With IR captures made with microphones in real spaces, you “excite” the space with some kind of brief loud noise burst. Like playback through a speaker, a burst balloon, hand clap, etc.
It’s not uncommon, especially when hobbyists make their own IRs, that you find the noise burst still present in the sample. This produces an oddly colored version of your dry signal, in addition to the actual reverberation. In those cases I always truncate the noise burst off.
Clearly there are cases where you want to keep it, like a guitar cab in a live space.
The nice thing about IRs is that they are usually regular WAV samples - you can tinker and experiment with them as much as you want.
