2. From the Channel menu, select a channel and click Encoding . The encoding configuration page opens.
3. In the Audio settings, ensure that Enable audio is checked to include audio in the channel.
4. From the Audio format drop down, select an audio codec (AAC, MP3, or PCM).
5. From the Audio channels drop down, choose mono or stereo (default).
Choose Mono to have left and right stereo channels combined and streamed together so
that when you listen to the streamed audio, the same blended sound comes through both
the left and right channels.
6. From the Audio bitrate drop down, choose a birtrate. For guidance, see audio bitrates . For stereo
audio, we recommend 256 kbps or 320 kbps.
7. Click Apply .
Multi-encoding and channel as a source
Pearl Mini lets you easily do multi-encoding so you can record and stream the same content at different
encoding settings. This is useful when you want to:
l
Record a video at a high bitrate and frame size and live stream the same content at lower encoding
settings.
l
Record the channel while also sending two (or more) streams of that channel using different encoding
settings for CDNs that don't use adaptive bitrates.
l
Or record the same channel simultaneously at different resolutions, like full HD and HD.
