How to simultaneously play 2 audio files in C#, each on its own speaker?

Question

Audio

The situation is as follows, there are 2 speakers connected to the same PC, but located in different rooms.
Under a certain condition, the application (windofs forms) must play 2 audio files, each will be heard only from its own speaker.
Downloaded several different libraries - NAudio, LibZplay. It turns out to display the file on one column, the volume of the second is reduced. And how to do for two files, I'll never know.

Answer 1

Understood:

var input1 = new WaveFileReader(файл1.wav");
var input2 = new WaveFileReader(файл2.wav");                   
 var waveProvider = new MultiplexingWaveProvider(new IWaveProvider[] { input1, input2 }, 2);
waveProvider.ConnectInputToOutput(0, 0);
waveProvider.ConnectInputToOutput(1, 1);

WaveOut Device = new WaveOut(); 
Device.Init(waveProvider);
 Device.Play();

And everything is fine.

Answer 2

You need to make one of these two files - it will have the first file in the left channel, and the second in the right. Like here , just the other way around.
