Patents by Inventor Raymond Montagne

Raymond Montagne 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).

  • For externally clocked digital audio input, determining a valid clock and muting audio during synchronization
    Patent number: 7884741
    Abstract: Methods and apparatus for determining the existence of an external clock over a digital input port on a computer. In one embodiment, the external clock is validated, and a lock is performed when the clock is valid. Whenever a loss of the lock is detected, and, if a re-lock is likely, the apparatus is muted so that audio artifacts that would otherwise be heard are minimized. The methods and apparatus also provide automatic re-locking to the external clock when a sampling rate change is detected.
    Type: Grant

  • FOR EXTERNALLY CLOCKED DIGITAL AUDIO INPUT, DETERMINING A VALID CLOCK AND MUTING AUDIO DURING SYNCHRONIZATION
    Publication number: 20080143566
    Abstract: The present invention provides a method and apparatus for determining the existence of an external clock over a digital input port on a computer, and, if the external clock is valid, locking to it. A loss of the lock can also be detected, and, if a re-lock is likely, the computer system is muted so that audio artifacts that would otherwise be heard are minimized. The computer system of the present invention automatically re-locks to the external clock if the clock has changed, as in the case of a change in sampling rate.
