I have a web application that returns a byte [] from a wav file in the browser, however I need to convert these audio files to .mp3, I tried to use the Naudio library for this and I could not.

I try to use this code:

public static byte[] ConvertWavToMp3(byte[] wavFile)
{

        using(var retMs = new MemoryStream())
        using (var ms = new MemoryStream(wavFile))
        using(var rdr = new WaveFileReader(ms))
        using (var wtr = new LameMP3FileWriter(retMs, rdr.WaveFormat, 128))
        {
            rdr.CopyTo(wtr);
            return retMs.ToArray();
        }


    }

It's return an error :

Unsupported encoding format ALaw Parameter name: format
