FreeThis app will turn your Android into a sensitive 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 hi
