CAudioFile
CEOUtils::MetadataAudioFile	Abstract class that extends AudioFile with pure virtual methods for adding/updating common audio metadata (tags). Derived classes for audio formats that support metadata (e.g., FLAC, Ogg Vorbis) should inherit from this class and implement the metadata operations
CEOUtils::FLACFile
CEOUtils::SndFileBackedMetadataAudioFile	Shared libsndfile-backed implementation used by MP3, Ogg Vorbis, and AIFF codecs
CEOUtils::AiffFile
CEOUtils::MP3File
CEOUtils::OggFile
CEOUtils::WAVFile
