Evaluation of the Circular Harmonics Decomposition for WDAF-based Active Listening Room Compensation
The underlying theory of most massive multichannel spatial sound reproduction systems assumes ideal, e. g. free-field propagation characteristics in the listening room. The effects of non-ideal listening rooms can be reduced by active listening room compensation. A very efficient realization of such a system is given by wavedomain adaptive filtering. Here spatio-temporal signal transformations ...
متن کاملEfficient Active Listening Room Compensation for Wave Field Synthesis
Wave field synthesis is an auralization technique which allows to control the entire wave field within the entire listening area. However, reflections in the listening room interfere with the auralized wave field and may impair the spatial reproduction. Active listening room compensation aims at reducing these impairments by using the playback system. Due to the high number of playback channels...
متن کاملActive listening room compensation for massive multichannel sound reproduction systems using wave-domain adaptive filtering.
The acoustic theory for multichannel sound reproduction systems usually assumes free-field conditions for the listening environment. However, their performance in real-world listening environments may be impaired by reflections at the walls. This impairment can be reduced by suitable compensation measures. For systems with many channels, active compensation is an option, since the compensating ...
متن کاملSound Field Synthesis
Conventional multichannel audio reproduction systems for entertainment or communication are not capable of immersing a large number of listeners in a well defined sound field. A novel technique for this purpose is the so-called wave field synthesis. It is based on the principles of wave physics and suitable for an implementation with current multichannel audio hardand software components. A mul...
متن کاملQESTRAL (Part 4): Test signals, combining metrics and the prediction of overall spatial quality
The QESTRAL project has developed an artificial listener that compares the perceived quality of a spatial audio reproduction to a reference reproduction. Test signals designed to identify distortions in both the foreground and background audio streams are created for both the reference and the impaired reproduction systems. Metrics are calculated from these test signals and are then combined us...
