KDA Manager
Program Overview
The KDA Manager is a program used
to generate and convert audio files.
You can load these audio files indi-
vidually or load several in an archive
in the OpenCom 100 communica-
tions system and then use them in
the voice portal you created using
the OpenAttendant application.
■
You can use the KDA Manager to
convert audio files to the file for-
mats supported by the
OpenCom 100 (refer to the fol-
lowing table,
■
If a microphone is connected to
your PC, you can also record au-
dio files in the KDA Manager and
save these immediately to a
suitable file format.
Note:
A 10-second *.726 audio file
requires about 40 kbytes of space on
the memory card; a 10-second *.711
audio file requires about 80 kbytes. To
avoid using the memory capacity un-
necessarily, keep the generated audio
files as short as possible.
Detailed instructions on how to gen-
erate and convert audio files can be
found in the KDA Manager online
help.
