HADES

Binaural rendering solutions for Hearing-Assistive/Augmented-reality Devices (HADES) is an open-source repository of both MATLAB and C implementations of the proposed and tested algorithms described in:

• Fernandez, J., McCormack, L., Hyvärinen, P., Politis, A., and Pulkki V. 2022. Enhancing binaural rendering of head-worn microphone arrays through the use of adaptive spatial covariance matching, The Journal of the Acoustical Society of America 151(4), 2624-2635

MATLAB code

The MATLAB code may be found in the matlab folder.

C code

The algorithms have also been implemented in C using the Spatial_Audio_Framework.

VST audio plug-in

The C code has also been wrapped into a VST audio plug-in using the JUCE framework:

Pre-built plug-in

The hades_renderer.vst plug-in is included in the SPARTA installer, which can be downloaded from here.

Building the plug-in yourself

First clone the repository (including submodules) with:

git clone --recursive https://github.com/jananifernandez/HADES
# or if you have already cloned the repository, update/init with:
git submodule update --init --recursive

Prerequisites

The VST2_SDK should be placed in the 'SDKs' folder like so:

SDKs/VST2_SDK

By default, MacOSX, Linux and Windows (x86_64/amd64) users need to install Intel oneAPI (MKL and IPP) and run the install-safmkl.sh/.bat and install-safipp.sh/.bat scripts found in SDKs/Spatial_Audio_Framework/scripts. Whereas, Raspberry Pi (ARM) users instead require OpenBLAS and LAPACKE libraries:

sudo apt-get install liblapack3 liblapack-dev libopenblas-base libopenblas-dev liblapacke-dev

Note, however, that alternative performance libraries may also be used, with more information provided here.

Linux (x86_64/amd64 and ARM) users must also install the following libraries required by JUCE:

sudo apt-get install x11proto-xinerama-dev libwebkit2gtk-4.0-dev libgtk-3-dev x11proto-xext-dev libcurl4-openssl-dev libasound2-dev

Building the plug-in via CMake

The plug-in may be built with CMake (version 3.15 or higher):

mkdir build
cmake -S . -B build -DSAF_ENABLE_SOFA_READER_MODULE=1 -DSAF_ENABLE_HADES_MODULE=1
cd build
make

Or for Visual Studio users (using x64 Native Tools Command Prompt as administrator):

cmake -S . -B build -G "Visual Studio 15 Win64" -DSAF_ENABLE_SOFA_READER_MODULE=1 -DSAF_ENABLE_HADES_MODULE=1
cd build
msbuild ALL_BUILD.vcxproj /p:Configuration=Release /m
