Why does macOS block this plugin?
When you try to load the plugin, macOS may show: "WetReverb.vst3" cannot be opened because the developer cannot be verified.
This does not mean the plugin is unsafe. Apple requires developers to enroll in the Apple Developer Program ($99/year) and notarize each build. As an independent developer releasing free, open-source software under the MIT license, I don't have the budget for Apple's developer program. The complete source code is available on GitHub for anyone to inspect and build themselves.
This is a common issue with free audio plugins on macOS.
- Load the plugin in your DAW (Reaper, Cubase, Ableton Live, FL Studio, etc.)
- Select reverb mode using the 5 buttons: Room, Plate, Hall, Cathedral, Cosmos
- Monitor levels using the input/output LED meters
| Mode | Comb Filters | Pre-delay | Early Refl. | Character |
|---|---|---|---|---|
| Room | 4 | 17ms | 3-24ms (6 taps) | Intimate, prominent reflections |
| Plate | 8 | 0ms | 2-17ms (5 taps) | Dense shimmer |
| Hall | 10 | 25ms | 8-53ms (7 taps) | Spacious, smooth |
| Cathedral | 10 | 37ms | 12-79ms (8 taps) | Long, diffuse |
| Cosmos | 12 | 65ms | 15-92ms (6 taps) | Ethereal, infinite wash |
Pure reverb signal output - no dry signal in the mix. Perfect for:
- Parallel processing with dry signal in your DAW
- Creative sound design
- Authentic vintage rack reverb simulation
- 24 kHz Internal Sample Rate - Authentic vintage digital reverb with band-limited frequency response
- 12-bit Quantization - Classic gritty digital character
- TPDF Dither - Smooth quantization
- Stereo Crosstalk - Authentic L/R channel bleed simulating analog circuitry
- Early Reflections - Program-dependent multitapped delay lines for realistic room ambience
- HF Damping - Mode-dependent high-frequency rolloff
Parallel comb filters with damping followed by series allpass diffusion.
Full parameter automation support in all major DAWs.
