How to play a MP3 file using NAudio

Question

WaveStream waveStream = new Mp3FileReader(mp3FileToPlay);
var waveOut = new WaveOut();
waveOut.Init(waveStream); 
waveOut.Play();

This throws an exception:

WaveBadFormat calling waveOutOpen

The encoding type is "MpegLayer3" as NAudio.

How can I play a mp3 file with NAudio?

Try like this:

class Program
{
    static void Main()
    {
        using (var ms = File.OpenRead("test.mp3"))
        using (var rdr = new Mp3FileReader(ms))
        using (var wavStream = WaveFormatConversionStream.CreatePcmStream(rdr))
        using (var baStream = new BlockAlignReductionStream(wavStream))
        using (var waveOut = new WaveOut(WaveCallbackInfo.FunctionCallback()))
        {
            waveOut.Init(baStream);
            waveOut.Play();
            while (waveOut.PlaybackState == PlaybackState.Playing)
            {
               Thread.Sleep(100);
            }
        }
    }
}
