Download New SndObj Library Classes for Sinusoidal Modeling We present an object-oriented implementation for sinusoidal modelling based on the C++ Sound Object Library (SndObj). We outline the background to this analysis/synthesis technique and its inclusion in many well known methods of speech and music signal processing. Incorporation of such a well known technique into the SndObj library will enable the development of further audio processing techniques such as vocoding, time and pitch scaling and cross-synthesis on an object-oriented development platform.
