Setting device latency too high, however, can interfere with low-latency applications (for example, real-

time 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:

n Devices that are dropping packets because their latency is set too low

n devices that are at risk of dropping packets because their latency is set too low

n 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.

The following information is also displayed:

n The latency Setting for the histogram. In most cases, this will be the same as the latency setting on

the receiver. However, for some subscriptions, Dante will automatically apply a different latency. For

example:

Multicast flows are automatically set to a minimum of 1ms

If a transmitter does not support the latency set on the receiver (i.e. it can't guarantee delivery

within the required latency), Dante will increase the latency to the lowest setting supported by
