Chapter 8: The Display: RTA
Real Time Analyser
The RTA display allows you to see the response of your system, and see how the levels vary across the audio range of frequencies. You can inves-
tigate any gaps in the response, adjust crossover controls (if your system allows such niceties) and adjust any EQ controls you might have.
The display shows the frequency along the horizontal axis, and the signal level along the vertical axis. As an example, if you were playing a sine-
wave test tone, it would appear in the RTA as a peak centered around the test tone frequency. If you vary the test tone output level, then you will
see the displayed signal increase or decrease in level. If you adjust the test frequency, then you will see the peak move left or right in the display.
If you play a square wave test tone, then you will see the fundamental peak at one frequency, in addition to multiple smaller peaks at higher
frequencies. (A square wave is made up from a series of sine waves in combination.)
