spandsp 0.0.1 - 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.
