We present analysis of a new method for fast and continuous acquisition of head-related impulse responses and, hence, a perspective for individualized binaural rendering of dynamical auditory environments. In particular, we compare the accuracy of our data-driven continuous acquisition method with the state-of-the-art in interpolation of discrete impulse response tables. The numerical comparison of the accuracy is achieved on the basis of the respective mean-square impulse response errors of both methods. It turns out that our data-driven method is not only most convenient in terms of the acquisition process, but also provides a lower bound in terms of the resulting inaccuracy of the head-related impulse responses. We finally present the architecture of a realtime rendering engine which makes use of the fast and continuous acquisition method.
