It contains low level +functions, such as basic filters. It also contains higher level functions, such +as cadenced supervisory tone detection, and a complete software FAX machine. +The software has been designed to avoid intellectual property issues, using +mature techniques where all relevant patents have expired. See the file +DueDiligence for important information about these intellectual property issues. + +Dependencies +------------ + +spandsp depends on various other packages for various tasks. Most of these +dependencies relate to building the test suite. + +libtiff (and libtiff-devel on most Linux distributions) is required to +build the spandsp library. + +libaudiofile (and libaudiofile-devel) is required to build the test suite +fftw (and fftw-devel) is required to build the test suite. Version 2 or 3 of +FFTW may be used. Spandsp adapts to the differences between them. + +fltk (and fltk-devel), Fl_Cartesian and Fl_Audio_Meter are required to build the +test suite with GUI interfaces for some of the tests. The tests will build +without these packages, but the GUI features will not be available. +Fl_Cartesian and Fl_Audio_Meter can be downloaded from +http://www.soft-switch.org/downloads. + +Steve Underwood <steveu@coppice.org>
