Topic: Is there software that removes cellph. RFI/ Is my recording toast?(w-whole show)

[igene]

My fault. My friend kept texting me for directions to the show while I was taping.
I had to respond. It happened 5 or 6 times during the recording.
He made it for the last 3 songs 

The recording is amazing, the interference is really obnoxious.
It ruins the recording 

Help !!!

It would be a nightmare doing this manually.

[Fatah Ruark (aka MIKE B)]

You're SOL. No way to remove it.

Better find out what part of your rig is allowing the interference to get into the recording, otherwise this will keep happening. I would guess a cable first.

I have never had this issue (knock on wood).

EDIT: I would also show your friend this website:

Very handy!

very funny - google maps...
He had a really old type phone at the time (has an Android now) and was calling from the road.

I have SP-CMC-08 mics, and a Blackberry cellphone..
Bad combination apparently. I now know they put out serious noise.
I always turn off the phone now at shows.
This happened last summer @ !!! in Brooklyn, out side show.


I just DL'ed a !!! show from TD and realized my recording is better.
I figured if I could fix the problem, I'd post it.

It's too damn bad, the recording is truly VG.
It was the 1st show with those mics. Who knew.

No more cellphone while stealthing ! period.
(and no, I don't record to the BB)

Depends on the type of interference.  Short clicks, you can zoom in on the clicks and get them out with a very quick volume envelope.  Or try a declicking plugin.  If that doesn't do the trick, try a spectral editor.  Of course any interference that is at a given frequency you can kill with EQ, but I am guessing this is loud broadband interference that is not periodic.  That can be pretty tough . . .

Yeah, I was going to suggest Izotope's RX. If anything can eliminate short bursts its that (once you get past the learning curve). It will still be a manual and laborious process though.

I have had the same thing happen to me with my SP-CMC-08. probably a bad cable connection or something

[igene]

They were BRAND NEW at the time.

Since then, I don't have the phone on, and there are no problems.
I see folks using phones near me, but I'm not affected.

As a matter of fact, I've made some of the best stealth recording with this rig.
CMC-08>CA-9100>VR-10

Thanks for the Izotope's RX suggestion.
I'm looking into it right now.
I've never heard of it, so 

I'll do a sample and post it in a few so you can hear the issue.

[igene]

here the sample.
I converted it to mp3 / 320Kbs for a smaller file.
The original is wave/16bit/44.1

it's not a complete song, just a partial with the noise and then a bit more for reference.

You always could use the other source for patches, if it cannot be repaired.


That's blackberry interference for sure, good luck!

[igene]

no other source. the other !!! show was another show, another location.
I never see them posted, so I DL'ed it to hear the quality.

My overall sound quality is better, but I won't post it with that horrible RFI.

I guess I'm boned !

I downloaded a free copy of Izotope's RX advanced.
It doesn't look like it covers RFI.

I don't think anyone does.
(I hope I'm wrong)

[Brian Skalinder]

In general, I think a flawed recording is better than none.  Sometimes not, though.  If the recording and performance are otherwise worthwhile, and no other recording exists, you could <1> minimize the negative impact to the listening experience by reducing the volume and intensity of the RFI, or <2> cut out the RFI and crossfade to minimize the impact, and post anyway.  That's probably what I'd do.

[Fatah Ruark (aka MIKE B)]

Great band.

If it's only in 5 or 6 spots I say just share it. Over an entire show that isn't a huge deal.

[igene]

did you listen to the sample ?

That happens 5 or 6 times through the show, but it lasts for like 20  or more seconds. each time.
and then repeats the cycle soon after.
there are many songs w/o it too.

I guess I'll try to fix it, but that's a bear of a job.

There's so much noise present in each instance of the RFI, it's a little overwhelming.

yes, you have to do it by hand in RX, there is no plugin to remove it. The reason I suggested RX is because it gives you a spectral view and allows the selection of sounds and harmonics in one shot.

I'll look at the sample when I get home and see if I can tinker with it in RX.

[Gutbucket]

The tools in RX are amazing (I haven't used RX but have played around with similar tools in Samplitude's Master Edition) but take both patience and skill to use effectively.

It may be helpful to consider that usually the most sucessful approach to noise-reduction is reduction, not total elimination.

My suggestion from a practical standpoint- if reducing the noise doesn't work (I haven't listened but I think it will be difficult) consider using a simple volume envelope to fade the program level down significantly just befor the events occur, then back up to normal afterwards.   The music will be reduced in level during these events as well of course, but at least the noise won't be shockingly loud, the fade down just before it occurs will give the listener a short 'warning' each time, and yet the flow of the music won't be completely broken as if there were a total dropout or gap.

[igene]

what's funny is I think the noise is AT the same level as the music, so that technique will not be helpful.
I appreciate the input though.

I use Goldwave, and I'm really good with it.

If I use that Software, and reduce each instance at the sine wave level, I think I'll go insane.
I've done minor fixes of DAT digi noise. That usually only happens 1 or 2 times and may involve actual program removal
and matching to the next good section of audio.
Sometimes matching time and cutting out a whole chorus to have it sound good etc...

This noise here is so interwoven into the music, it would take a solid week of work to fix.
I'm not sure I'm ready for that.

I'm uploading the show right now to MEGAUPLOAD and I'll post the link here.
I'll let you guys decide if I should start this insane project.
You basically should hear the whole show to put the RF noise into perspective.
