Output Selection
Easysound has four AES/EBU stereo output channels available from a single
rear-panel connector of the host unit. For further details see Rear panel
connections below.
The AES/EBU stereo outputs at AES OUT 3 and AES OUT 4 of the
AES/EBU will be re-embedded into the SDI Programme digital video output
stream.
Easyplay
Easyplay operates as a combined digital AES audio store and player (note
that the host unit must be fitted with an Easysound card and must be
connected via Ethernet to Miranda Technologies Ltd's Windows NT™ based
Media Distribution System). Audio files used with Easyplay must be 16-bit,
48kHz .WAV format or Miranda Technologies Ltd's own .OXW format.
The audio store can store up to 40 minutes (optionally 200 minutes) of digital
audio, which can be sub-divided into a number of audio files.
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 audio file 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 audio file is faded, cut or swapped from the programme output
Audio Files
Audio files used with Easyplay must be 16-bit, 48kHz .WAV format or
Miranda Technologies Ltd's own .OXW format. Miranda Technologies Ltd
Media Distribution System (MDS) software is able to create these .OXW files
from 16-bit, 48kHz stereo .WAV format files. The MDS can also edit these
files and create the necessary image to audio linking.
