Windows VST3 • Built with JUCE • Senior design thesis project
What is Hemlock Cloak?
Hemlock Cloak is based on the Harmony Cloak research from the University of Tennessee. It adds carefully designed, psychoacoustically masked perturbations to your audio that are inaudible to listeners but make the signal difficult to use for training AI models.
Key Features
Inaudible Protection
Psychoacoustic masking and frequency-domain processing keep the effect transparent while adding adversarial noise under the hood.
Export-Only Watermarking
The watermark is only applied during offline bounces/exports, keeping live playback clean and CPU usage low.
Simple Controls
An on/off toggle and intensity control make it easy to dial in the amount of protection you want.
