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?

No announcement yet.
Are there any reasonably priced/ free laptop RTA programs?

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)Constructions: Dayton+SB 2-Way v1 | Dayton+SB 2-Way v2 | Fabios (SB Monitors)

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.Francis

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.
Thanks,
Aaron
