Binaural signals of moving sources are synthesized using head-related impulse responses. The ear signals are synthesized such that the physical properties are correctly contained. The source signal at each time intsance is filtered by the instantaneous head-related impulse response and this wavelet is superimposed at the external ear. A number of properties of synthetic binaural signals are investigated. The spectral shift and head shadowing effect are analyzed in the time domain and in the time-frequency domain. The interpolation/extrapolation methods are employed to compute unmeasured head-related impulse responses. Artifacts caused by these processes are briefly reviewed.
