Pair ABX test works like regular ABX test but with the difference that X is never one of the options A, B, C, ... but instead a pair audio sample of one of these. The user's task is to tell if X is closest to A, B or C. Correct selection means the user chose the option which is the pair of the randomly selected X.
Options song-1-transducer-1 and song-1-transducer-2 are always the fixed A and B references. The test randomly selects either song-2-transducer-1 or song-2-transducer-2 as X. A and B sound slightly different because ther are recordings of an audio clip played back with transducer-1 or transducer-2, both of which introduce their own timbral cues to the recording. The same timbral cues are present in song 2 and the user's task is essentially to tell if X is a recording of the same transducer as A or B.
