8.2 Meta data file ”xxxxxxxx.xml” (Bsp. 10160233.xml)
With every saved ”xxxxxxxx.wav” audio file, an additional information file ”xxxxxxxx.xml” is saved, following the
same numbering convention, and containing various meta information on recording time, date, location,
temperature and the BATLOGGER parameter settings.
Example of the content of an *.xml meta information file:
<BatRecord> The .xml info file contains the following information:
<Firmware>2.0</Firmware> The firmware of the BATLOGGER was version 2.0
<SN>1016</SN> The BATLOGGER's number was 1016 (Serial Number)
