how to decode amr files using c#.net

Question

I need to decode amr format to pcm format, which is later converted to mp3 using c#.net. But I am hardly finding any library to do so. It seems with NAudio it is not possible. Is there any c# based open source library which can be used to decode this format files?. Presently I am working on windows server 2012(64 bit).

NAudio Code:

public void Decode() 
{
 .....
 var result= new MediaFoundationReader("..\\sample.amr");
 // later converted to  mp3 here
}

You're unlikely to find a C# decoder for AMR files. I'd recommend just finding a command-line utility that you can call to convert to PCM. For example, it looks like sox can be used to decode AMR.

It looks you two guys are doing the same thing: How to convert amr files to mp3 using C#

You typically need to have a [third party] AMR decoder installed and integrated into Windows API (ACM, DirectShow, Media Foundation). Then you will use your favorite library around this API, such as NAudio.

Example of AMR decoder: MONOGRAM AMR Pack.
