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.
