A method for storing compressed data indicative of an analog signal and reproducing that analog signal from the compressed data. The analog signal to be stored is superimposed on a rectangular coordinate system. An elementary interval is defined on the X-axis of an X-Y coordinate system for the selection of a first series of points, a second series of points (R1, R2, R3) is determined by establishing a threshold ratio between the chord (C1, C1') separating two non-consecutive points and the sum of the chords (C1, C2, C3; C1', C2', C3') separating each of the consecutive points within two non-consecutive points. An interval (N) between these two non-consecutive points is selected to correspond to the maximum ratio below this threshold. The analog signal is reconstituted by generating a signal having a curve that is plotted by establishing between each group of three non-consecutive points a parabola with respect to the axis of symmetry corresponding to the axis of the elementary intervals.
