spandsp - A DSP library for telephony
|
|
-----------------------------------------------
|
|
|
|
SpanDSP is a library of DSP functions for telephony, in the 8000 sample per
|
|
second world of E1s, T1s, and higher order PCM channels. 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.

The library is licenced under the LGPL 2.1 licence. The test suite, and some support
|
|
programs are licenced under the GPL 2 licence. The full text of these licences can
