I had intended to also include the possibility of using a series of FRD response files consisting of an array for horizontal and and array for vertical, to model things like horns or drivers that aren't symmetrical and don't resemble circular pistons. So far, so good, I get reasonable looking results for things like line arrays and D'Appolito configurations. But please, limit or even resist making requests or telling me what you want this to do - I REALLY don't want to be the programmer for something 'designed by committee', I have enough trouble keeping up with my own plans for this! And it's also too early to be overwhelming me with buglists!Īt present, XSim3D only handles drivers that can be modeled as circular pistions, using the well-known far-field pressure formula (easy to find via Google) to get their off-axis frequency responses.

Someone is going to ask, so yeah, you can download it to play with it from. (NOTE, I'm not trying to handle baffle edge diffraction, at least not for a while - that's a bigger battle for another day.)Ī lot of this is working (at least somewhat), but I've kind of run into a snag, and I don't know if it is something that can be recovered from. Because we can't just pretend that only the on-axis response matters. The idea is that you can move the location of a virtual microphone (actually by holding the 'mic' still and spinning the room in the GUI!) to get a simulation of the off-axis response of the speaker due to differing driver locations and off-axis driver responses.

I've been working on a major revision of Xsim, to also include the effects of driver positioning and room boundary effects.
