Licensing - Virtual Acoustics


Virtual Acoustics source code is licensed under Apache License Version 2.0.


Virtual Acoustics provides some input data necessary for auralization - like an HRTF dataset. Resources are generally licensed under the original Creative Commons Version 4.0 license or a CC derivative that may include share-alike distribution or prohibits commercial use. The individual license for each work is usually placed next to the resource file and is typically called LICENSE. Some files may also have the license embedded in the metadata, if possible.

External libraries

Virtual Acoustics makes use of third party libraries. If you are planning to create and share your VA application, you will have to pay close attention to the individual licenses of those projects. Especially GPL licensed third party software and static linking of third party libraries licensed under LGPL will require to share (at least) parts of your project. Other third party libraries, like fftw3, may be purchased to legally include it in your application. In any case, make yourself familiar with the individual license agreements.

Please respect the license agreements of every individual project you are planning to depend on. We will not be hold responsible if this concept is misused.

Binary packages

VA binary packages are usually shared under GNU General Public License as they rely on third party packages that make this necessary (like fftw3). The final license, however, is depending on the build configuration, and may be employable and shareable under less restrictive permissions.
