|

|
|
<p class="hcp1">These settings are for the network audio behaviour
|
||
|
|
of the design file. The CobraNet bundle start numbering can be adjusted
|
||
|
|
here (default is 1000).</p>
|
||
|
|
<p class="hcp1">The default audio sample rate across the network
|
||
|
|
can be set here (choose between the standard 48kHz and the higher quality,
|
||
|
|
but higher overhead, 96kHz). As new BLU processors are dragged into the
|
||
|
|
design they will take their default sample rate from this setting. However,
|
||
|
|
devices can be run at the other sample rate as long as they are only connected
|
||
|
|
to other processors using the same sample rate.</p>
|
||
|
|
<h2><span class="hcp2">Latency</span></h2>
|
||
|
|
<p class="hcp1">There is also a selection of 3 possible latency
|
||
|
|
settings, this is the finite time that audio takes to pass thru a network
|
||
|
|
device and, if much processing is involved this can very slightly delay
|
||
|
|
the audio in the system. The maximum latency incurred in a CobraNet network
|
||
|
|
is 256 samples (5-1/3ms) at the receiving CM-1 card. This latency can
|
||
|
|
be reduced at the expense of CobraNet audio channels transmittable from
|
||
|
|
device to device and all units on the network must be configured to operate
|
||
|
|
at this latency.</p>
|
||
|
|
<span class="hcp2">NB:</span>
|
||
|
|
<br>If 96kHz is chosen the number of usable channels per
|
||
|
|
bundle falls from 8 to 4 if using a latency of 5 1/3ms, as shown in the
|
||
|
|
info box below. Shortening the latency will bring the channel count back
|
||
|
|
up to 8.
|
||
|
|
<p class="hcp1">This capability will be borne out so long as
|
||
|
|
fewer than 6 switch hops are used on a 100BaseT network. Greater than
|
||
|
|
6 switch hops may incur more delay. On a Gigabit network you may be able
|
||
|
|
to have 15 switch hops before incurring additional delay.</p>
|
||
|
|
<p class="hcp1">A CobraNet network utilising the CM-1 module
|
||
|
|
can make use of a number of possible latency times and sample rates.</p>
