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.
