Audio Files
Audio files that are used in voice overs are supported by the Channel
Branding feature. Audio files are created in the defined length that is
required for playout. The maximum audio element length, with 16-audio
channels, is 30-seconds. An audio file is played in its entirety unless it is
interrupted by a program or an effect transition. The audio file is config-
ured to play in one of the following modes:
• Play Once
• Loop
Each of these modes is described in detail below.
Play Once
The Play Once mode will play the entire audio element once and will then
stop in silence. The played audio element is then removed from the
Program bus’s output by a transition or a hot take.
Loop
The Loop mode will play the entire audio element constantly looping from
the end of the audio element to the beginning of the audio element. This
mode will continue until the element is removed from the Program bus’s
output.
Audio files are converted to the internal Channel Branding’s data format
prior to storage; this step is in preparation for playout.
The Maestro Channel Branding will accept and convert the following audio
file formats:
• Windows Audio Format (.WAV)
• Broadcast Wave (.WAV)
Channel Branding audio clips are played using 48-KHz sampling with 16-
bits per sample per channel (this setting is commonly called CD quality).
