Abstract
An example method includes receiving audio signals associated with virtual auditory space locations. Digital filters are selected based on the virtual auditory space locations. The digital filters include one or more notch filters including one or more center frequencies that are based on generally sigmoidal distributions of center frequencies as a function of virtual auditory space location. The notch filters are configured to produce one or more notches in frequency spectrums of audio signals when applied to the audio signals. The digital filters are applied to the audio signals to obtain processed audio signals. Output audio signals are generated based on the processed audio signals. The output audio signals are provided to devices for producing virtual auditory display sound.
