Media-Store Audio
Audio can be added to the playout of a Media
-Store channel either by loading the file directly,
or by associating the audio file with the video
you want it to play out with. When you load the
clip, the switcher will automatically load the
associated audio file.
Keep the following in mind:
Keep the following in mind when working with
Media-Store audio:
• Audio files should be 24-bit uncompressed
WAV files at a 48kHz sample rate. Bit depth
of 8, 16, or 32 are also supported, but
playback bit-depth is not changed.
• Audio is embedded in the ancillary data of
the video stream that the Media-Store
channel is included in.
• Both of the audio channels are associated
with an AES port for that ME. Channel 1 is
locked to AES 1 and channel 2 is locked to
AES 2.
• Audio is loaded into the corresponding Media
-Store Audio channel as the Media-Store
video channel. For example, if you load a clip
with audio in video channel 2 the audio is
loaded into audio channel 2.
• Loading a clip with audio into a Media-Store
Audio channel only loads the audio and will
not load the corresponding video.
• An audio file does not need to be of the same
length as the animation it is associated with.
• Audio is played the same way an animation
is played.
• The length of an animation is set by the video
rate the switcher is operating in. Audio is
fixed at 48kHz. If your audio and video is
synched at a particular video rate, playing
the media at a different rate will result in the
audio and video being out of synch.
• Audio only looping is independent of video
looping.
• Video with audio will only auto start when
it is taken on-air, and not when it is loaded
or the properties are changed (as with video
only media).
• Audio always plays out at 1x speed, even if
the video is playing faster or slower.
To Associate an Audio File with Video
You can associate an audio file with a video file.
When the video file is loaded, the associated
audio file is also loaded.
