Disclaimer: I do not know if this is real or not, and if it is on the Sukhoi Su-35 or not.

Audio Source: I cannot remember, but I think it is from DCS.
The only proof of this being real (that I can find) is here:
I like Airbus and Boeing GPWS. I try my best to collect rare GPWS, CAWS, TAWS and TCAS sounds. Some notable ones I have found are, Sukhoi Superjet 100 Landing Callouts, A300/A310 Windshear Aural Warning, and Boeing 737 Classic Config Alarms. Thank you for reading this messy description.
