Real time analyzer

After reading Jim Smith's Get Better Sound I am considering purchasing a real time analyzer that can measure on at least a 1/3 octave scale. I would like to spend less than $400. I have seen several PC based systems that fall within my price range. Also, the Samson D-1500 falls within my price range. I would appreciate your guidance and recommendations on this topic.

The simplest RTA is TrueRTA (freeware for low res but inexpensive)which comes in various resolution levels up to 1/24 octave.

Next up is RoomEQWizard (freeware) which does RTA as well as many other equally important functions.

Both of these require you to add a microphone which can range from the Radio Shack SLM or Behringer+mic preamp.

There is a nice package of software+hardware, that will do RTA plus other useful functions, called xtz.

All of these can be implemented for under $400. There are, undoubtedly, others but I have used all of these.


Also, there is R&D
Behringer DEQ2496.
Second the DEQ2496, for an inexpensive RTA(1/6 oct): ( Often found on eBay too: ( The Mic is extra, if bought new, BTW.
Anybody know of software that works with phase/delay? Aside from DEQX and Holm.
Thank you for your kind responses. Looks like the DEQ2496 is far more than just an RTA. Presumably, I can use the tuned microphone from my Velodyne DD12 with the DEQ. Thanks again for your assistance.
R+D, TEF work with phase/delay, depending on what you mean.

If you have an android phone, there is a free app to do this. Its not as accurate of course, but its free, and you can get an idea of where your room is.

Thanks Kal

Didn't find R&D
TEF looks very competent but, being hardware based, is also expensive.
Led me to Smaart v7, ($895) which is closer to what I imagined.

Generally, it's not the software, but the quality of the microphone that can introduce variables.

Ideally, the mic could be a condenser omni, calibrated to the system.

Never a dynamic cardiod, as is found in the Radio Shack meters.
I know this response is a little late but I use a Behringer Ultracurve Pro (under $300) and a calibrated mic ($50 from your local Guitar Center). I use this unit for speaker building measurments, Audio system setup, PA system control when I gig, recording, and final mixdowns. Incredibly flexible piece of gear.
