Nov 18, 2010 6:32 PM in response to peteratomicby Pancenter,Within the context of Logic it's data Space Designer uses to reproduce the qualities of a sampled "environment" such as a hall, room, cave.....etc. It can also be sampled data from hardware effects so that an impulse response emulates the sound of a Lexicon reverb.

Nov 18, 2010 6:33 PM in response to Pancenterby peteratomic,So what apps other than Logic use them? That's what I'm trying to figure out. (I don't have Logic.) -
Nov 18, 2010 6:40 PM in response to peteratomicby Niel,Similar programs such as Reverbrate may use items in those folders. If you don't use any music creation software, delete it. If you do, move it to the desktop for a few days and see if it's affected.

Nov 18, 2010 6:50 PM in response to Nielby peteratomic,I use Ableton Live, but I'm sure the IR files didn't come with that. Perhaps Soundtrack Pro? Thanks for the suggestion about offloading them and see what happens! -

STP, possibly, or one of the other Pro-Apps (Final Cut?)

Jan 11, 2011 11:13 AM in response to peteratomicby Lust,Besides convolution verbs...amp modelers can also take advantage of IR's.
As a guitarist when I can't record an amp with a mic...I will use a modeler.
In the modeler I will turn off the cabinet and use an IR instead because, well, it sounds better....if an app doesn't have IR loading capability like Logic Studio one can use a Plug-in such as LAConvolver.
Red Wire is a company that sells cabinet IR's....their definition for an IR is as follows.
+...an impulse response (or "IR") realistically captures the characteristics, both in frequency and time, of an entire signal chain, including the sampled speaker, the microphone, the room it's in, the power amp, preamp -- even the A/D converters. Put another way, it'll capture the unique frequency curve of the speaker, any phase smearing inherent in the mechanical operation of the speaker, any cabinet resonance, the frequency response and resonance of the mic, the sound of the room, and any frequency or phase related coloration introduced by the power amp, preamp, and converters and apply that captured sound to any audio you pass through it... or so our even geekier friends tell us.+

Audio Ease also uses IR's for it's product line...like speakerphone and cabinet...etc.
