The invention discloses a post-processing method and device for improving voice listening feeling, equipment and a medium. The degree of contrast stretching can be limited through the pre-configured maximum contrast stretching value, and signal distortion caused by excessive stretching is prevented. When the target contrast stretching parameter of any frequency is determined, the target contrast stretching parameter is determined by dividing the preset contrast stretching preset parameter corresponding to the frequency by the preset contrast stretching maximum value, so that the energy of the human ear non-sensitive frequency can be effectively reduced, and the energy of the human ear sensitive frequency can be kept. And subsequently, stretching processing is performed on the amplitude spectrum of the current voice frame by applying the target contrast stretching parameters corresponding to the frequencies so as to obtain a stretched amplitude spectrum, and the stretched amplitude spectrum maintains the energy of human ear sensitive frequencies and reduces the energy of non-sensitive frequencies on the basis of maintaining the original voice signal characteristics, so that the accuracy of the speech signal quality is improved. And the problem of numerical value overflow caused by excessive stretching of the amplitude of the human ear sensitive frequency is avoided.
