AEQ Audio Over IP

Packet loss results in audio glitches, so it is very important to ensure that all receivers have their
latency set high enough to prevent packet loss.
Setting device latency too high, however, can interfere with low-latency applications (for
example, realtime monitoring when recording vocals), so it is sometimes important to find a
balance between low latency and guaranteed audio integrity.
The "Latency" tab can be used to identify devices that are dropping packets because their
latency is set too low, and also devices that could potentially have their latency reduced (if
required; generally, the default Dante latency of 1ms is more than adequate for low-latency
applications).
About the Histogram.
The transmitter's name is displayed at the top of the histogram, along with the latency value
against which the histogram is reporting.
The horizontal axis shows the distribution of audio packet latency measurements from the
transmitter. The vertical axis shows the number of measurements recorded at each data point,
on a logarithmic scale.
Measurements are taken at roughly 1 second intervals, from when "Dante Controller" is started.
To clear the histogram, click Clear. Latency measuring will then restart.
To save the histogram as a png image, click Save.
NOTE: If any subscriptions are via multicast flows, there may be two histograms displayed for
one transmitter: one histogram for the unicast flows, and one for multicast. This is because
multicast flows always use a latency of 1ms. If the receiver is set to a latency other than 1ms,
two histograms will be displayed.
