The screen capture compares the gain tracking available for the Smaart i/o (out of production) and the Audient EVO4
Gain tracking for the Audient EVO4 is currently only available via the Smaart V9 Suite Beta version available via your my.rational account at Rational Acoustics ® (download section) if you purchased Smaart V9 Suite.
Please lower you systems volume because the calibration signal is kinda annoying (except for those who enjoy 1kHz sine waves).
Please read the PDF about the Beta version 😉
I did a similar screen capture a couple of years ago
Enjoy
