FIELD: physics. ^ SUBSTANCE: invention relates to a method of introducing low frequency emphasis into the spectrum of a sound signal converted in the frequency domain and containing conversion coefficients grouped into a row of units in which maximum intensity for one unit is calculated and the position index of the unit with maximum intensity is determined. A coefficient is calculated for each unit having position index less than the position index of the unit with maximum intensity, and amplification is determined for each unit from the coefficient and is applied to conversion coefficients of the unit. ^ EFFECT: more efficient encoding. ^ 29 cl, 28 dwg, 4 tbl, 1 app |
