Impulse Response [IRs]

An Impulse Response (IR) is a very short audio recording that captures how a space or piece of gear (like a room, cabinet, reverb unit, etc.) reacts to an impulse sound (such as a sharp click or sweep tone). This recording is then used to accurately recreate the sonic character of that space or equipment using convolution plugins. IRs are widely used in convolution reverbs, but also to simulate guitar amps, speaker cabinets, and even vintage hardware.
