Synthesizing musical notes of Harmonium using Spectral Domain Modeling

Digital Sound Synthesis has been an exciting field of research over the last two to three decades. The idea is mainly to generate sound artificially using a system. A lot of work has been done in the past for synthesis of musical tones of stringed instruments. In this work, attempt is made for synthesizing Harmonium music using the techniques of Physical Modeling based on Digital Waveguides. In particular, the seven basic musical notes of the Harmonium are synthesized using which any Harmonium music can be generated. An analysis-synthesis approach is used for model-based good quality music synthesis. Timefrequency representations, particularly STFT are used for analysis of the natural music using which model parameters are estimated. Significant improvement is achieved in the quality of synthesis by extracting the excitation signal from the original music itself.
