Audio multiplexing
Refer to the input formats table above to see the supported audio codecs, since audio streams are multiplexed (copied “as is”) from the ingested file into the processed media files in most cases. The audio streams are transcoded to 128 kbps AAC or 16-bit PCM format if the audio codec of the original media file is incompatible with the chosen container.
