# DESCRIPTION: Given a show that has already been uploaded to the IA, upload
|
||
|
|
# a locally derived set of files to replace those generated by
|
||
|
|
# the IA themselves. The IA's process of deriving files does not
|
||
|
|
# propagate the tags, which we really want to do.

For a show already on the archive it determines if the files are those derived
|
||
|
|
by the IA software and if not collects the WAV file (if necessary) and
|
||
|
|
generates all the derivatives (if necessary), then it uploads these
|
||
|
|
replacements. This is necessary because the IA's derivation process does not
|
||
|
|
copy the audio tags across to the derived files whereas we do.
