The acoustic response of rooms can degrade the reproduction of sound using loudspeakers, changing the frequency content and smearing the sound in time. This is an old problem that is still important and challenging. Conventional compensation systems address this by filtering the loudspeaker signals, with varying degrees of sophistication. However, this approach cannot address the late diffuse part of the room response, or the variation in frequency content across the response, which are important particularly for large rooms. The method proposed here addresses these issues by modifying reverberant content in the source so that it combines with the room response to give the best match to the original production. It is shown how this can be integrated in object-based frameworks, which are a future trend in broadcasting.
