Permitted Values
Set the maximum average
encoder output bitrate in kilobits
per second (kbps/s) for the
supported SILK sample rate.
40 kbps (default)
12 - 40 kbps
Specify the SILK encoder
complexity. The higher the
number the more complex the
encoding allowed.
2 (default)
0-2
0 (default) - Disable Enable
Discontinuous transmission
(DTX).
1 - Enable DTX in the SILK
encoder. Note that DTX reduces
the encoder bitrate to 0bps
during silence.
Set the SILK encoder expected
network packet loss percentage.
A non-zero setting allows less
inter-frame dependency to be
encoded into the bitstream,
resulting in increasingly larger
bitrates but with an average
bitrate less than that configured
with voice.audioProfile.SILK.*.
0 (default)
0-100
0 (default) - Disable inband
Forward Error Correction (FEC)
in the SILK encoder.
1 - Enable inband FEC in the
SILK encoder.
A non-zero value here causes
perceptually important speech
information to be sent twice:
once in the normal bitstream and
again at a lower bitrate in later
packets, resulting in an
increased bitrate.
