OPENDAFF

This is the official website of OpenDAFF, the Open Directional Audio File Format. OpenDAFF is a free and open source software package for directional audio content like directivities of sound sources (e.g. loudspeakers, musical instruments) and sound receivers (e.g. microphones, head-related transfer functions, HRIRs/HRTFs). OpenDAFF enables a simple exchange, rapid access and efficient storage of such directional content in form of a single DAFF file (*.DAFF). Under the term software package, OpenDAFF unites the DAFF file format conventions, a C++ software library for reading DAFF files, a C++ visualization library using VTK and QtWidgets and extensive Matlab scripts for writing DAFF files. The package is complemented by tools like a graphical viewer application (called DAFFViewer) and a command-line utility (called DAFFTool)... OpenDAFF has been brought into existence by the Institute of Technical Acoustics at RWTH Aachen University. Released for free under the Apache License..
