PA1 Dynamic Plate Reverb is an effect plug-in that uses a pure numerical model to recreate the classic sound of plate reverbs

Adjustable plate

Vary the plate dimensions up to 3m x 2m, adjust the tension, and choose from 6 different materials such as Gold and Titanium.

Frequency-dependent decay

Shape your reverb with frequency-dependent T60 decay times over 8 octave bands, from 0.3 to 10 seconds.

Variable pickups

Change the left and right channel pickup positions across the plate to suit the input sound.

Shape your sound

Truly musical reverberation


Pure Numerical Modelling

PA1 does not use impulse responses or delay networks. Instead we start from a purely mathematical description, the Kirchhoff plate equation. This gives the displacement in terms of size, thickness, and tension, as well as the properties of the chosen material (Young's modulus, density, and Poisson's ratio). Using this description we calculate 6,000 modes of vibration for the system to give a dense and rich reverberant quality. From there we perform a real-time integration to compute the displacement of the plate, with the decay times across the 8 octave bands of the modes.

Free to use in Demo mode

PA1 is free to use in Demo mode. The output is cut for several seconds each minute.
