If you?re annoyed with the stalled innovation process in iZotope product line (obvious during the last 2 years) you might have already found many mixing and mastering alternatives. Still it?s likely that you might be relying on the audio/dialogue restoration software RX. After the release of the latest money grab called RX 10 Advanced I assembled a long list of all features that are found in this software with and possible alternatives the Internet has knowledge of in order to find other software to substitute RX Advanced and avoid future upgrades to iZotope/Soundwide/Francisco Partners products. I hope that sharing this list might be helpful to some of you as well.


RX10 Advanced Features & Substitutes
(No Soundwide, No Waves Audio, No unsupported plugins)

Most substitutes aren?t stand-alone applications and need a DAW or audio editor as a VST/AU/AAX plugin host to be able to work.

Great post, you have done a lot of work. Thanks a lot.

Thank you as well for taking the time to read it.

Spectralayers has selection feathering (I think)
One advantage RX has is in the convenience of a single package containingg most of what one wants for repair work and editing
Also I find RX is visually clearer than Spectralayers - I wish I knew equivalent display settings for Spectralayers to those I use in RX

one of the reasons RX is not innovating is that the feature set is fairly mature as far as underlying technologies are concerned - with all tech innovation slows down as the tech matures.

Actually I don?t think this is the case. Noise reduction is one of - if not THE - main example of a place in audio where innovation is still both required and ongoing. Part of the disappointment in RX9 and RX10 is all the features it hasn?t included - to give one example, Acon Acoustica now has de-bird. I could list a dozen similar features that audio post is crying out for while iZotope faff around with useless crap like the text to speech feature that doesn?t work.

Not only has the pace of innovation slowed to a crawl, refinement has also been jettisoned. RX9?s Dialog Isolate introduced problems in the dialog detection algorithm, performing worse than RX8 and not corrected in RX10. The main NR algorithms are pretty good, but overall not as good as Waves Clarity, especially in real time use - and they haven?t been tweaked for years. Music Rebalance can be miraculous on some material, but is poor on others (and bettered by competitors).

I?ve never had to look elsewhere until now. But this excellent-looking list from Marina will prove highly useful. Perhaps a new section, Marina, for features that others offer not in RX at all? I suspect that section will grow in the coming months and years.

Interesting perspective, thanks. BOOM have a de-bird package as well. I have not tried the Waves Clarity, it gets pitched at vocals so I thought it was probably a bit specialised for me.
RX being a one stop shop is important to me tho - i dont really want to have a package of lots of different products to switch between
re algorithm development - commercial work seems to lag behind the academic world which is where I am most familiar. What I see in the commercial sector are variations on basic ideas from quite along while a go eg approaches to source separation which we were using in neuroscience long ago so for me those methods are quite mature. Similarly for signal detection eg birds - where they are probably using some sort of machine learning. Refinement is happening all the time of course.

Thank you for this list, I have tools to do many of these things already, but it is good to know about some products in order to do different tasks.

How is acon acoustica? It seems the best option between all of those plugins for audio processing and fixing..

Thank you for your kind words. I see there are functions available in other products that are absent and probably will never appear in RX. I would be very happy to see the thread grow, so feel free to add any such information to it.

Brusfri is a surprisingly good NR application https://klevgrand.com/products/brusfri

Thanks, OP!

Here's a few more that come to mind...

De-reverb - SPL De-Verb Plus

Audacity has some tools, and they list some alternatives

Acon Digital also has a Restoration Suite (DeNoise, DeHum, DeClick, DeClip)
https://acondigital.com/products/restoration-suite

Waves has quite a few

Yeah, me too. I do feel badly let down by iZotope, they became the industry leaders for a reason. RX was the great one-stop-shop. Now they've coasted for far too long, and their other products follow the same trend. When you've lost Pro Tools Expert, you know you're in trouble.

The miracles that Noise Reduction has brought us instantly become expected. You couldn't work in audio post without RX, producers and directors expected it. I'll never forget one producer asking me to take down the background in a single mono mic pickup barely 4 weeks after Dialogue Isolate first hit the market. He'd heard it done once somewhere, then expected it everywhere. Fortunately I had it...

One of the silly useless technologies in RX10 - audio to text - could be far more useful in a number of ways if they'd developed it properly. Being able to separate two voices - wow, that would be handy if it were reliable. Make changes to all of one voice, not the other. Even better, work with, say, 4 mics and then remove the bleed from the other mics in each. Or more broadly feed any source into RX and remove its ambient component in a file - PA spill, drum spill etc. All of these would be instantly and greedily gobbled up by the industry.

You would be way more core than me so if they aren't appealing to people like you then they are silly. Certainly they must have the established team who could do all of the stuff that someone like hit'n'mix seem to be doing

Oh and another useful feature this time for musical use - a dropout fixer. Just had to do this manually, it's a tedious and very imperfect chore. Anything out there that does this?
