![]() Indeed, seeing some graphs simultaneously is beneficial. Even voice coil inductance is not quite a real inductance, but something more like "semi-inductive". Benson, another famous Australian ), although effect is not severe, that extra transfer function pole is virtually on origin of s-plane, using typical losses. Also, modelling leaks in closed box makes some difficulties, because it turns nice second order system into third order one (this is predicted also by Mr. I believe that is one goodie of WinISD pro.īecause all programs are based on same (probably) electroacoustic models, results should agree, but there is one degree of freedom, air properties can be different (main reason why various programs give you different port lengths with same inputs). Another features we added during last release 0.50a6, is the calculation of maximum SPL with Xmax and Pe restrictions, and printing of graphs. What Isaac said of stuffing (Qa and box volume) applies also on WinISD pro, enclosure quality factors are found under "advanced ->" button. I just wanted to know have you tried WinISD pro? Link Removed is good for T/S extraction as well as crossover simulation. I just need to change SubSim's code to ease the pain in integrating the above-mentioned features and other planned features for that matterĮverything you'd need is already out there.Īs well as Baffle Diffraction Simulator and other great tools from the FRD Group 6th/8th order box optimiser code is a bit slow, so that needs more work. Box optimiser - also working and in software form. The equations and ideas are written on pieces of paper here somewhereģ. up to 8th-order LP/HP active filter - Sallen-Key-based for circuit simplicity. 10-band equalizer - this one is now in software formĢ. But the following features will be added soon. Unfortunately, I'm still a college student, so spare time for developing SubSim and xoversim is rather limited. This is especially educational for beginners as one can conveniently see the relationship between each curve type. Moreover, SubSim uses only one graph space to display any or all of the curves. What's neat with SubSim is that you can feed it acoustic measurements of your listening room and use it to display your design's in-room response. SubSim, on the other hand, well it's a different approach as Janne mentioned SubSim will let you simulate all the supported boxes at the same time, but not multiple instances of the same box type at least not yet. But I would not recommend buying the latest Excel version just for that.Īside from what Janne has mentioned, winISD Pro has a user-friendly user-interface. Without the annoying Excel errors IMO Unibox is great for displaying the impulse response of your design. Offered features is what counts, I would say. ![]() So accuracy over the other is irrelevant, I think. Both winISD Pro and Subwoofer Simulator are based on electroacoustics and I think, don't quote mo on this, Unibox is based on electroacoustics or equivalent circuits as well.
