Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.

I recently looked for acoustic IRs too and stumbled upon this huge database:

What do you do with this? is like the resonation of the body of the guitars?
These short mono waveforms are loaded into a Cabinet in the THU app, among other places, in order to add acousticness to your patch.
Yes, the idea is to take the dry signal of an electric guitar and add the resonance an acoustic guitar body would give to try to emulate an acoustic guitar.
(an IR is the "acoustic response" of a room/environment. A "natural" reverb/delay/resonance.)
Or, perhaps more commonly, applied to an acoustic guitar that has been recorded using an under saddle pickup in order to make it sound more like it’s been recorded using a mic.
