2D quadratic residue diffuser
Here is a special acoustic diffuser with total symmetry which frequency changes over the radial axis. Starting from a common 2D definition, we use quarters with 15+1 elements.
Acoustic diffuser with dedicated frequency.
Now the frequency is slightly lowerde over the axis leading to an expanded designs:
Finally a window is applied on to the element sizes leading to a smoothed frequency behaviour.
