One of the key limitations in spatial audio rendering over loudspeakers is the degradation that occurs as the listener`s head moves away from the intended sweet spot. In this paper, we propose a method for designing immersive audio rendering filters using adaptive synthesis methods that can update the filter coefficients in real time. These methods can be combined with a head tracking system to compensate for changes in the listener`s head position. The rendering filter`s weight vectors are synthesized in the frequency domain using magnitude and phase interpolation in frequency sub-bands.
