I don't think this isn't the product, it's a how-to book.  The author probably just threatened to violate his NDA

Obviously it's just a book.  But unlike, say, announcing a book for January, 2019 on "How to Pilot Your Tesla Mars Rover with Windows 11.0," it's unlikely to be a joke (if it is, it's got to be the most esoteric joke ever).  So it does imply that Rx7 will be out by year-end and the feature set is already fixed enough to give a very fast writer (or maybe just a very sloppy one) time to produce copy.  So far as I know, there's no book on Rx1-6 that you could just update, either.

Ghosts......

So I upgraded from 5 to 6 yesterday, and the tools I've used definitely work better with less fuss than before, so totally worth it.  I was working on a studio recording with an acoustic guitarist who had tons of random noise, squeaky strap, managed to tap his foot on the edge of a music stand, etc.  Painted all that stuff right out like it never happened, can't hear any music damage.  5 would have taken a lot more do/undo/futz/do/undo cycles and not worked as well.

Okay, got a teaser email from iZotope today with subject: RX 7: Welcome to the New Frontier

It was blank, but their website offers, if you buy Rx6 today, a free upgrade to Rx7 when it is released LATER THIS MONTH.

Does anyone have any experience with the Rx 7? Are those features they promote usable for enhancing a stereo music recording, or is it marketing mumbo jumbo (I sure hope it's not) ?

Definitely a cool program. I wouldn't say it's a must have for tapers, but I don't think I've had the opportunity to use everything.

I need to find some old masters where I can try the De-wind and De-rustle plugins.

For RX7 the Music Re-balance tool is freaking amazing. No use for it for us, but it's fun to play with.

I want to try the demo and apply Music Rebalance to some commercial recordings I have where the vocal is WAY too loud in the mix.

The recordings I work with are simple 2 channel stereo concert recordings from either AT933 cards or hyper caps or audio reality binaurals.

Until recently, I’ve been using Audition 3.0

A few months ago I bought Izotope RX 7 standard as an adjunct. I’m still a neophyte as far as using all the capabilities of both Audition and Izotope – but – here’s what I’m finding about RX 7.

The promo videos constantly highlight music rebalance and music repair assistant features.
Honestly, for the type of recordings I have, these haven’t been as helpful as of yet.

What I HAVE found helpful are:

Clip Gain – although available pretty closely in Audacity, it’s been very easy to use to boost artist banter in between songs.

De –Click – probably the most outrageous module I’ve ever used to eliminate or drastically reduce clapping from people sitting close by. Select output clicks only and slide the choices up and down til you only hear the claps. Deselect output clicks only and render and the claps are almost totally gone or diminished so much that if you listen in headphones, they no longer bother you.

De Reverb – A subtle touch is required here, but for my recordings that had a bit of echo off the walls of the venue, this has helped to bring the audio of the instruments and vocals a bit more up front.

Spectral Repair – I’ve been learning to rely on the spectrogram views. For me, this is proving to be extremely helpful to reduce or eliminate those loud whistles that some audience folks insist on doing at various times. While both Audition and Audacity give good spectrogram views, RX 7 allows you to vary colors and level views so you can really see and highlight the offending noises. Then you can attenuate or replace from adjacent area. For me – great because I like to listen back to my recordings in headphones.

Spectral De Noise – I’ve only used this once so far. In one of my concert recordings, the artist wandered off stage and played his electric guitar off amp and sang without any amplification. The recording was extremely quiet and had hiss in the background. I was able to highlight the small bit of hiss/silence and get rid of it without (to me) any noticeable change in the audio I wanted to hear.

OK – so that’s what I’ve found really helpful in RX 7 standard.

On the negative side, the Equalizer leaves a lot to be desired. You get to use the EQ with some really nice features but to see your waveform, you need to open a separate window.

In RX 7 standard, there are no compressors or limiters included. RX 7 installs in both 32 and 64 bit. I’ve been choosing to use the 64 bit version. In 32 bit, I could include all the Audition VST plugins but they are all 32 bit. So instead, I installed the Tokyo Rose Koltenikov 64 bit compressor as well as the Loud Max 64 bit limiter.

That leaves the poor EQ choice.

I ended up buying the Ozone 8 elements plugin. This allowed me to see changes in the waveform in the same window as the equalizer. In addition, you can control very easily the audio you balance and hear in both channels equally. I can’t explain this easily – watch a video or download a demo to see what I’m talking about.

All this being said – I’m finding that I can both screw up or improve my recordings based on how much fiddling I do.

Again, keep in mind this review is what I’ve found helpful for 2 channel concert recordings that I’m trying to enhance or fix. There are other features that apply to multi-channel recordings that don’t apply to my usage.

For RX7 the Music Re-balance tool is freaking amazing. No use for it for us, but it's fun to play with.

Since I've had it, I've pulled many a buried vocal up out of an audience recording with great success, pulled bass up to match kick drum, bass down to match rest of band, drums down to match rest of band.  On the right sort of source, you can turn the bass player OFF like there isn't one at all, without it touching the kick drum.   Total lifesaver with stealth recordings, poor rooms, poor PA, poor soundguy. 
Title: Re: iZotope Rx 7
Post by: colargol on April 22, 2019, 01:16:19 PM
I picked up the elements package, and I have tried the de-clip function on some of my first digital recordings from my early taping days back in '93. Back then I did not even have internet (I don't know if DATheads was even started back then), so I didn't know how to do stuff. I used a crappy Sony microphone with my Denon DTR-80P, and unfortunately I used the high setting for the mic preamp on the recorder. So those recordings are all brickwalled like crazy...

So, long story short, these recordings are of course never going to sound great, but the de-clip function works great to recreate the dynamics of the recordings. I never though I would ever listen to them again, but now they sound pretty decent considering my equipment.

I am pretty amazed that it is possible to do this after 25 years... If you do do have brickwalled recordings, I would definitely recommend trying it  ;D

Noob question: do you run it stand alone, or as a plug in for a DAW,

Figure it wouldn't place nice in Audacity, but mayhaps Reaper.

I believe you can do either but I run it standalone. I've added some plugins from other places.

It installs both 32 and 64 bit versions.

You should try to use Connect if your DAW supports it as it is a badass feature and pop back and forth between RX and the DAW.  With that said, I tend to use it as a stand alone and make fixes before I put anything through a post in Wavelab 9

If only... Audacity does not support connect. So thinking rx7 first for clapping/screaming cleanup, normalizing, then into Audacity for the rest.

Thanks all. Played around w spectral repair yesterday and removed a yell from on top of Cortez the Killer. Was really cool.

When I used '7 declip last it was so far gone that it couldn't recover. Perhaps I've not set it up correctly. The overs seemed to be low end related and the post processing sounded... not good.

If anyone with a lot of experience in this would care to divulge settings, perhaps I can make it happen yet.

iZotope rx users, anyone care to take a stab at these samples?  Show last week there was some slight distortion/saturation in the vocals from the PA.  Much more noticeable on the SBD but on the AUD as well.  AUD is way to chatty to use alone!  I've gotten pretty good at iZotope but no luck with this one.  I've tried de-clip, de-crackle and de-rusle....... 

SBD sample first.  The first vocals (Well my baby) are probably the worst of the whole show but not sure.

AUD sample of the same spot

Listened to the first sample, and I can't see salvaging it (I am an experienced pro user). The distortion is baked in and can't be removed. A good analogy would be trying to clean up a guitar signal that was deliberately distorted through a drive pedal.

Sorry.

I used the stereo width function in RX 5 a lot but I can't find it in RX 7 Advanced. Did they remove it?

In RX 5 it was found under Channel Ops > Increase Stereo Width.

I know it's not the best tool around but it was easy to use and I only used it slightly when I needed a recording to breath a little more. Not to actually make it wider.

You could use the Ozone Imager plug in for stereo field manipulation. It is still free (https://www.izotope.com/en/products/master-and-deliver/ozone/ozone-imager.html). It will plug into RX7 32bit but not 64bit.  Works for me.  I have it working in both RX and Adobe Audition 3.0

I don't have the patience to do a whole set, but it's not hard just very tedious. Watch this vid.

https://theproaudiofiles.com/video/rx-6-instantly-paint-away-audio-problems-spectral-repair/

zoom in, you'll see the woo's as a long horizontal streak, use lasso tool to circle them, then use spectral repair,play with different settings, the vid uses the default setting. I used replace unwanted events-fast, then rendered.You can try the attenuate settings if you want. For the claps I use de-click on vinyl setting. Rx7 is hands down the best audio tool I've ever used. Going through so many analog masters recently and Rx7 is a lifesaver in many ways. Play with it and report back. It's pretty amazing to be able dewook an otherwise nice pull.

bedtime here will give it a go tomorrow, thanks again. is there a 'paint' or 'eraser' type tool instead of lassoing everything? those screams are long and linear
there's a brush function and magic wand right next to the lasso, haven't used either. watch a vid or two. now you see what I mean by tedious, 5-10 woos a minute in a 60 minute set = not a good time editing. maybe next time accidentally spill your beer on them so they will leave? avoiding the those peeps is half the battle if your on a solo mission. Curious to see what you can do with the set.

whistles are way up there, so fairly easy to remove w/out damage. You can use the rectangle select tool or brush select tool and the replace function.
whohoos I use brush select and attenuate at 2.7, usually twice on the base freq, and once on the first harmonic. For gnarly whistles, I've copied and pasted adjacent to the whistle for full removal w/out artifact. Used the rect select tool.

In general, I often don't touch the higher harmonics, there's not much energy there, and seems more likely to be noticeable.

Vinyl declick with defaults for claps is worth the cost of rx all on its own/

Any workflow for talking, anyone?

any other 32bit float recorder folks using rx?  I've been using it more and more so since I got the mixpre 6 II I decided to do all my editing in it since it opens poly wav and 32bit float.  Anyway editing went fine as expected.  I then tried to dither to 24bit with MBIT+

The file shows as 24bit in rx but when I save it the resulting file is still 32bit float!  What am I missing here?  Opened the file in wavelab and using MBIT+ via ozone plugin it dithered and save as 24bit like it should.

does wavelab still show zero bits? maybe it zero bittted below 24, and you intentionally need to save output as a 24-bit file

That's weird.  I use RX7, but only got a Zoom F6 a few days ago.  I do all of my final editing and converting in Reaper, after adjusting levels and doing noise reduction and applause reduction in RX.

After this coming weekend when I have a couple concerts, I'll see if I can replicate this behavior.

thanks and yes odd!  like the screen shot shows RX says it's 24bit but saved file is still 32.  I did find today that wavelab 6 seems to handle and save 32bit float without issue.  I even mixed and saved the aud and sbd at 32bit.

the old version of wavelab i used 20 years ago had a bit depth meter so you could see if your 24 bit data was really 24 bits and not 8 zero bits at the bottom.

i assume they still ahve that feature

yes but the meter only shows 24 not 32 but all 24 show on both the 32b float and the dithered version.

OK, I tried it just now.  When I import a 32-bit float file in RX7 and then export as 24-bit with MBIT+ dither, the result is a 24-bit file as expected.

Gordon, I have no idea what's going on with your setup.  The only difference between you and I is that we are using different brand recorders, but that shouldn't matter at all.

I'll mess with it later but I didn't "export".  That likely is my issue.  what I did was dither to 24bit and then did a "save as".  the saved file does show 24 when open in RX but the actual file is 32. 
Title: Re: iZotope Rx 7
Post by: Gordon on October 07, 2019, 08:54:22 PM
so yes it was user error.  never used the export feature before as I've never dithered with it.  anyway when exporting and selecting MBIT+ there is no way to configure the dither settings (noise shaping, dither amount).  should I assume it pulls those from what I set in the actual dither utility?

Yes, I believe so.  The same is true for RX's Batch Processing.  It uses the settings you had last configured in the modules you set for the batch process.

Depending on how important a "clean" recording is to you, it can take quite awhile to get this done. I haven't found a "setting" that you can just input and everything gets cleaned  up.

The way I've been doing this is to turn down the waveform slider so you only see the spectrogram view. Right click the spectrogram and view the spectrogram settings. For me changing the color scheme to "Cyan To Orange" works best for seeing the offending patterns.

For my process, if there's also clapping around the whoo or whistle I'll use the De-Click plugin first. This allows you to see the pattern of the whistle or whoo more clearly (you're gonna want to get rid of the claps eventually anyway). I've found that setting DeClick for "Multiband (Random Clicks)" works best. A general setting for me is sensitivity 3.7 and width at 2.3.

The way I determined this was to highlight the clapping and check output clicks only. I previewed the selection and adjusted until the claps/clicks were either attenuated sufficiently or eliminated and didn't affect drums or the overall sound.

The real time consuming part comes with the whoos and whistles. Expand the spectrogram view as music as necessary so you can learn to see which squiggly lines are whistles and whoos. For me, the paintbrush tool with settings of between 8 and 12 (depending on the thickness of the pattern or how fine I need to get). Carefully "paint" over the offending pattern/squiggly line and either "Replace" or "Attenuate" using the Spectral Repair plugin. I've been using Bands at 512 Surrounding Region at 100 and Before and After at 0.

After I spent several hours working on this, I kinda learned that sometimes you'll want to Attenuate the offending noise first and then Replace or vice versa.

An important thing to also watch for are the harmonics. The Whoos are usually just a single horseshoe shaped pattern. But you'll see whistles that are a loud, bright squiggle and then several fainter squiggles up above. If you don't get those as well, you get kind of a hiss sound.

A general intro to Spectral Repair can be seen at:
https://www.youtube.com/watch?v=QsZSuK6GczA

BTW, as Izotope and someone else on this board has pointed out, sometimes you'll want to render your effect several times. Like for Attenuate, you'll knock down most of the offending noise on the first render and even more on the next.

Once you get the hang of it, you can paint the loudest part of between song cheering and attenuate that. You can also paint some talking and test to see if that helps any.

Finally, one thing I just started to mess with in Spectral Repair is "Pattern". On a recent recording, a woman next to me quite loudly asked me to watch her drink while she left her seat for a bit. By Lasooing her talk and using pattern, I got satisfactory results of having her talking replaced. Unfortunately, she also nudged me and the mics prior to her request so the recording has a huge "clunk" that sounds like a bad edit or skip. Just gonna have to live with that on ;-)

Trouble is - it wasn't just the "clunk". This is working on a recording of Jason Bonham opening for Peter Frampton at Sandia Amphitheater. The song where this happened is in "Black Dog" and the house mix was very heavy on the bass. So where the "clunk" was, right where another beat of the song kinda happened at the same time. So when "pattern" eliminates the voice, it sounds like the sound just "jumps" as in a bad edit.

So, this is to me one of those situations where you decide to go for the best of ywo possible evils when dealing with a simple two track recording - I don't hear the talking but the "jump" passes so quickly, I can tolerate that in my headphones.

quick question I think I know the answer to but maybe I'm missing something.  Is there a way to undo edits in the history without it applying to all edits after that?  What I mean is if I go back in the history say 20 edits back it removes all edits after that.  Any way to just remove say #20 but leave all the rest after that?

I'm not sure if this is what you mean, but there is the action list on the bottom-right.  For example, a typical workflow for me in RX will be Declick > Gain > Spectral Denoise.  Each time I process / render one of those modules, it adds a step to that list.  If I want to go back to an earlier state in my processing sequence, I just go back and select it, and it recalls that state.

As long as you save your session with that file when you close RX, you should be able to access this recall list.

Obviously, once you export your processed file as a new file, you can't undo anything in that new file.

Does anyone here use RX7 as plugins in a different program other than the Isotope editor?

I ran DeClick (as a VST plugin) on a file in Wavelab6 the other day and it introduced a 3 second gap of silence every five minutes in the resulting render. Went back and did it again with the other VST plugin that's included in WL6 and no problems. Weird since I've done this same thing several times with no artifacts.

Yes each one can be "recalled" later by clicking on it in history but again it also removes every edit done after that effect!  See screen shots as an example.  You cannot just remove one earlier edit without it wiping out everything done after that!  You can clearly see where some whistles etc were removed.  if I go back and undo the ones on the left the other edits are lost as well.

Oh, I see what you're saying.  I mean, it's an edit history list, so of course it removes everything done after the earlier state you selected.

De-Bleed, nope.

Point something like a wide cardioid straight down at the talkers around your stand.   Use it as the bleed source to subtract from your main mics......

You can't go very far with it, and it's a slow offline process, but it can make a difference.   Test for sound quality on a very small section before committing to any larger selection.

whistles are way up there, so fairly easy to remove w/out damage. You can use the rectangle select tool or brush select tool and the replace function.
whohoos I use brush select and attenuate at 2.7, usually twice on the base freq, and once on the first harmonic. For gnarly whistles, I've copied and pasted adjacent to the whistle for full removal w/out artifact. Used the rect select tool.
i wish there was a way to select a pattern and drag it over a selection and match up the pattern, maybe there is?

I think you are talking about copying the selection then sliding it around to match other instances of the fault? Not sure that's possible, but you can add subsequent selections by pressing SHIFT then reapplying the selection tool. If your fault is significant and unique enough, you could try the Select Similar tool. Takes a long time if you "select  all" but it might work. Work on a copy and test lots of sensitivity settings.

I use the "Magic Wand" quite a bit, and in conjunction with the Select Harmonics tool, it's quite effective removing whistlers and such.

While I'm here I should warn anyone who struggles with the tragic effects of a bad clipping attempt and failed results. The Interpolate tool can save your bacon, if you have time and can settle for something just less than a great sounding patch. In my case, just OK is much better than a complete bust.

Have fun.

I have never used Neutron.  Personally, I don't see any of the modules as all that useful for post work on live concert recordings, unless you are looking to change the sound of your capture rather significantly. 

On a related note, I find Ozone highly useful.  EQ, Compressor, and Maximizer are all top-notch.  Too bad they removed the excellent reverb module a couple versions back.

You can't go very far with it, and it's a slow offline process, but it can make a difference.   Test for sound quality on a very small section before committing to any larger selection.

I expect for this to work well one will want to mic it so as to isolate the undesirable bleed (the nearby talkers) as much as possible in that channel while excluding the desirable sound as much as possible.  With that in mind, rather than a subcardioid I'd try something like a supercardioid pointing 45 degrees down and to the rear, such that the least sensitive sector of its pickup-pattern faces the stage and PA. 

One might imagine a vertically oriented fig-8 would be best to isolate local chatter beneath the mics while being least-sensitive to the desired sound arriving along the horizontal plane, and perhaps it will be for this specific application.  However, I've found the null plane of a fig-8 is generally too narrow to effectively isolate pickup of distant sources that have significant level in comparison to a cardioid or supercard facing away from the source.  The fig-8 null is deeper, especially in comparison to the rear-lobe of a super pointed directly away, but the more important attribute is how much reduction in sensitivity is achieved across a relatively wide angle.  It's the reduction in average sensitivity over a region that is more important in real world taper situations. 

It is for that reason I use rear-facing supercardioids rather than cardioids (or sideways oriented 8's) for the ambient channels in my OMT rig.  Even though it might seem pointing a cardioid null at the PA should maximully minimize the pickup of it, I've found that pointing the rear lobe of a supercardioid at the PA reduces pickup even more, due to the supercardioid's reduced average sensitivity across the entire rear-hemisphere in comparison to a cardioid.


Apologies for going OT on this, but it represents a very interesting, potentially powerful technique with applications beyond reduction of nearby talkers.  One of the driving forces behind the design my OMT rigs is arranging things so as to limit direct-sound bleed into the ambient channels and ambient/reverberant bleed into the direct-sound channels, while working with the relatively limited pattern directivity of first-order microphones and the need for sufficient correlation between adjacent imaging microphone pairs.  This technique could potentially be applied to actively manage this differentiation in useful ways, without needing additional microphone channels other than those already in the array.

Conceptually, it is akin to the DSP processing applied to the rear-facing supercardiod integrated into the Schoeps Super CMIT shotgun which further increases forward directivity over that of a typical interference tube shotgun design.  I'm talking about the potential of extending this from the domain of a single microphone to the entire multichannel array.

I'd try something like a supercardioid pointing 45 degrees down and to the rear, such that the least sensitive sector of its pickup-pattern faces the stage and PA. 
So the rear lobe of the supercard would be facing the stage and at a 45 degree up angle. Would that not catch a lot of the desirable sound coming from the stage? Would a shotgun pattern pick up less of that sound energy?

The collective direct sound and strong early reflections from stage and PA emanate from an area which covers a significant portion of the front hemisphere forward of the recording rig, let's assume around +/- 45 degrees horizontally and somewhat less vertically for sake of argument, more or less a 90 degree wide window.  What's most important is how much sensitivity is reduced on across that entire window.  As I mentioned above-

Even though it might seem pointing a cardioid null at the PA should maximully minimize the pickup of it, I've found that pointing the rear lobe of a supercardioid at the PA reduces pickup even more, due to the supercardioid's reduced average sensitivity across the entire rear-hemisphere in comparison to a cardioid.

So while a supercardioid has more sensitivity to sound positioned directly behind than a cardioid, the cardioid actually picks up more sound across that rear window (great movie BTW).  It still a good idea to orient the supercard such that the least sensitive sector of its pickup pattern, somewhere between 130-160 degrees off axis, faces toward the loudest sources and fortunately angling the mic down and to the rear serves to do that while simultaneously placing it on-axis with the mouths of folks immediately behind, which are the sound sources we want to focus on with this hypothetical arrangement.

I often angle my rear-facing ambient pickup pair of supercardioids so that each faces directly away from the PA speaker on the opposite side.  Sort of reverse PAS which typically results in an angle between them of around 40 degrees or so, which is desirable given their spacing and relation to the other mics in the array.  This does not increase pickup of the PA significantly compared to orienting those mics parallel to each other so that they face directly away from the stage, which comes closer to placing the PAs on the nominal "null" axis of both supercards.   

My take away is that it is generally more useful to think about pickup pattern sensitivity averaged over an area rather than in terms of specific null and lobe angles.

Hope that helps. 

Please pardon my interruption.  I'll now point this OT mic away from this thread so you all can return to discussion of the real world application of these powerful software tools as they currently exist.

De-click "Multi-band (random clicks)" with Sensitivity at 5 and Click widening at 4ms did a perfect job taming some outdoor New Years Eve fireworks.  Wow, just right, they settle right in to the mix now, instead of sounding like gunshots.

I am using the Spectral De-noise to try to eliminate some terrible white noise in a SBD pull for a different show.  It sounds like the ocean in the background.  It's cool how you can even lasso the right bit of high-energy noise you need to make your sample, and subtract it from the whole recording.

Well worth the $ I paid for it.

I think there is an Izotope tutorial on youtube somewhere when the guy is doing a seaside interview and edits out the ocean and some seagulls.  I bet that would help your use case Kev

I recorded a couple of concerts at the same venue recently and find the vocals a bit echo-ey (instruments sound good to me).

Should I invest in the standard version of Izotope ($299) and "fix" it with the deverb-functionality or would that be a wasted uphill struggle on a live recording (versus a studio recording)?

Deverb is heavy handed and obvious, I wouldn’t expect satisfaction from it.

Any tips for removing PA hum/noise in RX7? I’ve tried de-hum but it just killed the dynamics. Taped Tim O’Brien at a church and clearly, a church quality PA was the culprit.

Thanks!


Thanks all. De-crackle is amazing! A crackly fuzzy PA 90% better. Big thanks to DPK for showing me the way!

I ended up using spectral de-noise rather than de-hum in a similar situation. Key is to find a couple seconds when there isn't music, just the hum, and train the module on that.

+1 to this.  You want some clean "room tone".  I believe the minimum noise profile needs to be 0.1 seconds, but the the more you have to choose from, the better.

I always use the "Highest Quality" preset, and start with the Level at 6.0 and incrementally adjust up or down from there as needed.  I have found that to be a good starting point.

It is essential that you let your ears be your guide with this tool.  After training with your noise profile, switch between Preview and Bypass to make sure nothing is being negatively affected.  Also Preview with "Output Noise Only" and make sure you only hear noise.  If you hear any musical tones coming through (listen to the bass especially) then either you did not get a clean profile, your reduction level is too high, or both.

I am sure that all of these questions will be answered in the book "Audio Restoration with iZotope RX 7," which was announced almost two years ago (before iZotope had even announced RX 7) and which prompted me to begin this thread.  Although the Amazon listing for the book back then showed its cover design, the number of pages and a detailed contents, the book is still a phantom.  I recently found a projected publication date of May 15, 2020 on line at Presto Books, but the publisher, Hal Leonard, no longer seems to list it.  Anybody have any ideas about what is going on here?

^^^ That Find Similar tool does not work as well as one would hope. It certainly does not have "Find and Replace/next" functionality.

Best luck I've had is cleaning... sort of ... very clearly defined, consistently formed and isolated sounds. The clacking of a train over tracks is the only time I tried to use it and the results were not surgical.

The tool will take your first selected spectral shape or shapes and try to match it in subsequent minutes of file... every subsequent minute. It can take tens of minutes. When it's done searching, it marks them, (the next one or all of them) depending on your operational selection. You then either apply repair tools or you don't. There's no picking and choosing.

Prolly the most disappointing tool in the box.

Now that we're all spending lots of time indoors, it got me thinking: I have an old DAT recording that I managed to accidentally enable auto level control on. I was right in front of the stacks with Core Sound Binaurals. Just imagine how overloaded that sounds.

Would RX7 have any possible tools to help resurrect this?

Not expecting miracles but would love to know if anybody's got some quick tips for trying it out?  It was the only time the band reunited and played full set with many songs not played live by that lineup ever again.

Realize it's GIGO but hoping there might be some room for improvement.

^ I've seen a similar problem, and I should revisit it with what I've since learned; First try to hit it with the clipping tool to where everything is well below say -2dB. If you can still hear distortion when passing the old clipped peaks you should pause...

Then, and this takes patience and a huge investment in the value of success over expenditure of time... try the Interpolate tool. It works on a relatively small selection gap and efforts to generate a smoother transition between the entry point and exit. It would rival working from home to attack a fully afflicted show. It takes time.

If you still can't live with it, then the clipping repair was not fully effective and you wasted all the rest. But Hey, we're not going anywhere if you are on board with the madness.  Good Luck

You might have some luck with Spectral Repair, but it's hard to say for sure because every situation is different.

If you don't own RX yet and are wondering if it's worth it, I'm sure there are people here with some extra free time on their hands and would be willing to give this a shot for you if you shared the offending excerpt.

Me too, had a run of shows where lead guitarist's glasses bounced sound from his wedge into his vocal mic 20 times a show. Excised them entirely with no articfacting.

Perfect use of spectral repair.
