AN AUTOMATIC EQUALIZATION ALGORITHM FOR AUDIO

We present a method for automatically equalizing music and audio signals based on information extracted from the signal. The main goal is to enhance the perceived audio quality especially if the sound quality of the audio signal is unsatisfactory. This method is based only on information contained within the audio signal, thus no further informa-tion is needed about recording conditions and equipment. The method adapts the equalizing in such a way that it re-duces the self-masking within an audio signal, in this way increasing the audibility of the information contained in the audio signal. Assuming that audio quality increases with the audibility of information within the audio signal, this approach will lead to an improved audio quality.
