What Hollow does
The core of the plugin is a delay network made of 24 delay lines and 32 filters, with feedback routed between them. With every setting at its maximum, the developer states the engine can produce tail times longer than 15 minutes. The algorithm adds a trademark unison modulation, carried by four phase-shifted sine oscillators, which the developer describes as adding depth and movement to the tail.
Finely tuned low-pass and high-pass damping filters shape how the reverb decays across the frequency range. Hollow is offered as VST3, AU and AAX, and it loads on Windows and macOS.
Key features
- Delay network. A network of 24 delay lines and 32 filters, with feedback between them, forms the reverb core.
- Extended tails. With all settings at their maximum, the developer states tail times can exceed 15 minutes.
- Unison modulation. Four phase-shifted sine oscillators apply a unison modulation that the developer names as a trademark of the plugin.
- Damping filters. Low-pass and high-pass damping filters are tuned to control the decay of the reverb.
- Crack, keygen and serial variants. Search queries often pair Hollow with keygen, serial key and crack, and the repack is commonly shared as a .rar.
