What program to graph/plot a subs freq response? (1 Viewer)

I was wondering what program you guys use to graph your subs freq response. I am talking about charts like the ones seen in this post http://www.hsuresearch.com/forum/showthread.php?t=1464
Thanks.

Matt,

Try ETF (you can Google it -- I can't post URLs yet). The free demo can do a pretty good job of graphing low frequency response, using a 5 second noise burst or frequency sweep. Saves a lot of time vs. playing individual tones and marking down SPL meter measurements.

Check it out!

Matt,

As Jason Dalton posted, http://pwp.t-3.cc/ttriff/subtestmodel.xls is the best and easiest solution if you have Excel. When you enter your SPL readings for the RS meter in the "RAW SPL" field, the other field "SPL (comp)" and the graph showing the FR curve automatically update with the RS correction values! It even adds a second set of fields to enter data if you are using a PEQ , as well as giving you another line on the graph to represent the FR when using the PEQ. Allowing you to compare your FR before PEQ correction and after!



Best Regards,
Patrick

Cool, I have Excel so I will give that a try, only problem is I already corrected all my values so I will just need to revert them back to the “raw” reading. Thanks.
