Abstract
In a method and device for low-frequency emphasis where the spectrum of a sound signal is transformed in a frequency domain and comprises transform coefficients grouped in a number of blocks a maximum energy for one block having a position index is calculated. Also a factor having a position index smaller than the position index of the block with maximum energy is calculated for each block. For each block an energy of the block is calculated the factor is computed from the calculated maximum energy and the computed energy of the block and a gain is determined from the factor and applied to the transform coefficients of the block.
