We describe a method to model resonant bodies from measured Impulse Responses. We use the Filter Diagonalisation Method to extract the prominent modes of the resonant body in order to calculate IIR filter coefficients. This modelling allows for real-time parametric convolution of instrument input signals with the chosen resonant body’s IR. A case study is presented where a bank of filters modelling a measured cello IR is implemented in embedded hardware and used in a 3D-printed cello instrument. This study demonstrates accurate modelling of the measured IR, with the addition of parametric control of parameters such as decay rate and modal frequencies.
