Michael Stahr Posted March 15, 2017 Report Share Posted March 15, 2017 Cedar DNS II, I have had the pleasure of working with mine for 6 months now. Interesting that the DNS does not stand for Dynamic Noise Suppressor. Though it is Dynamic, the DNS II is a Dialog Noise Suppressor. In the right hands it is a wonderful tool for some things – in the wrong hands, well let’s just hope the wrong hands can’t afford it. Agreed, it does not at all remove the need for professional audio post – just too many subtleties that can not be addressed in real time and in the field. This is, in my opinion, not the responsibility of the Mixer. The DNS II lives alongside my SD 688. The excellent routing abilities of the 688 allow me to quickly choose what is being processed and then record the result on the last two tracks, in real time. All sources are ISO’d for the post purists. In addition, I am able to send what I call, “Quite Tracks” to camera and to Comteks. If the client needs minimal post they can use the QT’s. Their choice. Everybody gets what they need - but, and this is a big one, except the Mixer, still have not found anybody that wants to pay for it. They like it, want it, don't want to pay for it. However, they do keep calling. Can that make it worth it? One thing that has not really been talked much about is that the Cedar is not an either on or off device. You can ‘dial-in’ the amount of NR. The continuum runs from none, to quite pleasant, to ‘unnatural’ and on to irritating. For example, if the room has a overpowering echo, you can dial some of it out. But, if too much echo is removed it doesn’t sound like the room at all. One more tool to help with the mix. Pleasant NR sent to camera and Comteks helps make the mixer sound like a hero. Oh, and for live, since you are only sending amazing audio, you are an unknown hero. One more example for, “the better you do your job, the less anybody notices.” One small caveat – when monitoring the quite tracks I am sometimes asked, “Did you hear that??” The Cedar really is that good, I just worry if they think I can’t hear that well… It does take some time to get the hang of it. I haven't found much for training, and the controls are not all that intuitive, so give yourself plenty of time to train yourself.

Henchman Posted March 16, 2017 Report Share Posted March 16, 2017 I use the CEDAR on the dubstage. It's the only noise reduction plugin I'll use on Dialog for broadband noise reduction. Quote Link to comment Share on other sites More sharing options...

It's the only noise reduction plugin I'll use on Dialog for broadband noise reduction. Sure. What do you think about getting tracks that have already been noise-reduced? My "sense of the meeting" is that it seems like PSMs who can afford this box are going to use it, on their mixes anyhow....the response here and elsewhere has been very positive. So, given that, would there be interest in an 8 channel version of this? 16 channel? Quote Link to comment Share on other sites More sharing options...
Henchman Posted March 16, 2017 Report Share Posted March 16, 2017 No. Do not process tracks going to post. Period. Quote Link to comment Share on other sites More sharing options...
soundtrane Posted March 16, 2017 Report Share Posted March 16, 2017 One can always record unprocessed tracks - it's the world of multitrack digital recorders... Quote Link to comment Share on other sites More sharing options...
Wandering Ear Posted March 16, 2017 Report Share Posted March 16, 2017 With ever increasing track counts already, I think there would have to be a lot of benefit to doing the processing in production and doubling the track count to record unprocessed and processes. The trade off is a lot more time in post managing tracks, choosing which version to use when etc. Seems like that would waste as much time as it takes to just do the processing in post. Now if the noise reduction box had a way that worked significantly better in the field than in post, like mics in the room dynamically processing the background (hypothetical of course), then I could see the reason, but until something like that comes around, double tracking everything seems like more trouble than benefit. I haven't used the DNS though, so I'm just speculating. Quote Link to comment Share on other sites More sharing options...
Jeff Wexler Posted March 16, 2017 Report Share Posted March 16, 2017 I think the general approach in production will be to utilize the Cedar DNS 2 on the mix track only, leaving any and all of the iso tracks unprocessed and available for post to work on if needed. I really don't see production sound mixers applying noise reduction on all tracks which would produce, as you have said, multiple tracks, processed and un-processed, it could be a real nightmare. One of the most useful aspects of the Cedar box that I have heard from people using it, is to improve the mix track even for the benefit of those needing to monitor in real time on the set. Following that, it could give the picture editor a cleaner track to work with before sound editorial gets their hands on your mix and the isos.

Matthias Richter Posted March 16, 2017 Report Share Posted March 16, 2017 benefits of the DNS2: cleaner Mix-track for use in editorial, dailies, screenings for producers, test-screenings etc. - all happens several month before audio-postpro touches the unprocessed audio from the isos cleaner Comtek-feed for director and last but not least: cleaner mix to MY ears. It´s a relief believe me. Have been shooting with 2 Alexa65 for 90 days now I know my ears and nerves would have suffered way too much without the help of the Cedar. These cameras are pretty noisy since the second fan for the DSP is not going low in rec-mode. Without the DNS2 I only could have hoped / imagined that post-production will denoise my audio and safe the performance. By using the DNS on set I know ON the day, that my audio will be usable. Post might / will go again and use the isos to start with but this is several month ahead. Got a call in the beginning from the editor complaining about the noise floor. He was NOT using the mix-track but tried to build his own mix from scratch. I told him to do himself (and me) a favour and to use my mix. Haven´t heard from him since (well that might be for other reasons - hope not). Quote Link to comment Share on other sites More sharing options...
Wandering Ear Posted March 16, 2017 Report Share Posted March 16, 2017 I didn't consider using the DNS to help you set a threshold for what post can and can't easily take out later. Basically a live audition. That could be very handy. Quote Link to comment Share on other sites More sharing options...

Philip Perkins Posted March 16, 2017 Report Share Posted March 16, 2017 If the DNS 2 can help you sell the on-set audio via IFB etc that's cool. I went through a period many years ago where we used expanders on the set in the same way some of you folks are using the little Cedar--esp re camera and BG HVAC etc. One caution I learned from doing this was that it can be easy to 1: mask issues in your monitor mix that you might could deal with directly (by turning stuff off, barneying cams etc) and 2: make assumptions about how post will go and what their taste might be (given the rest of the soundtrack components and the edit) about all this, that can turn out to be incorrect, and 3: slip into having the thing on all the time, and maybe in the heat of things succumbing to the temptation to push it a little too hard. Re: the concept of showing post and production what can be done with the tracks re: NR, sometimes it is actually important that the editors hear all that the posties will have to deal with in the dailies, instead of having that possibly be a surprise when the isos are finally listened to.... Finally, know that NR in post is done track by track (much of it by sound editing + mixing as opposed to signal processing), not on an overall mix, so the "modeling" aspect of the NR for post doesn't really work very well.

ivanovich Posted March 17, 2017 Report Share Posted March 17, 2017 lots of interest things being said here. Henchman, when you say you use Cedar do you use the plugin or the DNS2? It seems like you could also use it as a hardware insert in a post room setting. Anyone out there using it in the control room? Seems like a plush tool to have. If I had it I would definitely use it when called for. I think its great that you could take it to the control room. I end up doing some post work and use Izotope RX5. I'm sure it sounds different.

Philip Perkins Posted March 29, 2017 Report Share Posted March 29, 2017 So here's another location Cedar angle: a venerable DNS1000 working on an interview location equipped with The Devil's Own HVAC. The director is an ex-soundie and warned me the day before, so I worked over the Comtek feed with the Cedar to keep the creatives from panicing. A clean (ie dirty, non NR'ed) track was also recorded. Happy with how one can easily do a digital loop-around with the 633. Quote Link to comment Share on other sites More sharing options...
stevegrider Posted April 2, 2017 Report Share Posted April 2, 2017 I bought a DNS 2 shortly after it's release. I never have used it for the entire mix, what I have used it for is to turn my Sanken CS3e into a "Super Sanken CS3e". I guess I treat it more like an EQ knob for a boom channel than I do a final mix solution. I must admit that I have come to use a light touch, and I don't really push the limits of it's capabilities. Not every set is problematic, and location tracks shouldn't be sterile. I give post Deva files with two boom tracks (a processed and then a clean track), and they can use what they prefer. The processed boom track goes into the mix track. I have used this box this way on several projects including two lower budget features, and it's use in this way has met the approval of post so far. There have been times where it "saved the day", I once was hired to do an stand up interview on a factory floor, and the Cedar made an unusable situation usable. The client was willing to pay an extra $100 to me as not go to audio post for one shot. It small enough live in my bag, but it doesn't, it lives on my cart. My cart kit fee went up $50/ day after it's purchase, and my "cart clients" didn't seem to mind. My "bag clients" are a little more thrifty, and sometimes they need a Cedar too, but are less willing to pay for it, or have access to post plug-ins themselves. It is one more tool in the toolbox, my ledger book says it hasn't paid for itself just yet, but I am glad I have it. Quote Link to comment Share on other sites More sharing options...
tom williams Posted April 2, 2017 Report Share Posted April 2, 2017 HI Steve, Interested in your routing the Cedar to the Deva. Thanks, Tom Quote Link to comment Share on other sites More sharing options...
stevegrider Posted April 2, 2017 Report Share Posted April 2, 2017 Signal cames out of my Lectro RX (wireless boom) into an XLR Y cable. The two males go into each channel of the DNS2. Channel 1 of the DNS2 (the channel I dial up the FX on) then goes into the boom channel my Cooper 308, then sent pre-fader to channel 2 of my Deva and labeled "BOOM DNS2". The signal in channel 2 of the DNS2 is run through unaffected, and is sent directly to channel 3 of the Deva, and simply labeled "Boom". I have the Deva on channel 3 set so I can control the level on the machine knob rather than the console, it frees me a fader on my 6-strip board. This way I can dial in the FX of the boom signal I am sending through the console to the mix on Deva channel 1 and have it iso'd on channel 2. I am also sending a clean boom on channel 3 should edit rather use it instead. Does that make sense the way I wrote it? Sometimes I'm not the best at this.

Philip Perkins Posted April 2, 2017 Report Share Posted April 2, 2017 I like the idea of the "light touch". On most of the demo videos I've heard of the DNS2 sounded like it was being pushed too hard (to show the diff I guess). The NRed sound sounded processed--tubbier, missing life in the top end. I'd rather have a bit more BG noise with less of those artifacts, which knowing Cedar I'm sure is very possible. I had an email exchange with Gordon Reid from Cedar, and learned (as those of you using the box already know) that it can stay in "learn" mode to deal with dynamic BGs. All right, Cedar!

stevegrider Posted April 2, 2017 Report Share Posted April 2, 2017 I know I don't use this unit to the fullest extent of its capabilities in the field. You could say that I use it more for a "digital EQ" to roll out things like bad HVAC and traffic on my boom channel. Quote Link to comment Share on other sites More sharing options...
tom williams Posted April 2, 2017 Report Share Posted April 2, 2017 Hey Steve, Got it, that certainly is one way to do it. Was wondering if you brought the boom signal into you board and then sent to Cedar with a send then bring back into Deva on a return.

Michael Stahr Posted May 28, 2017 Report Share Posted May 28, 2017 Light touch - absolutely. It can be fun to 'show off' the Cedar capability - but I try to be careful not to remove a person from their environment. As for Routing: Flexibility is key. Since I don’t use the Cedar for the whole mix, I get to choose which source will be sent to each of the Cedar’s two channels. I use the very flexible routing of the Sound Devices 688. Most of the time two mics are to feed to the Cedar. The SD688 Aux Channels 3 & 4 are cabled to the Cedar. The output of the Cedar is cabled back to mixer inputs 11 & 12. To choose what is being fed TO the Cedar, open Aux Output 3 and choose which channel to route. Often I send the Boom (my channel 1). It is always sent Pre Fader. This means the Mixer Ch 1 trim pot is the adjustable input of the boom to Cedar. Mixer channel 1 is ISO’d, unprocessed and could (but doesn’t have to be) added to the Mix. Channel 11 (also ISO’d) is what I call "QT-Boom". When only a single boom is being recorded, it is sent to BOTH Cedar channels. You now have 3 boom tracks: Clean, QT-light & QT-heavy. Ok, ok this is giving post too many choices but remember Flexibility... If a Mix is required either ch 1 or ch 11 (never both) can be used to build the mix. With single person interviews, split tracks of Ch 11 (QT-Boom) and Ch 12 (QT-Lav) are sent to camera. "Quite Tracks" are always sent to Comtek and to Transcription. All this routing is done without moving a single cable. M* Quote Link to comment Share on other sites More sharing options...
