QRDude - Diffuser Calculator
 

QRDude is a calculator for designing QRD diffusers.

In standard mode, it provides similar functionality to existing calculators, although it adds a few features, such as support for inverse panels.

In advanced mode, it supports the design of panels that have had their wells shifted downwards, leading to savings in panel depth or lower design frequencies. Smart well width options can yield better bandwidth.

Supports metric and imperial units.

The software was developed during discussions on another forum, but since "The Shack" is a supporter of my site, it's release is being announced here.

Version 2 supports 2D QRD panels...

Version 2.03 released to fix a bug - the text report for 2D diffusers incorrectly stated the physical well depth for normal (non-inverse) panels.

Hopefully didn't spoil the plans of too many budding QRD builders...:whistling:
Thanks to TerryJ for spotting that one!
