KDA Manager KDA Manager Programme Overview The KDA Manager is a programme used to generate and convert audio files. You can load these audio files individually or load several into an archive in the OpenCom 100 / Aastra 800 communications 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 formats supported by the OpenCom 100 / Aastra 800 (see the following File formats table). ■ If a microphone is connected to your PC, you can also record audio files in the KDA Manager and save them immediately to a suitable file format. File formats Source formats for conversion - CCITT Wave, A-law, 8 kHz, mono - PCM Wave, 16-bit, 8 kHz, mono Target formats for conversion Single file OpenCom 510/X 320 *.726 (encoded according to ITU G.726 32K ADPCM) OpenCom 130/131/150, *.711 Aastra 800 (encoded according to ITU G.711 A-law PCM) File archive *.kda (contains several *.726 files) *.kdp (contains several *.711 files) Note A 10 second *.726 audio file requires approx. 40 kbytes of space; a 10 second *.711 audio file requires approx. 80 kbytes. To avoid using the memory capacity unnecessarily, keep the generated audio files as short as possible. Detailed instructions on how to generate and convert audio files can be found in the KDA Manager online help. 6
