Annuncicom User Manual Version 4.07
Own Name
You can enter the name of the Annuncicom here. This name will be returned when using the DISCOVER
command (see technical documentation)
Default setting is "".
Streaming mode
"send always" will stream always
"send on TALK" will stream if the TALK button (command) is pressed
"send on Level" will stream if the incoming audio signal is above the Trigger level
"auto answer" will stream back for the Post Trigger Play duration after a stream has been received
"receive only" can receive a stream but will never send one
Default setting is "send on TALK".
Trigger level
Is only used when Streaming mode is "on Level".
Set to a value between 0 and 32767.
Open the Device status page and look for the Input peak value to get a hint for the trigger.
Default setting is "1000".
Pre Trigger Start
Pre Trigger Start can be adjusted to prevent cut offs when audio should be sent earlier than detected. It
defines the duration of the stream used before the actual trigger occurred.
This feature is normally used in combination with the send on level feature.
However, this parameter has a further use, to determine the receive stream strategy.
If 0, a minimum audio delay strategy is chosen at the receive side. Otherwise a minimum audio loss strategy
is chosen.
Default setting is "0" milliseconds.
Post Trigger Play
Post Trigger Play can be adjusted to prevent cut offs when audio should be sent longer than detected. It
defines the amount of time that the device will continue streaming after the actual trigger has been cleared.
This feature is normally used with the send on level feature. When Streaming mode is set to "auto answer"
this defines the duration the device will stream back after a stream has been received.
Default setting is "0" milliseconds.
Buffer Underrun Mode (TCP)
The Buffer Underrun Mode (TCP) defines the action if a TCP stream is slower than the real stream from the
encoder. In this case the output streaming buffer underruns and cannot hold older data anymore. The device
can then "disconnect" the TCP connection or it can "skip" the stream directly to the encoder stream without
disconnecting TCP.
Default setting is "disconnect".
Background Stream TCP Flow Control
The Background Stream TCP Flow Control defines data receiving strategy of stream interrupted by a priority
stream (so called background stream). If a priority stream is played, data in original stream can be either
accepted and thrown away or the TCP connection can be stopped.
Use throw away data if your streaming source is streaming in real time (e.g. Annuncicom). Use stop stream
when the streaming source is sending data as fast as possible (e.g. when sending a file from a PC).
This setting is only for receiving data and does not affect UDP streams.
