What Is a Computer Voice Stress Analyzer?

A resident of Wellington, Florida, Dr. Charles Humble is the founder and president of NITV Federal Services (NFS), the world’s leading forensic voice stress analysis company. As the founder of NFS, Dr. Charles Humble helped develop the Computer Voice Stress Analyzer in 1986.

A Computer Voice Stress Analyzer (CVSA) is a truth verification tool used by over 2,500 law enforcement agencies, including the US Military Special Forces, Atlanta P.D., and the California Highway Patrol. A CVSA comprises a microphone that is plugged into a computer that analyzes and displays an individual’s responses to questions. When using the tool, you don’t need to attach wires to the subject whose responses are being tested as you would do in a polygraph. The only thing required is the microphone, which captures the subject’s voice.

The manufacturers of the CVSA don’t claim that their devices can detect lies. Instead, they market them as devices that can measure micro tremors, which voice pattern changes caused by stress or the physical effort when someone is being deceptive. CVSA devices have been used to interrogate suspects and verify witness statements in homicide, robbery, and white-collar crimes, among others. They have also been used for pre-employment background checks.

Tips for Incorporating Experimental Photography Techniques

Since July 1988, Dr. Charles Humble has served as the president of.NITV Federal Services (NFS). When not working for the West Palm Beach, Florida-based company, Charles Humble pursues his artistic pastimes, which include photography. Below are tips for incorporating experimental photography techniques into your work.

You can employ experimental photography techniques during any point in the process. Even when selecting equipment, you can consider what setup will produce the images you desire. Digital cameras may contain settings that, when applied, will alter the photos you take in some way, like changing how colors appear. Using a digital camera, as opposed to a camera that uses film, will also open up different possibilities.

When in the field, you can introduce various elements that will affect the end product of your shoot. In a dark location, by setting your digital camera to a long shutter speed and running across the frame with a flashlight, you will imprint any shapes formed by the light onto the finished image, while you are not visible. You also can use intentional motion blur (IBM) by moving your camera while the shudder is open to add the illusion of motion to your images.

Using Experimental Musical Techniques When Creating Songs

The president of NITV Federal Services (NFS) for more than 30 years based in Florida, Dr. Charles Humble has created software used by thousands of law enforcement agencies nationwide. Engaging in many artistic hobbies, Charles Humble records acoustic music and vocals and distributes his work online. Experimental musical techniques can be used during any step of creating a song, resulting in a dynamic listening experience.

Though digital music creation, mixing, and mastering software give people more tools to work with, they are qualitatively different from playing a physical instrument. If you play an instrument, or have a history of doing so, use that experience to guide you. Record yourself improvising on that instrument every day, and after several weeks, listen to those recordings. Use material from those improvisations to inspire new work.

Alternatively, if you want to embrace the opportunities afforded by digital instruments and software, you can use techniques like field recording. By capturing sounds, spontaneously or planned, in a space outside a traditional recording studio, you can produce more varied work. If you wish to introduce spontaneity into a recording or live performance, use randomness to determine what notes, rhythms, or other sounds play. If performing live, you can employ these techniques to ensure that no two performances will sound exactly alike.

Best Practices in Travel Photography

Taking inspiring travel photos takes more than a good camera. Travel photographers start their research before they arrive at their destination to capture the essence of a landscape or culture. Learning about normal weather patterns, etiquette, and any significant festivals scheduled for that time of year can make it easier to plan out photoshoots and determine which type of equipment to bring.

Travel photography experts recommend packing a tripod. This tool can help keep the camera steady while adjusting the settings. Tripods also make it easier to capture moving images, such as flowing water. They are essential for long-exposure photography, which requires the camera to be still for long periods. Some camera equipment, like batteries, are sensitive to extreme temperatures. Photographers heading to very cold regions should pack extras and additional memory cards in case of failure.

After arriving, photographers should spend a few days traveling around their destination to understand the layout. Photographers can coordinate their desired setting with the rhythm of the locals. These preliminary excursions can also help photographers build a “shot list” which includes all of the images they would like to capture during their trip. For example, dense urban areas in warmer climates tend to be less populated during the afternoon when the sun is hottest. Photographers interested in capturing landmarks in bustling tourist cities may encounter fewer people before dawn.

Many of the best photo opportunities happen spontaneously, so photographers are advised to carry their cameras with them at all times. However, getting the right composition and lighting can also require spending hours in the same location. This can be difficult to follow a planned tour with a rigid itinerary or to travel with non-photographer companions. Serious travel photographers may need to dedicate time solely to taking pictures.

Even if a photographer wishes to focus on landscapes or buildings, adding a human element can make photos more interesting. People walking by a large monument can help demonstrate scale, while photos with locals in the foreground can give insight into the local culture. Many travel photographers also produce portraits of local people.

Photographers who want to use locals as subjects should learn enough local language to ask people for permission before taking any pictures. While most people do not object to being in the background of a wide-shot photo, photographers must remain aware of locals’ reactions to their camera. Some countries have very strict data protection laws that can affect travel photographers, especially if they plan to use the image commercially.

Photographers are also vulnerable to theft since camera equipment is valuable and easy to resell. Travel photographers can protect themselves by buying insurance. Before traveling, photographers should record serial numbers and other information that may be requested by the insurer. Storing camera equipment in a specialized travel bag with secure pockets can prevent damage and theft.

Photographers traveling through areas with high rates of robbery or theft should keep their most expensive items in their hotel rooms safe. Likewise, photographers can also protect their images by frequently transferring the photos to memory cards and uploading the contents to an online storage base. If their camera or laptop gets stolen, the images will still be accessible.
