Strategic Thrust: 
A scratched sound synthesizer plays back a sound clip at different time-varing rates to imitate the sounds a DJ produces on a turntable with different scratching techniques. The sound clip, called a scratchable unit, is usually speech with a few syllables. The scratched sound synthesizer turns the scratchable unit into a scratch comprising one or more strokes (e.g. a chirp scratch with a forward and a back strokes). It enables users without DJing skills to create realistic scratched sounds which can be used in music production.
