This paper discusses methods for preprocessing and digital filter design with application to 3-D sound. It is clear that binaural filter design can be optimized by taking into account such properties of human hearing as nonuniform frequency resolution and a logarithmic magnitude scale. The paper shows that by choosing proper spectral and time-domain preprocessing techniques, the choice of filter design method becomes a relatively trivial task. The validity of preprocessing methods has been proven using a binaural auditory model.
