That’s the code of the UDO I have, working on macOS and on Windows (I developed my csd there):

```
/*
m_aerosound - Aeroacoustic semi-physical model
DESCRIPTION
Model the effect of wind blowing past a cylinder.
SYNTAX
aleft, aright m_aerosound kairspeed, kdiametre, klength, kelevation, \
kazimuth, kdistance
INITIALIZATION
PERFORMANCE
kairspeed - speed of the wind in m/s (may not be 0!)
kdiametre - diametre of the cylinder in m (may not be 0!)
klength - length of the cylinder in metres
kelevation - elevation angle between listener and sound source (in Radians)
kazimuth - Azimuth angle between listener and sound source (in Radians)
kdistance - Distance between listener and sound source (in Metres)
CREDITS
Written in Csound by Jeanette C., original proposition, research and PureData
code by Rod Selfridge as part of his thesis at Queen Mary University of
London, many thanks to him for his untiring support and generousity!
