Ath - The generator of state-of-the-art waveguides
Ath is a highly parametrizable acoustic waveguide design tool and BEM mesh generator. By extending the work of Dr. Earl Geddes, a new waveguide formula was developed, terminating what is known as the oblate spheroidal (OS) waveguide into a flat baffle. This perfectly smooth finite contour proved to provide excellent performance of controlled directivity without any noticeable signs of diffractions or reflections.
Create your own model and test it with BEM analysis using R&D Team's ABEC (*). Ath will generate all the necessary files automatically.

(*) Since ABEC changed to AKABAK in the meantime and there seem to be some compatibility issues, you may still want to use the old version of ABEC 3 until the issue is resolved.
