You must be aware that although IzSound is released under a BSD-style license, some DSP units might require a library which is released under a license which has more constraints. It may also use third-party code published on a more restrictive license. Those DSP units can be disabled by the configure script before you build IzSound. The following table sums-up the licensing constraints put on the applications that use IzSound.
