Frostbite 2: Spectral Freeze and Multi-Effect Plugin by AudioThing Free Download

The freeze module is the core of Frostbite 2. The spectral mode uses FFT to store several analysis windows in memory and replays them with randomized phases, which suits pads and soundscapes built from a source sound. The reverb mode is a classic reverb algorithm built from multiple comb and all-pass filters, and it can be set to an infinite decay, so a sound can be held indefinitely as a frozen space. The convolution mode multiplies the input with a randomly generated noise impulse of up to 60 seconds, producing a different character again.

Because all three modes can be applied to any source, the same plugin can cover drones, washes and tail-based effects without switching tools.

Frostbite 2 offers two signal-flow modes. In serial mode, the modules can be reordered with drag and drop, which changes how the freeze, ring modulator and feedback stages interact. Parallel mode gives a different balance between the paths.

The internal LFO can be routed to multiple destinations across the modules, allowing slow, evolving movement in eerie or unstable textures. For more extreme results, the ring modulator and feedback can be combined with aggressive modulation to reshape a source well beyond its original character. A preset system with a randomizer, and a library of more than 70 presets, gives a starting point for exploring these settings.
