%description
iLBC (internet Low Bitrate Codec) is a 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.
