It is the tool for interesting experiments. This app will turn your smartphone into a ensitive device that will measure the parameters of any digital sounds (voices, noises, and music). The device uses a new algorithm that allows you to calculate the numerical parameters of harmonic spectra. The measurements are carried out simultaneously on four independent channels and displayed in an intuitive way.
The algorithm uses the properties of the spectrum of the human voice which varies depending on the emotions. That is, using the voice's spectrum, human emotions can be assessed. The device uses an original interface, in which there is no graphic representation of the spectrum. After all, if you put the frequency spectrum on the screen, it is beautiful, but it is not clear. Therefore, in this model there is no spectrum analyzer graph. But there is a set of digital features that provide a more accurate assessment of the process.
It should be noted that even though this device allows you to measure the parameters of voices (and hidden emotions), it is not a conventional polygraph. It is a universal measuring instrument, which is designed for a variety of scientific experiments. The device allows you to measure the harmonic spectrum of virtually any sound (voices, noises, music, etc.). That is, the field of application of this device is much wider than a polygraph. This is a very versatile tool, which can be customized to your specific goals. In addition to the automatic settings, there is a set of manual settings, which you can use to make a lot of interesting experiments. For example, you can customize the application settings for individual voices, and use the device as a polygraph. You can use this app to evaluate man-made noises or music. The site of the developer has a detailed description and some examples of possible practical applications.
NOTE: It should be borne in mind that no analyzer or polygraph can determine the truth with 100% accuracy. Our application is no exception. This app is intended for scientific experiments. The measurement results are not official opinion, and cannot be used to determine the truth in court, or in any official interview.
Learning to work with this application is as simple as learning to ride a bike. All you need is the desire and a little practice. Install this app and you will see the world of sounds from a very unusual perspective. To test it out you can download a free trial version, or learn about real-world examples of the application of this device on the developer's website.
