Input Settings
• The number of available audio channels per input source can be found in the
following table:
• The embedded audio from an SDI source is only available when SDI video is
selected, and the embedded audio from an HDMI source is only available
when HDMI video is selected.
¦NoteFor more information, see “Video/audio inputs and outputs” on
page 9).
• Monarch HDX uses the AAC audio format for streaming and recording. To
monitor the selected audio source, you can use any of the audio outputs
(SDI, HDMI or analog).
Audio Sample Rate
You can select the desired sample rate for either your digital or analog audio
input source.
Remarks
• Both digital (HDMI or SDI) and analog audio can be sampled, or re-sampled
at the embedded rates of 22.05, 24, 32, 44.1 and 48 kHz.
• The analog audio input is converted to the selected sample rate before
encoding.
• Selecting the highest sample rate provides the best audio quality, but also
increases the total bit rate required to maintain this quality for streaming
and/or recording.
For information on audio bit rate, see “Audio Codec Settings” on page 29.
Mute audio
Mute audio lets you mute the audio at any time while streaming or recording,
without interrupting your session. Selecting
Mute audio disables all audio.
¦NoteYou can also choose to not include the audio when streaming or
recording from within the encoder settings, before your session begins (see
“Include audio” on page 31).
