2.9 About Audio
The DVS software provides a full support of audio during record or
play-out operations. Up to 16 different channels of audio can be in- or
output by the system. The audio data can be accessed and processed
in the software as easily as the video material.
When performing a record operation, the audio data can be input ei-
ther embedded in the video signal (audio in video, AIV) or via the sep-
arate digital audio connectors. You may have both signals connected to
the DVS system and prior to a record you have to specify the type of
signal that the system has to capture (see section “Configuring the In-
put Settings” on page 4-2). However, for an input of audio data a sam-
pling rate of 48 kHz is supported only. In case you want to capture
audio alone, a video signal has to be present at the system’s input and
the video format settings have to be set accordingly. Regarding the cre-
ated files, when no container format has been selected, you can choose
between several file formats for the audio files (e.g. *.aiff or
*.wav). Only one file per record will be written which will include all
the selected audio channels (audio file containing multiple channels).
On the other hand, when performing a play-out operation, you do not
have to configure the way a play-out of audio is performed. It will be
played out simultaneously, embedded in the video signal (AIV) as well
as via the digital audio output connectors.
The operation mode configurations provide in each operation mode
16 audio peakmeters – one for each audio channel – to monitor audio
during record or play-out operations:

The peakmeter for the playout mode can be found among the Output
select items (see section “Selecting Essences for Play-out” on
page 3-6) and for the ingest mode under the Input select settings (see
section “Selecting Essences for Record” on page 4-3).
Additionally, there is the audio monitoring tool available which allows
you to adapt the streamed audio that can be heard at your workstation
(see section “Audio Monitoring” on page 6-8).
