Physical Audio

Physical Audio have launched their first AU plug-ins based on pure numerical modelling.

PA1, £79, is a reverb plug-in that uses a physical model of a plate based on modal synthesis. The dynamic control of physical parameters and frequency dependent decay gives unique and creative reverberation.

PA3 Derailer, £159, is a modular network system built from metal bars and spring connections, using finite-difference time-domain numerical modelling. With 37 strike bars, 5 resonators and up to 81 connections, you can construct new nonlinear instruments.

Demo versions are available for macOS from
