1. A control device enabling a user to control a playback rate of a prerecorded file of signals, said signals being encoded in said prerecorded file in a continuous manner, said device comprising a first interface module for inputting control strokes, a second module for inputting said signals, a third module for controlling a timing of said signals and a reproducing device for reproducing inputs of at least some of the first three modules, said second module being programmed to determine times at which control strokes for a playback rate of the prerecorded file of signals are expected, said third module is programmed to compute, for a certain number of control strokes, a corrected speed factor relating to strokes preprogrammed as tags in the second module and strokes actually entered in the first module, wherein said corrected speed factor is determined by at least a ratio having as a numerator a time interval between a next tag and a preceding tag minus a time interval between a current stroke and a preceding stroke and as a denominator a time interval between the current stroke and the preceding stroke.
