This is a free demo version of the application for the analysis of spectral sound harmonics. Using the demo version you can perform simple experiments, and see the main advantages of this device.

The algorithm uses the properties of the human voice, which change the properties of the frequency spectrum of the sound, depending on the specific emotions.
This device can be operated in different modes. The applications of this device are much more diverse than that of a conventional polygraph.

It should be noted that this device is not a conventional polygraph. It is a versatile 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.). The site of the developer has a detailed description and some examples of 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 only 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.
