) the `source` to the WasApi  :

 private void btnBackToWasapi_Click(object sender, RoutedEventArgs e)
  {
       if (streamingSourceVoice != null )
            {
                    streamingSourceVoice.Stop();
                    StreamingSourceVoiceListener.Default.Remove(streamingSourceVoice);
                    streamingSourceVoice.Dispose();
                    masteringVoice.Dispose();
                    xaudio2.Dispose(); 
                   soundOut.Play();
            }
     }

But the above code does not work sometimes, because the source is disposed.(sometimes)

I'v used `InterruptDisposingChainWaveSource` to prevent disposing but not affect.

Please tell me how to do that?

**2 -**  to simulate a real 3DSound we need to set  LPF and reverb in X3DAudio ,But there is not any good c# sample (I can't find at least) in the internet.

I found a great [XAudio2Sound3D sample](https://github.com/walbourn/directx-sdk-samples/tree/master/XAudio2/XAudio2Sound3D) in c++ (without using XAPO )  , that is what I need ,but I can't do that with cscore.

Please Please Please add a X3DAudio sample to do it or add LPF and reverb effects to X3DAudioSample.

Thank you in advance!

I've planed to add these missing features for a quite long time. I haven't forgot that yet. But currently there are some other priorities.

Okay, I'm waiting.

And I pray that sooner reach the turn 3Dsound.

Thank you!

I'll close it for now. But it is marked as "open feature request". Hopefully we'll come back to this.

Is this still planned? I would love to use effects in CSCore for XAudio2 too. Thats actually a real missing thing and would be great to get rid of SharpDX.

What exactly would you like to use? The effects and 3d audio are implemented in cscore.

Sorry I misread the original post as I thought it covers that topic. But the Reverb from XAudio2.fx would be great as it offers a lot more parameters to edit. Do you plan to implement it some day?
