Unsigned32
This attribute controls the number of averages
that will be performed on spectral bins.
The average will be computed using the 'leaky integrator'
method, where:
reported bin value = alpha*accumulated bin values +
(1-alpha)*current bin value.
Alpha is one minus the reciprocal of the number of averages.
For example, if N=25, then alpha = 0.96.
A value of 1 indicates no averaging.
Re-writing the number of averages will restart the averaging
process. If there are no accumulated values, the
accumulators are made equal to the first measured bin
amplitudes.
If an attempt is made to set the attribute to an unsupported
number of averages, an error will be returned.
