Free sweep analysis?

[JW]

Hey folks,

I did some sine sweeps of some of my gear. It was a 15 second sweep, 20Hz to 20K, but I don't really know from the resulting waveform what I'm looking at. I see the rolloffs at the high and low end, but I can't tell exactly where they start. Just estimating from listening.

Is there some sort of sweep analysis program that's free that will do that simple task for me?

RMAA comes to mind.

Saw they have a new version, I guess at least the earlier ones are still free, as before.

Bye

Room EQ Wizard can do sweep analysis of either rooms (for acoustic treatment purposes) or equipment (for response analysis).

I use HOLM Impulse, works nice and easy.
