channels property

String? channels
final

The number of audio channels in the output file. The following values are valid:

auto, 0, 1, 2

One channel carries the information played by a single speaker. For example, a stereo track with two channels sends one channel to the left speaker, and the other channel to the right speaker. The output channels are organized into tracks. If you want Elastic Transcoder to automatically detect the number of audio channels in the input file and use that value for the output file, select auto.

The output of a specific channel value and inputs are as follows:

  • auto channel specified, with any input: Pass through up to eight input channels.
  • 0 channels specified, with any input: Audio omitted from the output.
  • 1 channel specified, with at least one input channel: Mono sound.
  • 2 channels specified, with any input: Two identical mono channels or stereo. For more information about tracks, see Audio:AudioPackingMode.
