IR: Impulse response. But do you know what they are?

IR: Impulse response. But do you know what they are?

I will try with this article to explain in a simple way what IRs are.
In recent years the IR (Impulse response) have grown more and more in notoriety!
Surely the flood on the market of digital devices such as Kemper Amp, Helix, Hx Stomp, Headrush, Pod Go, Fractal, Ampero, Mooer GE and many others have led to the use of impulses to improve the sound. To improve the guitarist usually intends to “make it more realistic” and get closer to the response of an amplifier (in this case cabinet) real, true.

We can define impulse responses as the profiles of a cabinet with its speaker.
The elements that influence (or can influence) the recording of these profiles are mainly 3: microphone, cabinet / speaker type and mic preamplifier.

The process of profiling and capturing an impulse response takes place following a precise chain. A “sweep” signal (a sonic progression of all frequencies from 0 to 20,000 Hz) is sent to and out of a cabinet (with a speaker inside). This sound wave is captured by a microphone placed in front of the cabinet. The signal captured by the microphone is then processed by the pc in the studio and with a few final steps we have our custom impulse response!
