An auralisation system that takes a head-worn microphone array recordings as input and renders the audio for binaural playback; taking into account both the listener's head-orientation and relative position from the recording point.

The system is realised as a real-time VST audio plugin, which supports:

• Loading ATFs and HRTFs via the SOFA standard
• The ability to change the balance between the directional and ambient rendering streams per frequency band.

A video demonstrating the 6DoF rendering with the various approaches is available here.

Developed using JUCE and the Spatial_Audio_Framework.

Doxygen based documentation may be generated with the following command:

cd docs/doxygen
doxygen doxygen_config

This can then be viewed in your browser by opening: docs/doxygen/html/index.html

The instructions for building the plugin are the same as those for building the SPARTA plugins

The TL;DR: the plug-ins may be built with CMake (version 3.15 or higher).

MacOS: To build a universal (ARM and x86_64 compatible) version of the audio plugin and unit testing program:

mkdir build
cmake -S . -B build -DSAF_PERFORMANCE_LIB=SAF_USE_APPLE_ACCELERATE -DCMAKE_OSX_ARCHITECTURES="arm64;x86_64" 
cd build
make

Windows (x86_64):

cmake -S . -B build -G "Visual Studio 15 2017" -DCMAKE_GENERATOR_PLATFORM=x64 -DSAF_PERFORMANCE_LIB=SAF_USE_INTEL_MKL_LP64
cd build
msbuild ALL_BUILD.vcxproj /p:Configuration=Release /m

Note: Windows versions require intalling Intel's OneAPI (specifically for Intel MKL), and running the build scripts found in extern/Spatial_Audio_Framework/scripts.

Linux: (x86_64) using Intel MKL:

mkdir build
cmake -S . -B build -DSAF_PERFORMANCE_LIB=SAF_USE_INTEL_MKL_LP64
cd build
make

Note: this require intalling Intel's OneAPI (specifically for Intel MKL), and running the build scripts found in extern/Spatial_Audio_Framework/scripts.

Linux: (x86_64) using OpenBLAS:

mkdir build
cmake -S . -B build -DSAF_PERFORMANCE_LIB=SAF_USE_OPEN_BLAS_AND_LAPACKE
cd build
make

Note: this require intalling OpenBLAS and LAPACKE with e.g.:

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