7.2.4 Parameters Specific to the Measurement Algorithms
The current PEAQ implementation provides several algorithm specific
command line parameters to:
•
Set the version of the algorithm (basic, advanced)
•
Set the listening level
•
Set the logging of the results
These parameters essentially follow the settings of the algorithm parameters
dialog and are listed with a short comment on their usage in the following:
Keyword Add. Parameter Comment
Version 0 = Basic; 1 = Advanced Select the Version of the Algorithm
Level Listening Level of a 1kHz
0dBfs sine tone Set the listening level according to
BS.1387
LogActive Switch logging on
LogODG float Logging if ODG <= float
LogInterval duration Logging intervals in s
LogFileName FileName Name of the logfile
PSQM currently interprets the following algorithm specific command line
switches. If no switches are specified, the default settings for correct
measurements according to P.861 will be chosen (45dB Hoth noise, 4kHz
upper limit, IRS filer, 101dBSPL listening level).
These commands are to be used together with the -Algorithm Name=PSQM
switch:
