Create your own audio measurement system starting with TrueRTA software and your Windows PC. Then add a measurement microphone and USB interface and you have a full audio/acoustic test setup. Start with the free level 1 edition which provides a 1 octave spectrum analyzer, a dual trace oscilloscope and a signal generator. Level 1 never expires. Once you get to see the power of the software and how easily you become productive with it you will want to upgrade to a higher level with greater resolution. More...

Brent Butterworth writing for Sound and Vision Magazine, Jan 2011 :
 "While lots of audio measurement software applications exist for the PC, the one that seems to have captured the hearts of engineers and enthusiasts is TrueRTA, available at trueaudio.com. Most speaker engineers I know keep a copy on their computers."

Paul writes:

As an experienced electronic musician holding degrees in music and physics I have a lot of frequency analyzers at my disposal. TrueRTA is simply the best! It is feature rich and simple to use. The display is the most readable of any analyzer I have used. I always have it running when I am working on my music or recording and processing LP records.
Kudos to the True Audio team.

See What Our Customers Say About TrueRTA!

"I'm using True RTA installed on an iView CyberPC. It's a Wndows 8.1 PC on a HDMI stick. It's plugged into a powered 4 port USB hub to which the UCA202 is connected.
Everything worked first shot, no issues with either the software or hardware. In fact, the first Sweep I did showed me I had a problem with the amp being tested!
So, just this note to thank you for the great product.
Best, Jack"

"I find this quite an amazing package. To put this amount of test gear together in earlier days would have cost me tens of thousands of dollars. Very nicely designed, very user friendly, and tells me all I need to know in a quick and efficient way. I take my hat off to your designer !! - Arthur"
