PEAQ Basic Final Results
Figure 5.29 shows the final results diagram for the Basic version of PEAQ.
This screen is a summary of the results obtained for the entire measurement
sequence, from the start point to the end point. The criterion for the start and the
end point is given by BS.1387. The start and stop point detection ensures that
measurement results are not falsified by silent periods at the beginning or at the
end of the files. The values shown in this diagram will not vary while moving
through the history buffer. These are also the values that should be reported as
the result of a measurement. Please note that the "Model Output Variables and
ODG" diagram may contain slightly different values for the ODG and DI than
the "Final Result" diagram, since only the latter takes the stop point of the
measurement into account, while the first one is measuring until it encounters
the end of any of the two input streams.

5.5.5 Diagram Types, PEAQ Advanced
Figure 5.30 shows the various diagram types available for the advanced
version of PEAQ. Most of the diagrams look exactly like the according diagrams
of the basic version, with the exception of the scaling of the time axis. The
following paragraphs will describe only those diagrams that differ significantly
from those of the basic version.
