AB  - The equalization of room acoustic influences on the sound transmission from a source (loudspeaker) to a receiver (listener/microphone) is a well known problem in audio engineering and academia that led to various equalization methods. However, many highly effective approaches lack of either robustness, practicability or usability. This paper thus presents an algorithm for room response equalization making use of parametric peak filters that are popular in audio engineering for their intuitive handling and performance. Motivated by the urge of controllable acoustic conditions for listening tests within immersive multi-loudspeaker audio reproduction, the presented algorithm was designed with respect to the recommendation ITU-R BS.1116-3. Results show, that spectral coloration can be reduced significantly, reaching conformity with the recommendation of up to 96%.
