Examples of net.pms.dlna.DLNAMediaAudio

net.pms.dlna.DLNAMediaAudio
This class keeps track of the audio properties of media. TODO: Change all instance variables to private. For backwards compatibility with external plugin code the variables have all been marked as deprecated instead of changed to private, but this will surely change in the future. When everything has been changed to private, the deprecated note can be removed.
