Room equalization (REQ) is a common method to adapt audio signals to the room in which they are reproduced in. REQ for example attenuates the audio signal at the room resonance frequencies, to reduce negative effects at those frequencies, when the signal is played back. REQ is a time-invariant method. Recently a time-frequency adaptive method to adapt audio signals to rooms has been proposed . The results of a subjective evaluation are presented in this paper. Amount of room reverb and quality are assessed in a blank room, same room with absorbers, and blank room with time-frequency adaptive processing.
