Denoiser problem

Hi,

I've applied the denoiser effect to a number of clips to eliminate some hiss from an interview. (Need to match audio quality from a interview shot on an EX3 and then continued on a DSLR.) Seemed to do the job just fine until I played back the timeline. There is a lag in the effect as I go from clip to clip. Some of the audio levels start really low and then come up to normal, as if there's a delay on the effect. I've seen some old posts reporting this problem and am wondering if any of you can tell me if there's been any progress on a fix for this denoiser bug. Using Premiere Pro CS5 on a Windows 7 machine. Thanks.

    SOLUTION

    If the noisy clips are the only thing on that audio track, you can add the Denoiser effect from the audio mixer panel rather that applying it to each clip. The effect will apply to everything on that audio track, and I've found that it gets rid of the delays and oscillations of the Denoiser effect lots of times.

    Open the audio mixer panel and you should see a slider there for each track and a master. At the top left of the mixer panel UI is a triangle toggle like the ones on all of the bins in Premiere's UI. Use the toggle to expand the mixer panel to show the fx bus. There you can pull down a list of all of the audio fx to apply to each track. After adding an effect to a track, right click on it and choose "edit" to make adjustments. You can do this while your timeline is playing to hear the results. You can also keyframe effects on the timeline by setting the track display to "show track keyframes". That option is down on the audio tracks in the timeline panel.

    Since I learned of these options, I know find them indispensable and you them on nearly every project

    I have had so many problems with the audio in premiere that I gave up and went a different route. It can be fully reliable and then just horrible.

    Work Around

    1. Right click on the audio track > Edit in Adobe Audition. Premier will then render the audio and create a wave file for Audition. Audition will then open the file. It’s peaty seamless and a clean workflow.
    2. Edit the clip in Audition and just save the file premiere will automatically update problem solved. Plus Audition has much better tools for audio.

    I am also having this problem. I have tried everything in this post to no avail (except editing in audition). After removing all keyframe fades, moving effect to track level, clearing cache etc I have probably spent more time then it would have taken to figure out audition. Hopefully Adobe took note of the bug report and fixes this for Premiere CC. Any other suggestions out there?

      This it the Trick!!!  what a weird deal.

      I do think this BUG shoud be fixed..if it is. For me- when I added the denoiser to a clip and tweaked it to my liking, it works on the rendered video.  But when I export the sequence: each clip with the added denoiser effect starts off with no sound fix(hissing) and then it kicks in after about a sec or 2 and sounds clean.

      Filters make things easy. But I'm always gun-shy with auto "fixit" filters. We have not tested the audio denoiser filter in CS6, but I don't find the need too. In our small staff setup we try to find something fast, but not cut too many corners. We ended up creating two EQ presets for interviews with preamp hiss. If those don't work then we send the soundbites to Audition to remove the noise there. That's been a good workflow for us.

      I believe it has to do with audio level keyframes. At least when messed around with them it confused the DeNoiser filter. After deleting the keyframes or putting them on similar levels DeNoiser worked.

      I've had this problem and I had to clear my cache to get it to stop.

        Thanks for the reply. I found how to clean the cache but not clear it. Is there a difference? If so how do I clear it?

        There is no difference between them. If you clean it that is the same as clearing I just used the wrong word sorry.
