Design Guide for the Polycom SoundStructure C16, C12, C8, and SR12
A - 114
Description
This parameter enables (1) or disables (0) the noise fill algorithm in the AEC.
aec_ref
AEC Reference
Description
This parameter is used to set the AEC references for an given virtual channel. The
string argument specifies the name of the virtual channel that will be the AEC refer-
ence. The string argument must be a valid virtual channel name for a currently defined
virtual channel that is a conferencing line output (cr_line_out), sound reinforce-
ment line output (sr_line_out), or submix output (submix).
The index is used to specify the left (1) or right (2) reference channels. If neither
the left nor the right channel have references specified, then the AEC is disabled. If
only the left channel is specified, then the mono AEC algorithm is used. If both the left
and right channel are specified, then the stereo AEC algorithm is used.
If the reference's virtual channel is mono, then the corresponding physical
channel is used as the AEC reference. If the reference's virtual channel is ste-
reo, then either the left or right physical channel is used as a reference,
depending on which index is specified (1 for left, 2 for right).
If the AEC is on a stereo virtual channel, then the reference specifications apply
to both physical channels of the stereo virtual channel.
