         final Float calculateLevel(ByteArray buffer, Integer readPoint, Integer leftOver, Boolean bigEndian)

        Calculates the normalized audio level (0.0 ~ 1.0) from the given buffer.

        Parameters:
        buffer - PCM audio data
        readPoint - Start index in buffer
        leftOver - Number of bytes to ignore at the end
        bigEndian - True if buffer is big-endian, false for little-endian (optional, default: BIG_ENDIAN)
        Returns:

        Normalized audio level
