Quaudiophiliac (styled QuAUDIOPHILIAc) is a compilation album featuring music by Frank Zappa, released in DVD-Audio format by Barking Pumpkin Records in 2004. It compiles recordings he made while experimenting with quadraphonic, or four-channel, sound in the 1970s. Zappa prepared quadraphonic mixes of a number of his 1970s albums, with both Over-Nite Sensation (1973) and Apostrophe (') (1974) being released in discrete quadraphonic on Zappa's DiscReet Records label. Produced by Zappa, and completed by his son, Dweezil Zappa, Quaudiophiliac includes several previously unreleased works in this format. The recordings date from as early as 1970, with "Chunga Basement", a version of the title track from Chunga's Revenge (1970). Also included are three tracks from the 1975 Royce Hall, UCLA concerts with the Abnuceals Emuukha Electric Orchestra which would become Orchestral Favorites (1979); plus a quad remix of a segment of Zappa's 1968 musique concrète masterpiece Lumpy Gravy.
