# Installation

> Install ANTIVERB as VST3 or Audio Unit on macOS, or as VST3 and a standalone application on Windows

# Installation

## System Requirements

* **OS:** macOS 13.0 or later (Apple Silicon and Intel); Windows 10 or later (64-bit)
* **Formats:** VST3 and Audio Unit (AU effect) on macOS; VST3 and a standalone application on Windows
* **Channels:** stereo or multichannel input (up to 8 channels are placed), 2 to 16 output channels
* **Host:** any VST3 or AU host

In the host's plug-in list ANTIVERB appears as **ANTIVERB** by **NOMN**, under Fx / Reverb.

## Download

Download the latest ANTIVERB disk image (macOS) or .zip archive (Windows) from [nomn.jp](https://nomn.jp).

## Install

### macOS

The disk image is signed and notarized. It holds the two plug-in bundles and an install script, `install.sh`.

1. Open the disk image.
2. Run `install.sh` from Terminal (drag it onto a Terminal window and press Return). It copies both bundles into your user plug-in folders, creates the preset folder and clears the Audio Unit cache.
3. Restart your host.

To install by hand, drag the two bundles into these folders:

| Format | Location |
| - | - |
| **VST3** | `~/Library/Audio/Plug-Ins/VST3/ANTIVERB.vst3` |
| **AU** | `~/Library/Audio/Plug-Ins/Components/ANTIVERB.component` |

Both locations are in your user Library, so the plug-in is installed for your macOS account only.

### Windows

Extract the .zip archive and copy `ANTIVERB.vst3` to `C:\Program Files\Common Files\VST3\`, then restart the host or rescan its plug-ins. `ANTIVERB.exe` is the standalone application and runs from any folder; choose its audio device from its **Options** button.

## Stereo and Multichannel Tracks

On a stereo output ANTIVERB runs as a stereo processor and the SPATIAL tab has no audible effect.

On a multichannel output (quad, 5.1, 7.1, 7.1.4, 9.1.6 and so on) ANTIVERB reads the host's channel count and renders to that many outputs, up to 16. Set the track or bus to the channel format you want before inserting the plug-in (in Reaper, set the track channel count first). The first time an instance meets a channel count it seeds a speaker layout for it. Choose the layout that matches the room on the SPATIAL tab. See [Speaker Layout](/antiverb/interface/speaker-layout).

## Uninstall

Delete the two bundles listed above (on Windows, `ANTIVERB.vst3` and `ANTIVERB.exe`). User presets live in `~/Library/NOMN/ANTIVERB/Presets/` on macOS and `%APPDATA%\NOMN\ANTIVERB\Presets\` on Windows; delete that folder to remove them as well.
