audiowmark is an open source solution (GPL3 or later) for watermarking
audio files. It has many features, it is robust, fast, secure and of
course we believe that the watermark is not audible for most users.
The project page provides the documentation and source code as well as
some audio demos, so you can check whether you hear a difference between
original and watermarked files.
