问题:

In my project I am receiving mp3 data in a byte array. I want to convert that data to wav format and store it in another byte array. I searched internet for mp3 to wav converters but all of them support file to file conversion. None of them seems to take raw data as inputs. Is there any way I can achieve this in C# ?
Here is the protoype of the function I am trying to create.

   bool ConvertToWav(byte[] buffer){
      //Do some processing and store the wav data in buffer2
      Buffer.BlockCopy(buffer2,0,buffer,0,buffer.Length-1);
   }

This is quite the late response but I just figured it out myself. There is this NuGet package called NAudio, https://www.nuget.org/packages/NAudio/ This provides awesome functionality for what you want to do.

    using NAudio.Wave;        

    private static void ConvertMp3ToWav(string _inPath_, string _outPath_)
    {
        using (Mp3FileReader mp3 = new Mp3FileReader(_inPath_))
        {
            using (WaveStream pcm = WaveFormatConversionStream.CreatePcmStream(mp3))
            {
                WaveFileWriter.CreateWaveFile(_outPath_, pcm);
            }
        }
    }

There you go.
