The plugin features a vast library of impulse responses, ranging from small rooms to large concert halls, and even exotic spaces like caves and churches. The user can browse through the library and load IRs with ease, adjusting parameters like decay time, pre-delay, and wet/dry mix to tailor the sound to their needs. Altiverb 7 XL also features a powerful editing tool, allowing users to create their own custom impulse responses or modify existing ones.
