The purpose of the class is to query the server for a list of files which
|
|
do not have a ReplayGain value calculated. This class will iterate over the
|
|
list calculate the values, update the server and repeat the process until
|
|
the server reports there are no files left.

|
This class will see heavy activity right after a 2.1->2.2 upgrade since 2.2
|
|
introduces ReplayGain normalization. A fresh install of Airtime 2.2 will
|
|
see this class not used at all since a file imported in 2.2 will
|
|
automatically have its ReplayGain value calculated.
