I'm looking for a website or a program that you can see crossover rolloff from points that you choose. Say I want to see rolloff of a HPF set to 2000hz @ 36db/octave. Or maybe a LPF set to 180hz @12db/octave.
If you click on this link:
http://www.bcae1.com/elecxovr.htm
and scroll down about half way to the paragraph that starts with, "Put your mouse/cursor over the crossover frequencies to the left of the graph to see how the slope slides...", the graph below that paragraph is similar to what I'm talking about but it's not specific enough and the xover points are chosen already.
It would be even better if it had the option to have the cursor follow the line and display the exact frequency it's on like in WinISD. If it doesn't have this option, then it would at least have to have the frequency log scale labeled.
If you have used one and know the link to it, I'd appreciate it if you posted it. Thanks
