Are there any reasonably priced/ free laptop RTA programs?

[aarond]

I'm curious about what might be available. A quick Google search shows that PE offers TrueRTA for about $40 which seems very reasonable. Anything else out there?

In the context of a speaker building forum I assume you just mean the ability to run sweeps and measure SPL at frequency - as in you're not specifically looking for only a Real Time Analyzer?

REW (does include RTA)
Holm Impulse (no RTA)
ARTA (not sure if it has RTA)

[DeZZar]

I have TrueRTA and ultimately never use it.....REW does pretty much everything you'll need.

Holm can be set to noise output, and only amplitude smoothing. Sort of like RTA. I use it that way sometimes just to get an idea what the room is up to, although I use the frequency dependent time-windowing a lot more often.

REW does have an RTA window.

Cool, I'll give REW a try, I've read good things about it in the past. a quick look at the page shows it'll work for what I need.

Although I did ask about an RTA, like you guys guessed my interest revolves around speaker building. My immediate need is room analysis for (hopefully) easy to tame peaks.

REW (Room EQ Wizard) is precisely what you need then
