The Cinematic Atmosphere Toolkit offers an extensive collection of instrument samples, atmospheres, and sound design elements tailored for cinematic music production. This sample library is integrated into FrozenPlain's Mirage, a sample-based synthesizer that provides intuitive control and easy access to all sounds, making it ideal for composers and sound designers seeking inspiration and flexibility.

Designed to enhance horror scores and atmospheric compositions, the toolkit features sounds perfect for jump scares, eerie textures, and ominous moods. It also enables creators to build otherworldly soundscapes, dystopian backdrops, and sci-fi action effects. Developed in collaboration with sound designer Glitchedtones, this collection focuses on immersive and evocative sonic environments suitable for film, games, and multimedia projects.

The package includes six sample libraries with a total of 788 samples, all playable as oscillators within Mirage. Users gain access to 300 presets organized for quick browsing and spontaneous creativity. Mirage's advanced features, such as a three-layer architecture, envelopes, filters, looping options, and a comprehensive effects rack, provide deep sound shaping capabilities, enabling the creation of unique and dynamic atmospheric sounds.
