About this project

[hesa2020]

Hey this is a really cool project, I was wondering where do you find the maths algorithm to calculate the frequency response I would like to add a few charts to this tool like Cone Excursion and Air velocity but I just cant find the formulas anywhere.

Also I would like to possibly contribute to this tool I could write a box designer using an opengl canvas and possibly port the whole tool to my iPad to make it easier to work at my workbench.

Thanks for your interest !
I found the formulas both on the web and on my old acoustic lessons when I was a student. For the web, you can look at the wayback machine here (this is not anymore in present):

The code in QSpeakers is in system.cpp

I'm also looking for cone excursion, but can't find it for now...

Making a box designer would be really cool ! You can look at Qt's scene: https://doc.qt.io/qt-5/qgraphicsscene.html for 2D rendering, or indeed OpenGL for 3D rendering. Qt has OpenGL facilities: https://doc.qt.io/qt-5/qtgui-openglwindow-example.html

Let's keep in touch.
