Multiple-Degree of Freedom Cavity Resonator Diary

User's guide is now attached to simulation softwae. This software can simulate single & double bass-reflex, and standard MCAP-CR up to three subchambers! Try it and give me your feedback! Download Page

Information of QNDR System is released. QNDR details had been released ago but in Japanese only. Now you will see my web page. See Project MCAP-CR .

Multiple Degree of Freedom Cavity Resonator Loudspeaker page is renewed. Old pages are archived and you can as well as view again. Update will be done on renewed pages only. Visit Project MCAP-CR .

Multiple-Degree of Freedom Cavity Resonator Project page is being restructed. Currently temporary page is placed as: http://mcap.web.fc2.com/indexe.html It is under construction but please visit it. You will not get hurt.

I will begin restructuring my website. My website may have been too much technical for most readers. I am reorganizing the site design first, but it is not enough for restructuring. Please keep in touch! Multiple-Degree of Freedom Cavity Resonator Project

More than one year have passed since MCAP-CR simulator CUI version was released. I recently released minor change version with Windows Binary Executable file. New function is: Number of sub-chambers is not limited to 3 but 1, 2 or 3. You can now use this simulator to double-bass-reflex systems and also single-bass-reflex systems. For single-bass-reflex systems, increase volume of sub-chamber up to maximum (now 10 cubic-meters). This is just small change. In the next release, dumping coefficient can be set from GUI. Now one who can handle C language can modify source code and make damping coefficients adjustable, but original code sets all damping coefficients be zero. Enjoy simulator!

Windows Executable version of MCAP-CR Simulator with GUI is now available. Goto reference page and see bottom of the page. This is same as source package but you do not have to compile the source code. It was tested on Windows 7(64bit) and Windows XP(32bit). Source code was compiled by 64bit machine, but MinGW and Qt SDK was 32bit version, so that executable works with both 64bit and 32bit Windows OS. Multiple-Degree of Freedom Cavity Resonator Project
