About This Course
Physics-Based Synthesis: Modeling Vibrations and Timbre teaches a distinctive approach to making sound: rather than sampling or shaping waveforms, you model the physics that produces them. You learn how vibrating strings, membranes, air columns and resonant bodies generate timbre, and the computational methods that simulate them — from mass-spring and modal models to digital waveguides. The course connects acoustics to implementation, so you can build synthesis models that respond naturally to how they are played. You finish able to design and implement a physically modelled sound. A verified e-Certificate of competency and e-Marksheet from the Deep Science & Technology Consortium.
