oggdropXPd is a simple, drag-and-drop encoder and decoder that converts WAV files to the open "Ogg Vorbis" format or visa-versa. The program includes auto-tagging, renaming of encoded files, setting of advanced encoder parameters, use of VorbisGain tags on decode, playlist (.m3u) creation,
and others. Encoding options can be configured by right-clicking on the program window.
