I was there for a while, but made no progress. So this is my last resort! I'm trying to send a system sound (the sound that I hear on my headphones) to Skype (so that people in my conversation hear what I hear mostly). And I thought I would do it using Skype4comlib and naudio.
What I did was create a class that uses WasapiLoopbackCaptureboth WaveFileWriterto write temporary data to a WAV file and redirect audio using the SkypeSystemAudio.set_InputDevice method. But when I talk to someone and I try to start recording, the person can no longer hear me. I'm just completely silent, and no one is playing with a person.
I thought it would be better if I published the whole class, as it was easier to understand everything.
public class SkypeSystemAudio
{
public NAudio.Wave.WasapiLoopbackCapture capture;
NAudio.CoreAudioApi.MMDevice device;
NAudio.Wave.WaveFileWriter writer;
private Call CurrentCall = null;
private Skype SkypeApplet;
private const int SkypeProtocol = 9;
private bool IsRecording = false;
public string tempfilepath = System.IO.Directory.GetCurrentDirectory() + @"\temp.wav";
#region Public
public void Initialize()
{
device = NAudio.Wave.WasapiLoopbackCapture.GetDefaultLoopbackCaptureDevice();
Init();
}
public void Initialize(NAudio.CoreAudioApi.MMDevice device)
{
this.device = device;
Init();
}
public void StartRecording()
{
capture.StartRecording();
if (CurrentCall != null)
{
CurrentCall.set_OutputDevice(TCallIoDeviceType.callIoDeviceTypeFile, tempfilepath);
IsRecording = true;
}
}
public void StopRecording()
{
capture.StopRecording();
if (CurrentCall != null)
{
CurrentCall.set_OutputDevice(TCallIoDeviceType.callIoDeviceTypeFile, "");
}
}
#endregion
private void Init()
{
capture = new WasapiLoopbackCapture(device);
capture.ShareMode = NAudio.CoreAudioApi.AudioClientShareMode.Shared;
capture.DataAvailable += capture_DataAvailable;
capture.RecordingStopped += capture_RecordingStopped;
WaveFormat format = new WaveFormat(16000, 1);
writer = new WaveFileWriter(tempfilepath, format );
SkypeApplet = new Skype();
SkypeApplet.Attach(SkypeProtocol, true);
SkypeApplet.CallStatus += SkypeApplet_CallStatus;
}
void SkypeApplet_CallStatus(Call pCall, TCallStatus Status)
{
if (Status == TCallStatus.clsRinging)
{
CurrentCall = pCall;
pCall.Answer();
}
}
void capture_DataAvailable(object sender, WaveInEventArgs e)
{
if (writer != null)
writer.Write(e.Buffer, 0, e.BytesRecorded);
}
void capture_RecordingStopped(object sender, StoppedEventArgs e)
{
IsRecording = false;
}
