Abstract

A problem of design of a system for real-time voice watermarking using a digital signal processor (DSP) is studied and presented in this paper. The authors prepared and compared three versions of the considered system using different types of data formats (fixed-point and floating-point) and various ways of programming (Matlab/Simulik compiler for Code Composer Studio and plain C/C++ programming).
