Panel too big or too small? Right-click anywhere on the panel and pick UI Zoom, from 50% to 125%.

Quick Start

Download

Download the latest release from wetvst.com or the Releases page.

The download includes all platforms in one universal bundle:

• Windows (x64)
• Linux (x86_64)
• macOS (Intel & Apple Silicon)

Installation

Windows

1. Download and extract the ZIP file
2. Copy WetReverb.vst3 to C:\Program Files\Common Files\VST3\
3. Restart your DAW and scan for plugins

Linux

1. Download and extract the ZIP file
2. Copy WetReverb.vst3 to ~/.vst3/ (create the folder if needed)

   mkdir -p ~/.vst3
   cp -r WetReverb.vst3 ~/.vst3/

3. Restart your DAW and scan for plugins

macOS

1. Download and extract the ZIP file
2. Copy WetReverb.vst3 to ~/Library/Audio/Plug-Ins/VST3/ (create the folder if needed)
3. Copy WetReverb.component to ~/Library/Audio/Plug-Ins/Components/ for Logic and GarageBand
4. Restart your DAW and scan for plugins

The plug-in is signed and notarised by Apple, so macOS opens it without a warning.

If macOS still blocks it

Older releases were not signed. If macOS says the plug-in "cannot be opened because the developer cannot be verified", remove the quarantine flag in Terminal and restart your DAW:

xattr -cr ~/Library/Audio/Plug-Ins/VST3/WetReverb.vst3
xattr -cr ~/Library/Audio/Plug-Ins/Components/WetReverb.component

Usage

1. Load the plugin in your DAW (Reaper, Cubase, Ableton Live, FL Studio, etc.)
2. Select reverb mode using the 5 buttons: Room, Plate, Hall, Cathedral, Cosmos
3. Monitor levels using the input/output LED meters
4. Resize the panel by right-clicking it and picking UI Zoom, from 50% to 125%

Reverb Modes

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

Features

• 5 reverb modes (Room, Plate, Hall, Cathedral, Cosmos) suitable for any goal including vocals and drums as well as creative effects
• Vintage digital signal path: 24kHz internal rate, 12-bit quantisation
• Stereo including slight crosstalk like original units from the era
• Real-time input/output LED metering
• Resizable panel: right-click and zoom from 50% to 125%
• 100% wet output - no dry signal in the mix

System Requirements

Platform	Requirements
Windows	Windows 10/11 (64-bit)
Linux	x86_64 Linux
macOS	macOS 11.0+ (Apple Silicon) or macOS 10.13+ (Intel)

Supported DAWs: Any DAW that supports VST3 plugins (Reaper, Cubase, Ableton Live, FL Studio, Studio One, Bitwig, etc.)

Building from Source

For developers who want to build the plugin themselves.

Prerequisites

Windows

• Visual Studio 2022 Build Tools or Community Edition
• CMake 3.15+
• Git

Linux (Ubuntu/Debian)

sudo apt-get install cmake gcc g++ libstdc++6 libx11-xcb-dev libxcb-util-dev \
    libxcb-cursor-dev libxcb-xkb-dev libxkbcommon-dev libxkbcommon-x11-dev \
    libfontconfig1-dev libcairo2-dev libgtkmm-3.0-dev libsqlite3-dev \
    libxcb-keysyms1-dev git

macOS

• Xcode Command Line Tools: xcode-select --install
• CMake 3.15+ (brew install cmake)

Build Steps

1. Clone with VST3 SDK:

   git clone https://github.com/yonie/WetReverb.git
   cd WetReverb
   git clone --recursive https://github.com/steinbergmedia/vst3sdk.git

2. Build:

   • Windows: build.bat
   • Linux/macOS: chmod +x build.sh && ./build.sh

3. Install:

   • Windows: install.bat
   • Linux/macOS: chmod +x install.sh && ./install.sh

Validation

The build process automatically runs the official VST3 validator (47 tests).

Technical Details

Property	Value
Framework	VST3 SDK (Steinberg)
Language	C++17
GUI	VSTGUI4
Supported Sample Rates	22.05 kHz - 384 kHz
Internal Sample Rate	24 kHz
Internal Bit Depth	12-bit with TPDF dither
CPU Usage	<1% typical
Memory	~300 KB

Audio Processing Chain

1. Anti-alias filter (10kHz LPF at host rate)
2. Downsample to 24kHz (linear interpolation)
3. Pre-delay (mode-dependent: 0-65ms)
4. Early reflections (multitapped delay line, program-dependent)
5. Parallel comb filters with internal damping (4-12 combs)
6. Series allpass filters for diffusion (4 allpasses)
7. Mix early reflections + late reverb
8. Output low-pass filter (6kHz)
9. High-pass filter (80Hz)
10. 12-bit quantization with TPDF dither and gain-stepping
11. Upsample to host rate
12. Reconstruction filter (10kHz LPF)

Troubleshooting

Plugin Not Appearing in DAW

• Restart your DAW after installation
• Check the correct VST3 folder location
• Run a plugin rescan in your DAW settings

macOS "Apple Could Not Verify" Warning

• Only older, unsigned releases do this - see "If macOS still blocks it" above

No Sound Output

• Verify the plugin is receiving audio input (check meters)
• Make sure track routing goes through the plugin
