It is. Ostensibly a collection of correction and repair tools, it’s spectral effects also allow for some really cool sound design.
EDIT: Keep in mind though that RX 7 Standard is much cheaper and only pared back a very little from RX 7 Advanced. Advanced gives you Ambience Match, Dialogue Contour and Dereverb, De-rustle, and Dialogue Isolate, Center Extract - all useful for post-production tasks - along with Azimuth control, EQ Match, Loudness, and Leveler modules, plus multi-channel support.
Good stuff, to be sure, but most of the coolest things (such as spectral de-noise, spectral repair, music rebalance) are available in the Standard edition.
