Bug#675959: ITP: wnpp -- Internet Low Bitrate Codec (iLBC) library

                    Originally: the WebRTC project: http://webrtc.org

  Description     : Internet Low Bitrate Codec (iLBC) library

Free speech codec suitable for robust voice communication over
IP. The codec is designed for narrow band speech and results in a
payload bit rate of 13.33 kbit/s with an encoding frame length of 30
ms and 15.20 kbps with an encoding length of 20 ms. The iLBC codec
enables graceful speech quality degradation in the case of lost
frames, which occurs in connection with lost or delayed IP
packets. iLBC is specified by RFC 3951.

The iLBC codec from RFC 3951 is "almost free" (source code available,
not DFSG-compatible). It has thus been incorperated in a number of
programs. It has not been very popular recently, but it is still used in
various places (Asterisk, Opal, Yate).

Lately GIPS, who originally wrote the codec, was purchaced by Google.
Later on Google provided an iLBC codec (and some others) as part of the
newly released WebRTC code. That code has no licensing issues, but it
provides a different API. This project provides an API mostly compatible
with the original RFC 3951 codec.

The library will be packaged by the pkg-voip team.
