Three flags could also be shown, which indicate when external audio is selected, or various features
that impact readings have been set.
External audio source is being used for measurements
A speaker distance has been set and the displayed
reading incorporates the adjustment
A manual offset has been set and the displayed reading
incorporates the adjustment
More details on these settings are given in the Advanced Operation section.
Memory buffer and Statistics
Whilst measurements are being taken, the most recent 60 readings are stored in memory and are
available to view via the View Stats menu option.
When the memory becomes full, the oldest readings are discarded so it always contains the most recent
60 readings. This memory is retained between sets of measurements and only erased when Sync-One2
is turned off or cleared manually via the Clear All Stats menu option.
When the statistics are displayed the span and average of all the readings in the buffer is calculated to
better indicate the performance of the system under test.
The span is the difference between the two most extreme readings in the buffer. For example, if the
extreme readings in the buffer were -50ms and +100ms the span would be 150ms. A low span means
the system is stable in its operation, a span of 10ms or lower is ideal.
The average, calculated from all the readings in the buffer, gives an indication as to the true delay of
the system. Naturally an average of 0ms / 0.00 frames would be perfect but in the real world anything
under 10ms will be hard for anyone to detect.
Full details of the statistics provided are given in the Advanced Operation section.
Data Logging
Real time data logging of readings taken in Measurement mode is available via the USB Mini-B port.
Details of the data logged, format, and connection details are available in the API manual.
