Audio streams and channels come in a wide variety of formats. In the spirit of keeping things simple, we support by default a single stereo stream and an eight stream configuration for 5.1 audio. Which covers 90+% of the content you will be dealing with. 

Please note, other options can be configured on request.

2 Channels or Stereo

This is the common case, which is commonly denoted as Left / Right audio, and is supported across all devices. This is where there is a single audio stream with two channels.

  • Channel 1 - Left
  • Channel 2 - Right

8 Channel or 5.1 Surround Sound

This is a specific arrangement of audio channels that supports encoding both for surround sound devices and for stereo supported devices. 

If the audio streams have been labelled, the encoder will use these. If the audio streams haven't been labelled, the following order is assumed.

  • Stream 1 - Left (FL)
  • Stream 2 - Right (FR)
  • Stream 3 - Centre (FC)
  • Stream 4 - Low Frequency Effects (LFE)
  • Stream 5 - Left Surround (BL) 
  • Stream 6 - Right Surround (BR) 
  • Stream 7 - Down mix Left (DL)
  • Stream 8 - Down mix Right (DR)
