摘要： The invention relates to a method for normalizing the power of an electrical signal, referred to as an original sound signal (S1), said method comprising the steps of: detecting the envelope of the original sound signal (S1); comparing the power value of the envelope signal (S2) with a threshold value (K1); calculating a gain signal (S3) in accordance with said comparison; smoothing the gain signal (S3) so as to obtain a smoothed gain signal (S4); delaying the original sound signal (S1) by a delay (T); and applying the smoothed gain signal (S4) to the delayed original sound signal (S1) such that a normalized sound signal (S5) is obtained. The method of the invention is suitable for a source including a plurality of channels. The invention also relates to a device for implementing the method.

摘要： The invention relates essentially to a method of optimizing stereo reception for an analogue radio, characterized in that it comprises the following steps: the right sound signal (SD) and the left sound signal (SG) demodulated are applied as input to a decorrelation module (5) having a variable decorrelation rate, the decorrelation rate of the decorrelation module (5) is modified as a function of the reception quality coefficient "alpha" provided by the radio, so that the smaller the reception quality coefficient "alpha", the higher the decorrelation rate applied by the decorrelation module (5), and the larger the reception quality coefficient "alpha", the lower the decorrelation rate applied by the decorrelation module (5). The invention furthermore proposes a module for generating high-pitched sounds which makes it possible to recreate the high-frequency component (SHF) of the right or left sound signals which has been removed in the event of poor reception.
