RunPeaqBasic.bat
C H A P T E R 5 : W I D E
In the following we will replace Basic and Advanced by XXX. These batch files
work together and perform several PEAQ measurements with different test and
reference signals. ConfPeaqXXX.bat calls RunPeaqXXX.bat several times,
each time measuring different wave files contained on the PEAQ Sample CD.
The wave files used in the batch file ConfPeaqXXX.bat are taken from the
DB3 database that was used in the ITU-R BS.1387 standard to verify the PEAQ
algorithm. DB3 contains several reference and test files and their corresponding
SDG values from the subjective listening tests.
A result file ConformanceReferenz.txt can be found in the root of your
PEAQ Sample CD. This file contains the result values of the PEAQ Basic
measurements for the DB3 database used by the ITU-R to verify PEAQ. The
contained values are tab-separated and can thus be imported into any
spreadsheet analysis program. Use this result file to verify that the delivered
OPERA™ system is working correctly.
The following will explain the mentioned batch files and explain how to save
result values in your own result file.
The following lines are the contents of the file RunPeaqBasic.bat. Please
notice that the commands after the keyword Opera -Exec have to be written
in one line in the batch file. Here, the line has to be wrapped in the absence of
space.
