Yes ,It works rather nicely.

I'm still learning the in and outs although it is extremly easy to use.

It recognizes my GINA-24 card with asio driver with no problem.
However I'm not sure if it is sampling in 24bit or not.

The scope screen only displays + and - 32000 steps on the side of the display (graticule persay).

The features are limited compared to some other programs I have tried.
But, It is adequate as it does everything you need for testing audio as well as saving any sample curves.

Not sure if it does signal generation as I use a seperate devices for that.
I haven't verified the validity of the THD measurement yet but I will as I keep working with it.

I very easily and quickly did some frequency response measurements of my room and system and was able to save them.
But, I haven't learned how to post the files as JPEG or BMP or graphs yet, as I have only used it briefly so far.

But it appears to be quite accurate compared to some past measurements with other programs that I use.

I just down loaded a new beta version of VISUAL ANALYZER today and once I got it setup and working it was much better than the previous version.
Although, It did lockup my machine up a couple of times but not like the pervious versions I had used in the past.

WaveSpectra work flawlessley and no lockups on my P4 2.8ghz machine so far.
The screen update was quite fast.

Visual Analyzer is an intense program and cpu power hungery so those with something better than my P4 may not have any issues at all, as it is still under development . jer

Hi Jer,

Yes features are limited but I amazed with it speed and accuracy.

For signal generation I use ttg.exe (Test Tone Generator from Esser Audio Research) it is also free.

Yup, for screenshots I have to use Alt+PrintScreen and Paint Brush.

To speed up screen refresh you may use DDraw3 from drop down in settings.

Your Processor is good one (P4 2.8 GHz).

With ARTA I see glitches but WaveSpectra does not show any glitches or hang-ups it runs smooth. I use it to measure THD of my designed wien oscillators.

Cool Thanks.
That saves me the headache of using my camera and its associated steps.
Now all I have to do work with it to learn how to use it which seems easy enough.
Thank again. jer

I might add there is a similar program called Room EQ Wizard...from one of those other sires.
I use it mostly for acoustic measurements. In many cases I like it better than the old TEF20.
It also interfaces with programmable equalizers....REW V5 REW - Room EQ Wizard Home Page
This program is free, but they ask for a donation. It is a stable program...with few bugs.

I have been messing around with "Room EQ Wizard" today.
I must say that it is one great program.
It has a great GUI,the layout is very nice and very easy to use as well as acurate compared to the other programs I have used so far.
Great find!
Thanks again, Dave. jer

P.S. I also got the Fast Stone viewer aswell but I haven't tried it yet as I was having to much fun with REW 5.
