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.
