Hi,
we need some compensation for rounding errors in the spectrum element at
several places:
a) The number of samples per interval is rounded down ( interval * GST_SECOND /
rate ) which results in more spectrum messages over time than requested
b) The timestamps of the messages are calculated from the first buffer
timestamp + n * interval. Because of a) this results in timestamps lacking
behind the real stream time.
