Play stereo sound as mono sound for different channel using c#.net

Question

I want to play a stereo sound in the following manner using c#.net

It’s a stereo track: Make it possible to hear only the L or only the R channel or both channels simultaneously. If you play only on channel put the audio out in mono so that you can hear the one channel in either speakers or headphones

Thanks in advance for any help

Somewhere i read that we can do this by VLC player.By select Audio-> Audio Channels -> Right or Left . But ,how can i do this via programming in c#. Is there anybody who can help me ?? — SR Dusad

In Alvas.Audio you need use AudioCompressionManager.MergeStereo and AudioCompressionManager.SplitStereo methods

See pseudo code below

    AudioCompressionManager.SplitStereo(stereo, left, right);

    PlayerEx plex = new PlayexEx(); 
    plex.Done += new PlayerEx.DoneEventHandler(plex_Done);   
    plex.OpenPlayer(format);      
    plex.StartPlay();

    enum State {    Left,    Right,    Both }

    void plex_Done(object sender, DoneEventArgs e) {    
      byte[] left50ms = Cut(left, 50);    
      byte[] right50ms = Cut(right, 50);    
      switch (State)    {
        case State.Left:
          plex.AddData(AudioCompressionManager.MergeStereo(left50ms, left50ms));
        break;
        case State.Right:
          plex.AddData(AudioCompressionManager.MergeStereo(right50ms, right50ms));
        break;
        case State.Both:
          plex.AddData(AudioCompressionManager.MergeStereo(left50ms, right50ms));
        break; 
}
