- Signal flow manipulation (series vs. parallel)
- LFE toggle
- Bit depth manipulation
- Dithering
- FX mix control
- Downsampling factor
- Interpolation
- FX mix control
- Gain reduction
- FX mix control
Pre-made bundles are available, but only for some versions of Wwise. If a bundle is not available for your target version, you can package one yourself—but be sure to check the Releases page first.
If your bundle is compressed (e.g., a ZIP file), extract it first. Then open the Wwise Launcher, select the Plug-ins tab, and click Add from directory. Select the extracted folder, and the plugin should begin installing. Once complete, you can open Wwise and start using OhFi. For more details, see the official docs by Audiokinetic.
If you’re using OhFi in a project (e.g., Unreal, Unity, etc.), you’ll need to add the plugin to your project like any other Wwise plugin. For Unreal and Unity, this process can be automated via the Wwise Launcher.
If a pre-made bundle is not available for your target Wwise version, you can create one yourself. This process requires at least a Windows machine with Python 3 installed, but you may also need access to other systems (e.g., macOS) depending on your platform targets.
At the root of the repository, you’ll find a script called build.bat. On Windows, assuming you have Visual Studio 2022 and C++ dependencies installed, run build.bat to:
- Generate Visual Studio solutions and projects
- Compile and link the C++ code
- Package all necessary files
Then, run bundle.bat to create a new bundle. Once complete, you’ll see a Bundle folder in the repo root containing everything needed to install OhFi.
To build for macOS, run build.sh on a macOS machine or virtual machine. This script mirrors build.bat but is adapted for macOS. Similarly, bundle.sh is equivalent to bundle.bat. For other platforms, refer to the Audiokinetic documentation.
Note: Whenever prompted from a Wwise/plugin version, user the format year.major.minor.build (e.g., 2024.1.4.2). The section build can be any number (up to 4 digits).
