Music signal equalization in a changing environment

The paper presents the concept of an automatic system for music signal correction, considering room frequency response and music genre being played. The proposed algorithm, based on the room frequency response, compensates acoustic conditions surrounding the sound source. Additionally, the compensation process considers the signal content by recognizing music genre. As part of the described research, a series of subjective tests was presented to assess the effectiveness of the proposed algorithm depending on the music genre and acoustic conditions. The subjective tests described were carried out in accordance with the Mushra and AB methodology. In total, over 80 people took part in both tests and the results obtained from them were tested for statistical significance with the ANOVA test.
