  • System and method of identifying the onset of a sonic event
    Patent number: 6704671
    Abstract: The present invention provides for a method and system for identifying a sonic event of interest within a received audio signal. A sonic event is characterized by a predetermined rate of change in the perceived audio volume, and is associated with the loudness of the audio. The present invention detects a sonic event such as a percussive hit without requiring that the detector be disabled for a fixed time to avoid false triggering. Because the detector is not disabled during the detection process, sonic events occurring in close proximity are easily recognized and not ignored as in some conventional systems.

  • System and method of aligning signals
    Patent number: 6594601
    Abstract: The invention provides for a method and system for mixing two signals, a primary signal and another sample signal, in a manner that avoids the cancellation of certain frequency components in the resulting mixed signal. Advantageously, the resulting combination signal therefor likely retains more of the fullness of the original two signals.
