Patents by Inventor Robert Pullman

Robert Pullman has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11388540
    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.
    Type: Grant
    Filed: January 4, 2021
    Date of Patent: July 12, 2022
    Assignee: SONY INTERACTIVE ENTERTAINMENT INC.
    Inventors: Scott Wardle, Robert Pullman

  • Patent number: 10887717
    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.
