About the RTA

The RTS provides detailed visual feedback of the audio spectrum.

One of its uses is detecting frequencies where undesired feedback occurs. You can then use a PEQ to cut those frequencies.

The RTA can also be used to test the hardware I/O.

Connecting the RTA

The RTA block requires an input signal and doesn't send a signal out, so its output doesn't need to be connected.

How to view the RTA

Scroll to the RTA block and press Edit to view the dynamic meters. It makes for a great display during performances.

To make the peaks remain longer visible, adjust Decay Time.

Turn the Value knob to select the desired band, and the frequency of the selected band will be displayed in the upper left corner.
