+## Modifications
+
+The audio clips in this representative subset are transformed derivatives of
+one VCTK source clip. VocalGrad applies controlled time-varying transformations
+to create benchmark examples for detecting whether a target perceptual
+attribute increases or decreases over time. The included metadata identifies
+the source clip ID and the transformation condition for each derived clip.
