	Hey hey, the m_aerosound opcode has been in the making for a while. It's based on the work by Rod Selfridge[1] on "realtime synthesis of aeroacoustic sounds" at Queen Mary University of London. The opcode models wind blowing past a cylinder (which could of course be a wire). It models the sound as well as the placement in space. the original model is written for PureData and can freely be downloaded from Rod's blog[1]. The Csound opcode is here: http://juliencoder.de/sound/m_aerosound-0.5.zip Comments, suggestions for improvements and criticism of any kind is very welcome. My great thanks go to Rod Selfridge for his constant support in this conversion, since I couldn't read the formulas in his publications. Accessibility and maths is a topic still very much in development.

	Very convincing output, much richer than filtered noise that I've used in the past.

	Hi Hlöðver and Anton, thanks for the kind words. I hope you can do something with it. Careful though: due to the involved physics the output level has a VERY WIDE dynamic range.
