| 1 spandsp 0.0.5 - A DSP library for telephony | |
| 2 ------------------------------------------- | |
| 3 | |
| 4 SpanDSP is a library of DSP functions for telephony, in the 8000 sample per | |
| 5 second world of E1s, T1s, and higher order PCM channels. It contains low level | |
| 6 functions, such as basic filters. It also contains higher level functions, such | |
| 7 as cadenced supervisory tone detection, and a complete software FAX machine. | |
| 8 The software has been designed to avoid intellectual property issues, using | |
| 9 mature techniques where all relevant patents have expired. See the file | |
| 10 DueDiligence for important information about these intellectual property issues. | |
| 11 | |
| 12 The library is licenced under the LGPL 2.1 licence. The test suite, and some support | |
| 13 programs are licenced under the GPL 2 licence. The full text of these licences can | |
| 14 be found in the file COPYING. | |
| 15 | |
| 16 Dependencies | |
| 17 ------------ | |
| 18 | |
| 19 spandsp depends on various other packages for various tasks. Most of these | |
| 20 dependencies relate to building the test suite. | |
| 21 | |
| 22 libtiff (and libtiff-devel on most Linux distributions) is required to | |
| 23 build the spandsp library. | |
| 24 | |
| 25 libaudiofile (and libaudiofile-devel) is required to build the test suite | |
| 26 fftw (and fftw-devel) is required to build the test suite. Version 2 or 3 of | |
| 27 FFTW may be used. Spandsp adapts to the differences between them. | |
| 28 | |
| 29 fltk (and fltk-devel), Fl_Cartesian and Fl_Audio_Meter are required to build | |
| 30 the test suite with GUI interfaces for some of the tests. The tests will build | |
| 31 without these packages, but the GUI features will not be available. | |
| 32 Fl_Cartesian and Fl_Audio_Meter can be downloaded from | |
| 33 http://www.soft-switch.org/downloads. | |
