In some streaming scenarios, the source audio stream might switch between stereo and mono. By default, Wowza Transcoder assumes that the number of audio channels doesn't change during a transcoding session. You can add a parameter to a transcoder template to instruct the transcoder to force any mono audio frames to stereo by duplicating the mono stream for both the left and right channels.
<Audio> <Parameters> <Parameter> <Name>default.scaleChannels</Name> <Value>2</Value> <Type>Long</Type> </Parameter> </Parameters> </Audio>
