What exactly do you want to be in the resulting text file?

Is it the song/speech text?
A description of how the file sounds?
Artist/Title and so on?

A Wave file does not contain the "text" of a song in the sense I think you mean - it contains a series of frequency and duration values which can recreate the original sound, which may not be related to "words" at all: it could be the sound of a chainsaw, or a whale song, or a car engine - none of which are describable in words!

If you are trying to convert a file to text to transfer it via a text interface and recreate the original file from that at the other end, then that's different, and there are a number of ways to do that.

It does not make any sense to convert wav to text.but the answer could be something like this:

C#

var data = File.ReadAllBytes("path");

var text = System.Text.Encoding.ASCII.GetString(data);
