I Need a Spectrum Editor...NOW...!!!...(found RX 2)
yo... check out this audio clip...my guitarist recorded it at his project studio w/ an AT4040 thru an old behringer eurorack: (it's a 16-Bit .WAV thru an embedded browser sound console): http://www.moonmixstudios.com/wavlinks.htm from the hornsby song 'talk of the town', the female vocalist sings: 'they say, you're running with the wrong set...the boy is someone you should never have met' now...for the lyrics 'say', 'set' & 'someone'...the sibilance there caused a sort of static crackle...(the waveforms have quick spikes that look like the type you see for clicks & pops) [& yes...I asked her if she was spitting when she sang & the answer was unequivocally no] and...for the lyrics 'you're', 'running', 'the' & 'is'...there is a nasty ring at the attack that sounds like mid fr. over-modulation (?) if there is such a thing [&...these syllables don't sound so bad w/ verb & in the mix...but they're clearly not right to begin with] so... 1) does you all agree on the above descriptions...??? 2) what is the best way to isolate these anomalies...???...[I'm thinking a spectrum editor plugin (w/ spectogram display)] 3) best way to return these passages to normal...???...???...[I'm thinking a spectrum editor plugin (w/ spectogram display)] 4) I'm running sonar7...do the newer versions have one on board...??? (if not...I'm up for suggestions) thanks much, mark4man btw - the reason I say needed now is because I've got to get this tune mixed & mastered in a day

sorry man...the post should have taken the direction of audio restoration...I went back & fixed it in regard to spectrum editing
thanx,

You need iZotope RX. You can get away with just the standard version though. I use it all the time...mostly because the spectral display is so good that it's see to see what's happening in the track, but also because it will let you edit out all manner of audio boo boos.

How much does that cost? I did a Google search and I'm seeing results in the $300+ range. Voxengo Soniformer might also be useful. It's $100. http://www.voxengo.com/product/soniformer/

Soniformer doesn't do anything like the same thing. In RX you can see the offending spikes, open the spectral repair tool and just remove them. No trying to dial in frequency ranges. No having to automate plug parameters to avoid damaging the rest of your material. I use RX all the time. You'll wonder what you did without it. It's probably the best $300 I've spent on software in ages.

I wasn't able to play your clip, but I suspect you have two separate issues going on: sibilance and resonance. The former can usually be addressed with a de-esser such as SpitFish (there are better but more complicated methods if that doesn't work). The latter can be addressed by a combination of multiband compressor and hand-automation.
These are common problems when you have entry-level microphones, inexperienced singers and untreated rooms. You don't need iZotope RX to fix it (but go ahead and buy it if you can afford it, it can do other things, too). You should be able to fix it with SPAN and SONAR-bundled tools.
 All else is in doubt, so this is the truth I cling to. My Stuff

I listened to the clip. Bit's right...it's not an RX problem. (I'd have her back away from the mic a bit next time though.)

bit & dan (& everybody)...
you're saying that iZotope RX will not isolate the crackle in the sibilance, or the resonance on the heavy syllables...???...(& therefore permit me to wash them out...???)
not sure how SPAN can help...I have SPAN but am not sure how to isolate these types of offending anomalies w/ it
[sure would like to be able to use RX to get it done]
thanx all,

You may already know this but if you hold down the Ctrl key while moving the mouse cursor in SPAN it will isolate the audio so you are hearing the audio where the mouse cursor is. Hold down the Ctrl key first, then click the left mouse button and drag. That makes it much easier identifying frequencies you want to work on. That's the most important thing right there... knowing which frequencies you want to work on. And you can use different MODE settings as well as manually tweaking the MODE in the EDIT window to further isolate the frequencies you are looking for.

I recorded the audio from the link you posted and played around with it a bit. I was able to identify the harsh audio by zooming in and looping it. I used a clip gain envelope to remove it since it was separate from the desirable audio. Didn't need SPAN or anything else. Here are a couple of images I captured of what I did to the first time she sang "set". After adding the envelope to it I can't hear anything wrong with it so maybe you could play around with an envelope and see how that works for you.

 " border="0" /> Hey Mark4Man - I dont hear alot of sibilance, what I hear more is the breath noise on the mic. As stated above, for next time you might want her to stand back from the mic and use a pop filter. To fix your problem on the cheap, you could try putting a highpass filter on the vox and see if you can lesson the deep sound of incoming air hitting the mic. As for the sibilance noise Chappel posted a great screen shot on fixing it via volume automation. For reference I posted an overview of a recent vocal track I mixed with all the volume automation. You cant be timid to pull up the sleeves and get in there with volume automation.

I highlighted one of the problem regions & went to Process > Au dio Fx > SPAN...but nothin'... hhmmm... (also: thanks everybody) mf

Put SPAN in the FX bin of the audio track and then double click it to open it. Then PLAY the track. or a portion of the track. SPAN is a real-time spectrum analyzer and gives you a visual representation of what you are hearing. On the Voxengo page I earlier posted a link to you can also download the SPAN User Guide and a Primary User Guide in PDF format. Both have a lot of great information in them that I have found very useful at times.

No problem. I'm glad I was able to offer some info that was useful. And I also suggest looking for the simplest solution. Like the use of an envelope. Fooling around with and tweaking frequencies is necessary when there is bad audio mixed with good audio. But if the bad audio is separate from the good audio it's easiest to just zap it with a volume or gain envelope.

Re:I Need a Spectrum Editor...NOW...!!! (found RX 2)
2011/05/20 15:52:23

actually... my pal ronnie morris tells me the performance did not cause the audio anomalies...& that, typically, electronic input chain problems such as the type heard are caused by: 1) bad mic, 2) cable [being stepped on/moved & thereby not being able to handle CMR] [both of which are external electronic problems] & 3) preamp [internal electronics - my guitarist's stupid behringer eurodesk mixing console]...but since it is happening frequently in the take...more than likely #3. in the meantime however, the iZotope RX2 module 'decrackler' fixed one of the 1st anomallies, as inserted into a selected region clip in sonar7...but then...as I inserted 'declicker' into a region down the line, it made the entire track hum/squeel (& caused a burp in the reverb)...all very weird.
[if I kick the region clips over to wavelab as exported wav's, I can repair them there & return them to the track in sonar...but that's a pain so i'm about to call sweetwater tech support on iZotope problems in sonar.]
i'll let u know when I get it sorted out...may help some other folks w/ RX2 difficulties. thanx,
mark4man btw - did the envelope lasso thing straight away...of course all that did was bring the crackle down w/ the siblance & it all still showed up in the finshed product. pulling the swing down further made the lyric sound unnatural.
