On my Win 10 PC w/ SF Pro, the iZotope RX Elements <.dll> VST plug-in files are in "Program files> Steinberg> Vst plugins". However, AS (Audio Studio) does not include RX Elements, nor does it include the NR 2.0 legacy suite.
According to the AS user manual, the Audio Restoration items AS does have are in the 'Effects' menu which are installed automatically.
Sound Forge Pro 14 includes the legacy NR-2.0 .. and.. iZotope's RX Elements. Audio Studio (AS) does not include either. AS does have 'restoration' plugs though: DeClicker, DeCrackler, DeHisser, DeClipper. I do not know how they compare to the NR-2.0 or RX suites.
Actually, AS only has the basic denoiser/declicker combo, a legacy feature from the Sony days.
Correct. The new Sequoia effects (as MAGIX calls them, in reality they're probably 10-15 years out of development) are only in Sound Forge Pro - not Audio Studio. I believe those were added in Sound Forge Pro 12.
I am not sure how Noise Reduction Pack 2 compares to the MAGIX additions, because I've basically never used them. I had RX for a while, and iZotope is better than both, so I never bothered to compare them two.
MAGIX should bundle something other than iZotope Elements with their software. iZotope gives those away like 5x a year, now, so there is no value in those bundles.
Izotope only introduced VST3 support with their RX 8 release.
Sorry, completely incorrect!
Ozone 8 and 9 (the latest version) along with RX 7 and RX8, together with a number of their "smaller" plugins are all installed on my computer in both VST2 and VST3 formats, in both 32 bit and 64 bit, except for RX8 and Ozone 9 which are 64 bit only.
