A frozen cathedral beneath the ocean. A dark night in the city. A garden in the clouds. Atmospheres 2 turns your words into creative reverb spaces. Describe a place, a material or a feeling, then hear how it transforms your guitar, vocals, synths or any other audio. Let your imagination lead. Each prompt inspires a sonic interpretation, with room to explore spaces that could only exist in your music. MAKE A LITTLE MAGIC Type a prompt and create an atmosphere. Try something familiar, something surreal, or a combination of both. English prompts work best. LET RANDOM SURPRISE YOU Tap Random to generate a phrase and a new reverb space. Your Mix stays where you left it, so you can explore without changing your dry/wet balance. ONE KNOB, EASY TO EXPLORE Use the central Mix knob to blend your original sound with the atmosphere you've created. APP + AUv3 Use Atmospheres 2 as a standalone app for live audio input, or load its AUv3 effect in a compatible music app. Your generated sound and Mix are recalled with your host project, including when you copy the plugin to another track. The standalone app remembers your last sound. ENTIRELY OFFLINE Prompt generation and audio processing run locally on your device. No internet connection or account is required. BORN FROM DEEP WATERS 2 Built on the reverb engine behind Deep Waters 2, with water-inspired textures and a simple interface made for exploring. Atmospheres 2 is an audio effect: it processes incoming audio. For standalone live monitoring, use headphones or an audio interface. AUv3 use requires a compatible host app. For iPhone and iPad. Requires iOS/iPadOS 16 or later.
