Abstract
A method for simulation of movement of a sound source comprising convolving a source wave form with at least an Head Related Transfer Function (HRTF) to generate a point sound source at a simulated first distance from the listener, generating a spherical harmonic representation of the source waveform at a simulated second distance from the listener, crossfading the sound level of the point sound source and the spherical harmonic representation of the source waveform at a simulated second distance from the listener and driving a speaker with the cross-faded spherical harmonic representation of the source waveform and the point sound source.
