Improved Carillon Synthesis

with Mark Rau and Orchisama Das

An improved and expanded method for carillon bell synthesis is proposed. Measurements of a carillon bell and its clapper were made to serve as the basis for an efficient synthesis framework. Mode frequencies, damping, and amplitudes are used to form a modal model fit to measurements. A parameterized clapper interaction model is proposed to drive the bell model, reproducing variation of timbre as the bell is played in different dynamic ranges. Reverberation of the belfry was measured from several listener perspectives and an efficient modal reverberation architecture is shown to model the sound of the bell from locations inside and outside the belfry.
