Q: what are Impulse Responses?
-
Nov 18, 2010 6:32 PMby 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.

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.
