Sound samples and Codes

Approach:
A linear time-varying signal model is designed for voiced sound synthesis. The basis is modeling the excitation signal using harmonics. Below demo sounds (and code files) are provided to understand the applicability of the model in psychoacoustics for time-varying sound stimuli synthesis.
