Audio playout
Easyplay has a single layer of audio insertion and the host unit's image keyer
triggers playout. The audio playout starts as soon as the image is brought to
air and makes a contribution to the programme output when voice over 1,
pair 1 is on. Audio playout continues until:
♦ the audio file ends
♦ voice over 1 is faded down
♦ the displayed image is faded, cut or swapped from the programme output
Where the host unit has both foreground and midground layers (Imagestore
in cascade mode) either keyer may trigger playout. However, once a layer is
on air with an associated audio playout, the playout feature is effectively
engaged. This means that if a second layer is brought to air while playout is
engaged, a second audio playout will not be triggered.
A custom remote control can be configured so that the audio file used for
playout may be selected for looping (enabling continuous play). Automation
commands using the host’s serial communications port may also select
looping.
Audio Files
All audio files used by Easyplay must be in Miranda Technologies Ltd's
proprietary audio file format and given an .OXW file extension. The Miranda
Technologies Ltd Media Distribution System (MDS) software is able to
create these files from 16-bit, 48kHz stereo .WAV format files. The MDS can
also edit these files and create the necessary image to audio linking.
