4.8 RTA
UC Surface provides a real-time analyzer (RTA) in which x = frequency and y =
amplitude for every input and output. An RTA provides a close visual representation
of what you are hearing. It provides a view of the long-term spectrum of the signal,
such as the one third-octave spectrum long-term average of a musical performance.
To enable the RTA for any input or output, select its meter from the top of the screen.
The Quantum RTA provides several customization features that allow you
to view the RTA in the way that is most useful for your application.
Height. This provides a more or less granular display for the RTA.
Range. Use the Range controls to set the upper and lower decibel limits that the RTA
will display.
Hold. Use this control to set the peak hold time for each band of the RTA.
Average. Averaging is a mathematical process that takes multiple data samples and
performs division to acquire a statistically more accurate calculation of the response.
That’s a technical way of saying that it slows down the “real-time” of a real-time
analyzer.
At the bottom of the screen, you will find the signal meter.
This meter can be customized for your application.
