When trying to check the Hz level of a clip, such as in the case of an EVP. I go to ANALIZE then PLOT SPECTREM. But when I move the curser closer to the left the Hz level in creases and the Hz level decreases as I go right ?? An EVP is considered authentic if it comes under 300Hz. What settings should I use, and how would i con firm the clip of audio ??

You might want to change some of the spectrum analyzer settings. The tool is not the most useful at first birthday.
Change the samples from 512 to anything over 8000 and change the display from linear to logarithmic. Grab the lower right edge and pull the screen as wide and tall as you can. The accuracy goes up as you do that.
