What is an Impulse response?

http://www.youtube.com/watch?v=XzAmGtoswAE...ACD24FF2A3240E1

There is a simple explanation saying that the IR preset makes your music soundlike it was played in a real place. So the IR of the Sydney Opera House lets you hear what it's like in that building. But if you look at the FLstudio video, the freeverbtoo (or any convolution software) has a lot of settings. In this case, which setting (or combination thereof) is the true response from the advertised sites? In other words, IRs are stored in regular sound files like wav or aiff, and it tells you that you can record your own reverb, but what did you record if there are so many settings in every convolution engine?

Thanks.

Googling will surely give you a more accurate answer, but in short, it's a response (usually in the form of a WAV file), generated by recording a signal (an impulse) through specific circumstances. These circumstances can be real spaces, hardware equipment or, as in your video, a software plugin.
You can then combine this response (the WAV file) with other signals, to produce the sound of those circumstances. To do this you need specific software, like an IR (or convolution) reverb.

FreeverbToo is not convolution software, but an algorithmic reverb, and as such it's supposed to have a fair amount of settings to produce the sound you desire.
A convolution reverb will usually also have some settings to allow you to modify the sound to your liking (but of course it won't be able to modify the sound as much as an algo reverb). If you leave it at default it should sound like the original 'circumstance' of the recorded IR.
