Abstract
Movement of a sound source toward or away from a listener may be simulated by crossfading a sound level of a point sound source signal representation of a source waveform and a spherical harmonic representation of the source waveform as a simulated distance of a listener from a sound source changes to generate a cross-faded waveform. A speaker may be driven with the cross-faded waveform.
