Image caption: More points equal far greater detail and realism than any other hardware IR device. Impulse responses allow the sound and character of a mic’d speaker cabinet to be captured, so that any audio signal can be processed by the resulting impulse response and sound as if it’s being played through that exact speaker cabinet. Iridium is able to deliver impulse response resolution far greater than any other piece of outboard gear. With full 24bit 96kHz resolution for the entire 500 milliseconds of its speaker cabinet impulse responses, Iridium is able to use the absolute highest quality IRs available. This means countless details are accurately preserved and reproduced to give you a completely real speaker response. Every cabinet resonance, speaker vibration, as well as reflections between the cabinet, the mic, the floor, and the ceiling; all the minuscule cues that tell our brain we are listening to our favorite cabinet are preserved, providing completely lifelike realism.
