Input Ports

Port	Description
source primary	Input fileset.

Output Ports

Port	Description
result primary	Copy of the input fileset with all the audio files that are matched by the "media-types" and "not-media-types" filters replaced by transcoded versions of those files.
mapping	A `d:fileset` document that contains the mapping from the original audio files (`@original-href`) to the transcoded versions (`@href`). The `d:file` elements can have an optional `d:clip` child with attributes `clipBegin`, `clipEnd`, `original-clipBegin` and `original-clipEnd`, to indicate if the audio contained in the original audio file starts at an offset within the transcoded audio file. The attributes values are positive and are expressed in seconds (with millisecond precision).
