ThermVoltGe

Germanium Distortion AUv3

Free · In‑App Purchases

Responsive germanium distortion for standalone and AUv3 workflows. Try the complete processor for 10 active minutes, then unlock unlimited use with one purchase. ThermVoltGe is a character-focused germanium distortion processor for iPhone and iPad. Use it as a standalone audio app or insert the included AUv3 effect in a compatible host such as GarageBand. Its nonlinear core is built around an OA91-style germanium-diode architecture. A low forward-voltage threshold, asymmetric conduction, temperature dependency, battery sag, and supply-voltage interaction create early compression and a soft, rounded clipping response. FEATURES - OA91-style germanium diode clipping - Temperature-dependent nonlinear response - Battery sag and supply-voltage control - Instrument and line input modes - Boost stage - Adjustable gain, high-pass filter, tone, drive, and output - 2x and 4x oversampling modes - Standalone iOS/iPadOS app - AUv3 audio effect for compatible hosts TRY BEFORE UNLOCKING The app provides 10 minutes of full-featured active use. Demo time advances only while the standalone app or AUv3 effect is actively being used. After the allowance is used, audio processing is disabled for 24 hours. A one-time, non-consumable In-App Purchase unlocks unlimited use in both the standalone app and AUv3 extension. Restore Purchases is available in the standalone app. Customers whose verified original app version is 1.0.2 or earlier retain full access automatically without an additional purchase. ThermVoltGe is designed for guitar, bass, synthesizers, keyboards, and other sources that benefit from compressed, harmonically rich germanium drive.
