AbstractCurrent sound hybridization techniques are based on the exciter-resonator model, where the spectral characteristics of a sound (resonator) are applied to another one (exciter). The traditional implementations use Linear Predictive Coding, the Short-time Fourier Transform (STFT) or the Phase Vocoder and the most common application is to hibridize speech (used as a resonator) with a spectrally rich sound (used as a exciter), resulting into the characteristic "talking sound" effect. The use of a more powerful sound representation model like Spectral Modeling Synthesis (SMS) [Serra and Smith, 1989] takes the concept of sound hybridization beyond the traditional exciter-resonator model. This paper starts by describing a hybridization system based on the STFT and then it presents the system based on SMS.
