software for measurement?
 
I have just ordered, and recieved, a couple of new tools for my speaker projects. I have a Behringer ECM8000 high precision microphone and a Behringer X1222USB mixer. The mixer is a definite overkill but I have a work project that needs its capabilities anyway. It has phantom power to power the mic.

What I am needing is a recommendation for software to help set up and test speakers. Can anyone make a recommendation?

Thanks!

You should use the search function. Look for ARTA and HOLMImpulse, among others.
There are tons of posts.

Wow....I see that!

Thanks

I liked HolmImpulse a lot, but lately I've been using REW. I like the workflow better for speaker measurements where comparisons are involved. It also does tons of things I haven't explored yet, like T/S measurements.

I also like holmimpulse. I've used REW for in room measurements (using the RTA) and it is very good for that. I've also used it for T/S measurements and it is great for that as well (gave me much better results on the latest speakers that I purchased than my previous choice speaker-workshop).

Thanks for the info.

Is there a consensus for measuring frequency response that one is better than the other? I have looked at both and they both "look" good.

My objective will be to validate/tweak crossover design and calibrate active crossover points

ARTA has a very robust RTA mode that comes in handy for this sort of thing. You should always be using more precise measurements (gated impulse, etc.) in the end (which ARTA is very good for), but the RTA is great for tweaking things live, getting rough ideas of polar response, etc.

ARTA for me. Makes nice sonograms :)

They both produce the same graphs. I prefer REW just because you can deal with more than three curves at once in the "Overlays" window, and turn them on and off to simply the display. This comes in handy for making comparisons, and pulling up older things you did to see if things are really improving. ;)

Does either produce a test signal to input into the test subject, thereby a source to measure?
