Licensing

The Rubber Band Library is available in two editions:

• The Free Software edition is available for download from this site (see here) and is provided to you under the GNU General Public License, version 2 or later. You get the source code and the right to modify and redistribute it, provided that you do so in a work that is similarly licensed with source code under the GPL.
  The Free Software edition uses FFTW and libsamplerate to do Fourier transforms and resampling; these libraries are also published under the GPL.
• The commercial edition is available for use in proprietary software applications. The standard licence is extremely flexible, and a budget independent-developer licence is also available for individuals working on low-cost applications.
  With the commercial edition you also obtain the source code with the right to modify it if you desire, along with 12 months of updates. Optionally at a small extra cost we can provide ready-to-use binary libraries for Win32 and OS/X.

The commercial edition contains essentially the same source code as the Free Software edition, but provides more flexibility in build environment and library support. It includes support for Visual C++ on Windows, and for Intel Integrated Performance Primitives and Apple Accelerate/vDSP frameworks as alternatives to FFTW and libsamplerate (though you can also use these if you have commercial licenses for them).
