oggdropXPd is a drag-and-drop Ogg Vorbis encoder/decoder/player for the eXPerienced user. Features include compression from lossless files (Monkeys Audio, LPAC, FLAC, WAVPACK and OptimFROG), auto-tagging, renaming of encoded files, setting of advanced encoder parameters, use of VorbisGain tags on decode, playlist (.m3u) creation, and others.

Version 1.8.7 introduced correct channel mapping for encoding of multi-channel (3 to 6 channels) files that conform to the WAVEFORMATEXTENSIBLE standard and provides the correct corresponding decoding and channel mapping in creating WAVEFORMATEXTENSIBLE conforming output wave files.

Playback also supports multi-channel in the same way. A further option is added to downmix multi-channel to stereo for decoding to file, or playback. The multi-channel mapping conforms to the Vorbis I Specification.
