Performing Convolution and Auralization in COMSOL Multiphysics®

Application ID: 118191

These models introduce how to perform convolution via the convolution integral, discrete convolution, and convolution theorem. Specifically, they show how to implement convolution by applying these methods to the low-pass filtering of a room impulse response (IR) and the auralization of a trumpet sound in a small concert hall.

To learn more about these model, see our accompanying blog post "Convolution and Auralization for Room Acoustics Analysis".
