3.4.1 Audio Conferencing API for Linux and Windows Operating
Systems Library Reference
Update to dcb_getbrdparm( ) and dcb_setbrdparm( ) functions (IPY00006584 = PTR
36199)
Changed the description of the MSG_ACTID parameter to indicate that it
enables/disables active talker identification (or notification) and not the active talker
feature itself. Replace the MSG_ACTID parameter with the following:
Enables or disables Active Talker Identification (or Notification). Possible values are
ACTID_ON or ACTID_OFF. ACTID_ON is the default. This parameter does not enable or
disable the active talker feature, which is always enabled. It only disables the notification to
the application program. The active talker feature sums the 3 most active talkers in a
conference, so that the conversation doesn’t get drowned out when too many people talk at
once. Active talker notification provides data on active talkers through the dcb_gettalkers( )
and dcb_GetAtiBitsEx( ) functions, which can be used by an application program to identify
active talkers; for example, to provide a visual display highlighting the active talkers in a
conference. Active talkers are determined by their loudness; i.e., the strength of their “non-
silence” energy.
Note: In some cases, it is desirable to inactivate the active talker feature, such as for a
background music application program. Although you cannot directly disable the
active talker feature, you can set the noise level threshhold by which signals are
recognized as either speech or noise.
