Software and APIs
Thus, SOFA files can be loaded and edited in the HDFView. This is a generic viewer; it allows to browse through all metadata and data in a numeric format only.
API: SOFA API for Matlab/Octave
SOFA API for Matlab/Octave aims at providing a basic interface for handling SOFA files in Matlab and Octave.
API: SOFA API for C++
An API for C++ is available online. The version 1.0 is in accordance with the AES69-2015 standard.
The sources are stored at github.

API: SOFA API for Python
pySOFA is a SOFA API for Python made by Jörg Encke (TUM, Munich). The API is currently read-only and implements the FIR Datatype. It was implemented for a specific project and only implements a limited amount of features. If you have question about this API, feel free to contact Jörg Encke or to submit an issue report.
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).
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.
WaveCloud-M is Matlab-oriented room simulator. Beginning with version 1.0, WaveCloud-M can use HRTFs saved in SOFA to render binaural signals.
Application: SOFAlizer plug-in for VLC player
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. Details on the installation can be found here.
DirPat is a set of tools aiming at the analysis and visualization of the directivity of acoustic sources like loudspeakers, microphones, singers, talkers, and music instruments. DirPat consists of user interfaces, signal-processing tools, and a database of measured directivities which are handled as SOFA files.
