Hollow

Hollow stands as a sophisticated reverb plugin built on a 16x16 feedback delay network architecture. The engine comprises 24 delay lines and 32 filters arranged in a densely interconnected matrix capable of generating 256 feedback paths, enabling decay times exceeding 15 minutes while maintaining natural exponential behavior. This density of processing distinguishes Hollow from algorithmic reverbs that prioritize computational efficiency over spatial complexity.

The plugin's dual-direction pre-delay warrants particular attention. Beyond standard operation, it can position the reverb tail before the dry signal, creating disorienting yet musically viable textures useful for experimental production. A variable diffusion stage shapes how quickly reflections scatter, while adjustable low-pass or high-pass damping filters control high-frequency absorption - essential parameters for managing tail character across musical contexts.

Four phase-shifted sine oscillators provide unison-style modulation that adds subtle movement and chorus-like richness to reverb tails. The stereo width control extends from mono collapse to expansive separation, affecting the perceived dimensionality of the reverb field. Notably, all continuous parameters feature lag filtering, eliminating artifacts during real-time automation.

Hollow serves producers seeking lush, characterful reverb spaces rather than clinical algorithmic clarity. The plugin excels in electronic, ambient, and experimental music where extended decay times and sculptural tail manipulation are assets. While CPU-intensive at maximum settings, it offers scalable complexity through parameter reduction. Among contemporary algorithmic reverbs, Hollow prioritizes sonic depth and creative flexibility over simplicity, positioning itself alongside tools like Valhalla Room rather than basic convolution alternatives. Professional sound design and mixing work benefit most from its capabilities.
