PH's RTA, Freeware by IFBsoft This Real Time Analyzer just displays levels by 1/3 octave. The "Run" button makes it work. The "Freeze" Button freezes the image (storage). The integration time of sampling is set by checking 100 msec, 1sec or 10 sec. The Q-setting sets the slope of all filters; the higher the Q, the steeper the slope, the higher the separation of the 1/3 octave filters. Have fun Copyright by IFBsoft 2002
