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

Same issue here. I've been spending the last 24 hrs trying to find a solution.

No.
I had the same issue with Audition.
You know the funny thing? I just had a chat with an Adobe Support representative and she told me the solution would be to use Final Cut Pro Instead.

Funny, huh?
I hope I receive an e-mail from adobe with a survey about their support.

Hi Senhay,

I looked at the bug and it keeps getting deferred because of a design limitation, apparently. It looks like a redesign of this effect will have to take place. I urge you to file a bug so that you can add your voice to the issue: http://adobe.ly/ReportBug

The workaround is to use Adobe Audition. Can you try that for now?

Thanks,

Perhaps the effect should be removed.

None of the suggested solutions worked for me. Even editing the sound track in adobe audition gives the same effect - first 2-4 seconds are left without denoiser.

Found a backdoor to this problem.

1) Export the audio with DeNoiser - Audio 1

2) Invert the audio. Export with DeNoiser - Audio 2

3) Import both Audio 1 and 2 and reverse Audio 2.

Audio 2 should have the effect problem at the end, not the beginning.

4) Now you can make an edit in which you can cut the problem out of your audio.

Cheers!

Hey everyone,

So I've tried applying the denoiser effect into the audio track like abrapiro14 said as opposed to applying it to individual clips but the exported versions STILL have the hissing at the beginning of each clip. Has anyone found another solution? Or maybe I'm not doing something right? It's driving me crazy.

I'm having the same issue. I've tried running the denoiser on everything, cleaned the cache ... but each time I cut to a new clip, I've got that hiss in the beginning. It's super frustrating and leaves my projects sounding unprofessional. Yikes.

Thanks abrapiro14 for the great solution! It worked perfectly for me….almost. Everything sounded fine on the export except for the very first clip, which still had 2 seconds of hiss. I found a workaround for this: If the audio track was cut (with razor tool) drag back about 2 seconds of the cut audio, set the volume level to 0 until your actual In point, and apply the Denoiser. The 2 seconds of nasty hiss gets applied to the silent chunk that you created, and your audio kicks in beautifully. Hope this helps somebody out there!

How is this still a problem? Seriously thought that with the new 2015 version that this would be fixed. This is embarrassing and is completely wasting my time trying to fix.

This thread was started in 2012 and the same problem still exists in 2015. Adobe you are a ridiculous company and your product management is a joke.

lmfao, late 2017 and I just ran into this issue on a 9 minute video with about 40 separate audio clips. I have never had a problem with Premiere in about 6 years until this, and I'm baffled as to how it hasn't been fixed in a handful of iterations. It's a built in feature that removes noise.....fix it!

Hi everybody,

I've had this same issue! I recently finished a 19 minute short film with hundreds of separate audio clips in it, many shot in different parts of a room with various noise levels. I added denoiser to all of the clips and adjusted each one independently for the best results, then I adjusted gain etc. so everything sounded perfect when I previewed it. I then encoded the video and almost every clip has a hiss at the beginning like a snake briefly and violently interrupting the dialog. I actually had to show the film live with this hissing because I ran out of time. How was I supposed to know that Adobe booby trapped this filter?

The thing I don't understand is why Premiere can't render out what it can easily play back in the audio preview. I've heard the buffer explanantion and I get it, but why can't Premiere draw from this buffer when it renders? I chatted with a tech today and he told me to just use Audition. Two problems with that: 1. I don't know how to use Audition and my film is already a week late, and 2. even if I learned Audition, that means I have to start over with my audio mix that I'm already very happy with and that took a a couple days to get right. NOT ACCEPTABLE ADOBE. The tech said that they're working on a solution, but after some searching online it appears that this has been a problem since 2006. I guess they're just taking their sweet time.

Here's my solution. It's not pretty but it appears to be my only one at this point. I'm going to record the good preview audio with Soundflower on my mac and then import that into the project to replace my original files. I'm probably going to lose some audio quality doing it, but I'll take that over random audio hissing destroying my film any day. I'm going to try it tonight and I'll let you know how it works.
