Howdy!

I am trying to set my TiDEQ now that it is installed and I need a free RTA program to run on my laptop. Any suggestions or ideas?

Big thanks,

I did find a free half octave IIRC RTA program, but the Mics were not free, though they did show ways to use cheaper mics, I woud imagine the accuracy to not be close enough.

If I find teh link again, I'll post.

Given that I have been out of my last corp job since Feb and I am trying to start my own company, money is a little "tight". Thus my search for a free RTA. If I had the money I would buy TrueRTA at 1/3 octave.

I hate to bump my own post but I have scoured the web looking for a free RTA to setup my system, but to no avail. Is there anyone here on the forum with any information?

Thanks,

Erinn,

Thanks for the input. I had previously attempted to use this one but I don't seem to be able to find a way to keep it graphing the audio, only in short "test" burst that then graph the data. Additionally there does not seem to be a bar graph 1/3 octave option.

Perhaps I am overlooking it? I am sure I don't know how to use this program correctly. Any information you or some else can offer would be of great benefit.

Thanks,

Generally an RTA will send a known signal of a specific length (a burst) to the stereo and then "listen" to what it actually plays with a highly sensitive mic.

The software then graphs the response as it "hears" it through the mic on a frequency/time plot.

You then can go a head and adjust your EQ to compensate where you need to and run the test again. Compare differences.

Something like that.

I have no idea how to use the software I uploaded. I tried it once, to no avail.

You may want to see if you can locate a "spectrum analysis" software and set it to your mic input and use a calibrated mic. I know some programs such as media player have spectrum analyzers built in, and you may be able to take advantage of this.
