OS is only round. If you just want the flare rate then its
y(X) = sqrt( y0^2 + Tan(theta)^2 x X^2)
y0 is the throat radius and theta the final wall angle (which will usually be at the -6 dB angles)
theta is the half-angle of the wall-to-wall angle, I presume; i.e. from center line axis to wall?

Hello,
Hornresp can calculate both OSwaveguide (round) and Le Cléac'h horn (even mutlifacdts an square).
You then can export the profile.
You may also use the english version of my spreadsheet to calculate Le Cléac'h horns with facets. You can download it at :
