With the røde podcaster the sound should be better than you are getting ... http://www.youtube.com/watch?v=cE-O7mY7nSE#t=2m40s

Possibly you could accidentally be recording the computer's built-in microphone along with (or instead of) the røde microphone ?.

The computer's built-in microphone is not high-quality (not broadcast-quality) like the røde podcaster.

Only enable the USB recording device (the røde), disable the other recording devices, (e.g. disable the built-in microphone) ...

"Something" is going wrong because a røde podcaster should sound much better than that. It "sounds" like you are about 50 cm from the mic or more.

What settings do you have in the Device Toolbar?

Can you take the equipment outside? Just for a test if you have a quiet neighborhood, test the system exactly as you have it, but without the room. Most of the presentation sounds OK, but you have that constricting echo sound and I think that's what's killing you.

I've been known to build a studio out of furniture moving blankets to get away from this effect.

You can build a tiny cave with acoustic foam, but the microphone is still going to record the wall behind you.

I know people who record in a clothes closet lined with quilts to get a "studio." Echo is a pretty serious problem and as above, there's no software solution.

There is a tool in audacity that allows one to see the reverberation. In the Analyze menu pick plot spectrum. Use the autocorrelation function. The peaks occur at the reverberation frequencies of which there are several sets probably corresponding to the walls and ceiling in the room as reflectors. Trebor's procedure can be seen to greatly reduce the reverb as the ear also agrees with.

The second recording does not show as great a reduction in reverb as the original poster's recording does with Trebor's settings. The room for this recording may not have parallel walls or for some other reason show such well defined peaks as the original poster's room. It may also be that much of the spectral content of the woman speaker's voice is so much higher than the reverberation frequency that the reverberation is less pronounced in the autocorrelation.
