Reverb effect using hybrid impulse convolution

Build Status

Original author: Christian Borß
Current maintainer: Jean Pierre Cimalando
Contributor: Olivier Humbert

The goal of this project is to keep the HybridReverb2 project maintained and fix the issues.
The original 2009 page is archived and the research paper is available A VST Reverberation Effect Plugin Based on Synthetic Room Impulse Responses.


(quoted from the original project page)

HybridReverb2 is a convolution-based reverberation effect which combines the superior sound quality of a convolution reverb with the tuning capability of a feedback delay network. The sound quality of a convolution reverb depends on the quality of the used room impulse responses. HybridReverb2 comes with a set of room impulse responses which were synthesized with tinyAVE, an auralization software which was developed at the Institute of Communication Acoustics, Ruhr-Universität Bochum (Borß and Martin, 2009; Borß, 2009a). These room impulse responses are designed for a speaker setup with two front and two rear speakers (Borß, 2009b). For a full surround sound effect, you will need two plugins, one plugin which uses a "front" preset for the front channels and a second plugin which uses the corresponding "rear" preset for the rear channels.

A CMake build file is provided to Linux users for the ability to build LV2 and cross-compile.
The traditional Juce build process has build files for all platforms in the Builds folder. It supports all formats except LV2.

To perform a CMake-based build:

git submodule init
git submodule update
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
cmake --build .
Build option Description
-DHybridReverb2_VST2=ON/OFF Build a VST2 plugin
-DHybridReverb2_LV2=ON/OFF Build a LV2 plugin
-DHybridReverb2_Standalone=ON/OFF Build a standalone program
-DHybridReverb2_AdvancedJackStandalone=ON/OFF Build a standalone for Jack with better features
-DHybridReverb2_UseLocalDatabase=ON/OFF Use a preinstalled RIR database in PREFIX/share/HybridReverb2
-DHybridReverb2_Assertions=ON/OFF Force building with assertions regardless of build type
