    • Method Detail

      • getIntervalPeakLevel

        public float getIntervalPeakLevel()
        Returns interval scoped peak level. The peak level of last buffers. The UI update may not reflect some peak levels if the update period of the UI is greater than the audio buffer size. This value holds the peak level until it reset (by the UI). The user will not miss any level peaks. (Besides the peak hold value)
        Returns:
        peak level of last buffers

      • resetIntervalPeakLevel

        public void resetIntervalPeakLevel()
        Reset interval scoped peak level. The UI level meter should reset the interval peak level after the peak is displayed.

        Parameters:
        levelInfoToMerge - level info to merge peak levle hold to
        Returns:
        result level info (levelInfoToMerge)

      • merge

        public LevelInfo merge​(LevelInfo levelInfoToMerge)
        Merges this level info into given level info. Applies level properties to the given levelInfoToMerge level info, if the property value of this level info is greater than the corresponding property value in levelInfoToMerge. The properties are level, peakLevel and pekaLevelHold.
