Important Notes for File Playback:
· Ensure MP3 recordings used are not variable bit rate files.
· File playback audio is sent directly to the codec outputs and therefore IGC is not
available. When you create your MP2 or MP3 files ensure the audio levels match the
audio reference level of your codec and that peaks average at the correct levels.
· Backup file audio is only sent to the outputs of the local codec. File playback audio is
not sent to encoders and cannot be transmitted via an audio stream to another codec.
· Removing storage media while audio is playing from it will result in poor audio quality
and should be avoided. If it is removed accidentally reboot the codec to ensure failover
file playback will work in future.
· If you enter a single file name ensure you add the file extension, e.g. "test.mp3", or the
file will not play back.
· If you enter a directory name, all the files within the directory will be played back. We
recommend you save all audio files as a playlist and link to this if you want them to
