HoRNet Valvola is a vacuum tube emulator designed to replicate the electric behavior of vacuum tubes and their surrounding circuits with remarkable accuracy. The plugin uses direct circuit modeling to simulate the characteristics of various vacuum tubes, capturing the unique sound qualities that tubes impart to audio signals. This technology, also utilized in other HoRNet products, delivers authentic tube warmth and dynamic response, making it a valuable tool for adding analog character to digital productions.

Valvola offers a selection of vacuum tube emulations, including classic triodes and pentodes, from the widely recognized 12AX7 preamp tube to the EL84 power tube. By using multiple instances of Valvola, users can build custom tube amplifier chains, enhancing their sound with rich, dynamic distortion. The plugin’s saturation effect is dynamic rather than static, reflecting the memory effect of real tubes, which respond differently to various frequencies and input levels, especially low-frequency peaks. Each tube model features unique frequency response characteristics, adding depth and authenticity to the sound.

Control is simplified with a single saturation knob that maintains consistent output level while introducing tube distortion, ensuring ease of use without unwanted gain changes. Valvola also incorporates intelligent oversampling up to 4x to minimize aliasing artifacts. The interface is fully resizable and hardware accelerated, utilizing vector graphics for sharp visuals on any display size. Compatible with macOS and Windows in various plugin formats, Valvola provides a powerful and user-friendly solution for musicians and producers seeking genuine tube sound in their digital audio workstations.
