Surround denoiser

Hi everybody,
I'm looking for a surround plug-in for noise reduction (5.1, or even 5.0).
I'm currently editing some recordings in that format, and both Izotope Rx or the Steinberg's nise reduction plug-in are stereo-only.
I've scouted the web for info but with no luck.
The only software explicitely advertised as surround capable seems to be Spectral Layers, but it''s really out of my budget.

Any suggestions ?

Don't stereo denoisers noise-print each channel individually anyway ? And would they do anything else ?

tanx for answering !

@Airon: sorry, I dont' get your answer, could elaborate a bit more ?

@ErikG:
I've omitted that I currently use Nuendo 5.5

I may be wrong, but as far as I remember (had this in previous occasion, but it was just fun sessions) the Waves denoiser will not work in multi-mono mode in Nuendo, like it probably would in PT.
It will just denoise the first two channels, leaving the rest untouched.

So, to refine my question, I'm loooking for a denoising plug (or routing) that will allow me to work on multichannel files in Nuendo.

(Splitting channel in separate tracks is not really an option, cause it would mean to re-load all the files, and do the editing again....please no....)

tanx !

What do you mean re-load the files? You can use your existing, pre-edited multichannel tracks, split them into mono tracks, (which could take a while, depending on how much material you're dealing with), but then you could consecutively select all the mono channels of each file, apply the same de-noising processes to all 5 or 6 channels (I suppose this is what you want to do), continue on till you finish with all the material, and then re-combine into multi-channel files once you're done..... All the edits would stay intact, no?

Hi Danijel, thanx for joining
I'm new to Nuendo and I didn't thought about that possibility, sounds extremely rational !

At the moment I've place a 4channel audio file, recorded with a Soundfield mic, in a 8.1 music track (as suggested on the Soundfield manual)
I just wonder if the decoding plug-in will work fine if placed on a surround bus, where the separated tracks will be routed.
Otherwise I'll re-encode the tracks when finished with denoising.

Tanx for suggesting a practical solution.

I just remain curious about the possible existance of a dedicated multichannel denoising plug-in....
seems quite a simple option /feature to me for a very used process in any post-audio situation, but maybe I'm just missing something

What type of material is it?
Typical soundfield recordings are ambiances and I personally avoid using noise reduction on ambiances I'd prefer to use careful EQ sculpting to lessen any noise.
Also make sure you decode the 4channel recording into your destination format before applying any processing or the decode won't work properly an it will probably get quite weird.

I'd be using the method of splitting the material to mono-tracks as well, because denoisers do not seem to care about a relationship between channels.

To be perfectly honest though, I've never denoised my stereo ambience recordings, though I do sometimes multi-band gate them(via C4/6 or Wavearts multiband) to get at specific sounds.

If Nuendo can send to four mono tracks for a quad recording, you can denoise in there with plugins on the insert, be it the CPU-heavy Izotope RX2 d-mode, the CPU-light Cedar/WNS plugins, multiband gates or even just EQs.

@ ErikG:
the recordings are mostly impacts with long and sustained reverb tails,
I'll try to split the 4 track and re-encode them after cleaning, should work

@ airon: do you mean sending the 4 track separately to 4 mono bus, denoising and then back into a quad track ?
I don't think it's possible in N5, but it would be great to be wrong

If you want to clean it online (via insert plugins) you can simply insert two stereo denoisers on a quad track, and route one of them to work on the latter two channels.....

@ danijel: it worked perfectly in nuendo, tanx a lot.
I wasn't aware of the plug-in routing feature, tanx for suggestion
