This app emulates the warm sound of classic vacuum tubes for your audio. It offers 23 modeled tube circuits, from subtle harmonic coloration to amplifier-inspired saturation. Advanced controls allow for deep customization of tube behavior and aging.

Pro Mode workflow update. • Smooth knob editing: turning Pro mode knobs no longer mutes audio. • Undo / Redo in Pro mode: every knob grip, preset change and tube swap is undoable. • Help mode: tap the "?" toolbar button, then tap any knob to see what it actually does. • Mod knob (Tube Age section): controls how shot noise scales with plate current. Default 0% = constant noise (classic character). New factory presets: • Master Polish: barely-there mastering pass (6H30, stiff PSU). • Low Iron: bass weight via 12BH7 current drive. • Vocal Silk: 6SL7 midrange focus for lead vocals. • Parallel Heat: 12AX7 saturation trimmed for parallel blending. • Super Clean: minimum-coloration baseline for your own dial-in. All factory presets are now noise-free by default. Polish: • Lower CPU during silence and at default ("zero-cost") settings. • Cleaner attacks after silent passages, no residual noise tail on digital zero input.
