Qt wrappers for codec2 library

Qt wrappers for codec2 library

About

As I wrote in previous post I was amazed by codec2 (w:codec2) library for speech encoding. You can find more documentation about how to build codec2 library on Windows in my previous post:

You can find more information about codec2 on home page of codec2 here:

Next I want to write wrappers for Qt and test this library with my speech.  See below and you will find more.
