Towards Audio Signal Equalization Based on Spectral Characteristics of a Listening Room and Music Content Reproduced

This study presents investigations of the influence of the room acoustics on the frequency characteristic of the audio signal playback. First, the concept of a novel spectral equalization method of the room acoustic conditions is introduced. On the basis of the room spectral response, a system for room acoustics compensation based on an equalizer designed is proposed. The system settings depend on music genre recognized automatically. In order to acquire room acoustic characteristics, a series of measurements are performed. The impact of the enclosure on particular music genre spectral characteristics has also been presented. In the analyses a comparison of spectral characteristics obtained with pink noise and music genres as measurement signals is presented.
