NR2 question

williamk wrote on 9/23/2006, 6:29 PM
When you are capturing a noise print we take .005 and then it runs through and removes the noise. We then save it as a wav file but then it doesn't replace the original. to do so ourselves will not ensure the video and audio match.

Question is after we render can we run the NR through a loop to capture only the parts that we want the noise to remove and is there a step by step way to do the capture, process, save, replace.

And is using noise reduction throughout the entire project after rendering okay or will that screw things up. Time is not important.

Thanks

As far as the render, you can run NR as a live/realtime plug on a track, even running more than one instance.
However, I generally do my NR work in Sound Forge, and allow Vegas to create a "take" of the audio, so that it's always in sync, but the original is always available. If you have Forge, simply right click and choose "Open copy in Sound Forge" from the Vegas timeline. Do your NR work there. Easier, just as fast if not faster, and easier on the CPU if you have a lot of content on the timeline.

I hope I can ask this and not get "shot down." I'm not knocking NR2 at all. Wonderful tool. But I've used (in a VERY limited way) the noise reduction built into Audition and it seems ("SEEMS") to rock!!! Easier and more powerful than NR2 by a long shot.
Now, this could just demonstrate my lack of knowledge of NR2, but is it as far behind as it appears to be? Will there be an NR3 sometime in the near future? I've had my version of 2 for a really long time now.

I've wondered the same thing. Back when Auditon was Cool Edit the noise reduction seemed to work slightly better with the default settings. I never did any specific tests, but just from basic impressions I always felt like Cool Edit provided a file with less noise and artifacting in the end.

However the two noise reduction tools were close enough to each other in qualithy that the convienence factor of using NR2 in Vegas caused me to eventualy stop using Cool Edit all together. I don't know if Audition made any improvments over Cool Edit or not.

It would be nice to know if the Sound Forge guys are keeping an eye on the technology to know if we have the very best noise reduction available.

The silence is a little painful. I'm so rooting for Madison product, it's tough when there's no word on new light. I've worked with Audition only a little, but the hype of being able to clean up the audio using visual cues LOOKS amazing. The tool itself appears to be much more deep. I'm also really bad at audio clean up and the Audition tool was a bit more intuitive and I had good results with it more quickly than I ever have with NR2. I'm just hoping Sony puts out a newer version that more directly competes with Adobe. Who wants to go that route?

I've pretty much tried all the noise reduction plugins (except for the new Waves Z-Noise) and the Sony NR plugin works much better than all of them. Just make sure you select "Mode 3" to keep the artifacts to a minimum.

Yeah, the "rules" as I understand them are:
Take REALLY small sound bites
Use Mode 3
and don't try to reduce the noise in one shot; get rid of it incrimentally.
Anything else I should know?

Take new samples between the increments.

Name and SAVE your profiles too - even for a tiny subproject. I've often left a "good" result to memory - and it has failed me. Name and Save.

Also if you've got a rough idea of where the noise lies you can edit the noise profile to ensure nothing wanted gets harmed. Try drawing a small box in the profile window to edit sections of the spectrum, works well.
