The invention embodiment relates to an audio equalizing method, which includes the following steps: executing energy spectrum estimation for frequency domain signal corresponding to the obtained speech signal, obtaining energy distribution, and then obtaining frequency band equalizing factor according to the energy distribution, executing frequency domain filtering process for the frequency domain signal using the frequency band equalizing factor, obtaining the signal after frequency domain equalization, obtaining signal after time-domain equalization corresponding to the signal after frequency domain equalization. In addition, the invention embodiment also provides an audio equalizing device. The invention embodiment can avoid application disadvantage of pattern equalizing technique in speech signal environment with dynamic real time variation, thereby compensating or strengthening speech signal corresponding to certain frequency band, and has the advantages of superior acoustic quality, simplicity and practicality and remarkable effect.
