SOFAlizer: Demo of a SOFA-based audio engine in C++

SOFAlizer is a simple demo of an audio engine as a plugin for the VLC-Player.

Currently, Windows binaries of the VLC-Player 2.1 compiled with the SOFAlizer plugin are available. In order to use SOFAlizer:

  • Download the official VLC 2.1 from here and install on your machine
  • Download the SOFAlizer from here, unzip, and copy over your VLC installation
  • Start VLC
  • Goto Tools, Preferences, check "Show settings: All"
  • In the left panel, for Audio/Filters, check "SOFAlizer"
  • In the left panel, for Audio/Filters/SOFAlizer, select at SOFA file 1,2,3 up to three SOFA files
  • Click on Save
  • Goto Tools/Effects and Filters, in that panel, select "SOFAlizer"
  • Enable SOFAlizer
  • Load a audio/video file, enjoy

The source code is available here. The file sofalizer.c can serve as an example of how to load SOFA files in C++.

WaveCloud-M

WaveCloud-M is Matlab-oriented room simulator. Beginning with version 1.0, WaveCloud-M can use HRTFs saved in SOFA to render binaural signals.

Spat

Spat is a software suite for spatialization of sound signals in real-time intended for musical creation, postproduction, and live performances made by IRCAM. It supports SOFA for binaural rendering.

HDF5View

SOFA files are based on netCDF-4. NetCDF is based on HDF5. HDFView is a generic viewer for HDF5 files running in Java.

Thus, SOFA files can be loaded and edited in the HDFView.

libmysofa

Libmysofa is a light weight C-library intended to read SOFA files for spatial rendering.

It hardly has any library dependencies and is suitable for embedded devices. It can read SOFA files and check whether the data comply the "SimpleFreeFieldHRIR" conventions. In addition, provides functions to look-up and interpolate the filters for a given orientation and to normalize the HRTFs to a reference level. It compiles unter Linux (CMake) and Windows (Visual Studio 2015).
