TubeSound adds the warm, rich character of classic vacuum tubes to your audio. This is not a typical tube-style distortion effect. Many presets operate below 0.5% THD, producing subtle harmonic coloration rather than heavy saturation. REAL TUBE CIRCUITS 23 carefully modeled tube circuits inspired by legendary hi-fi and guitar amplifier designs from the 1950s to today. Each model recreates key parts of the original design, including triode curves, power supply sag, transformer behavior, and natural analog drift. PRO MODE Take full control over tube circuit behavior with advanced parameters such as plate voltage, grid bias, PSU stiffness, transformer saturation, and more. Includes 5 factory presets inspired by iconic circuits, plus the ability to save and manage your own custom Pro presets. TUBE AGING Three wear stages: New, Worn, and Old. Each stage changes the tube character with increased noise, wider drift, and reduced gain. AUv3 PLUGIN Use TubeSound as an Audio Unit effect in GarageBand, AUM, or any AUv3 host. FREE TO TRY All 23 circuits are available in the trial version. During the trial, audio mutes for 3 seconds every 30 seconds. A single in-app purchase removes this limitation.

This not only lowered the input gain to the interface enough to remove the gain distortion, but also warmed up the signal to create really nice tones during playback. A cool and simple app. ## Frequently asked questions about TubeSound ### Does TubeSound have ads? No, TubeSound does not contain advertisements.

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. ### 2.6.1 — 2026-04-30 Plugin manufacturer renamed to "TubeSound", easier to find in your DAW's effect list. ### 2.6.0 — 2026-03-23 Revised Audiophile presets with enhanced character. ### 2.5.5 — 2026-03-21 Fixed inconsistent THD measurements. ### 2.5.4 — 2026-03-18 Updated App Store visuals. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
