Using NAudio for .NET how do I remove the silence wave at the end of mp3 file?

I am working on a C# WPF application that groups a group of words (from about 17,000 words) together and generates a playlist matching mp3 files (each mp3 file being a word).

Currently each mp3 file has a random silence between 1 second to 30 seconds at the end of its wave.

I want to be able to programmatically remove the silence wave from the end of the file.

Using NAudio for .NET how do I remove the silence wave from the end of mp3 file?
