Found something within winISD sub sim software

[THUMP-LUMP]

I was mucking about with winISD and for some reason, right clicked on the graph. A window pops up and among a few options, you can export data to a file. Ummmmm. This got me wondering so I did save it (it saves as a .txt file) and took a look. It looked a lot like the .frd files I have created with HolmImpulse. So I saved it as a .frd and loaded it up in PSD-Lite. Now this got interesting. I loaded just fine in PSD-Lite and now I can also see what a simmed sub will do when a low pass xover is applied to it. On my sample, I lost 2dB with a 18dB/oct xover on a sealed sub enclosure. Attached are a couple examples of what I found. On each pic, the top graph is the raw data from winISD and the lower graph is with a xover applied in PSD-Lite.

From what I understand, winISD PRO version already does this but for those that use an OS that was produced for this millennia, you will have problems with the PRO version. It was/is intended for win95/98.

Both winISD and PSD-Lite are freeware.

I was just informed about a newer version available of WinISD than what is on their website AND it works like mentioned above AND shuts down correctly in Win7/64.
