Noise reduction not applying to beginning of clip

There's a bug in Premiere Pro which results in the hiss reduction or certain audio effects not being applied to the first 2-3 seconds of audio when exporting.

After looking this up on the Adobe forums I found other people with the same issue, and they were advised to edit the audio in Audition and reimport into Premiere Pro. I am having the same problem in Audition however.

I capture my noise profile, apply the adaptive noise reduction (or dehiss or whatever) and the audio sounds fine in the program. But when I export the first 2-3 seconds have the original hiss and you can then hear the effect kick in.

Can anyone help?! I offered to start doing video for my work and this is driving me up the wall.

    For anyone needing help with hiss in Adobe Premiere CC 2017

    1. Apply Adaptive Noise Reduction

    2. Fix audio to your liking

    3. To get rid of the hiss that still remains in the first two seconds you first need to make the clip a little longer at the beginning and then go under Effect Controls and scroll until you find Audio Effects: volume, then add a key frame at the beginning of the clip where you will adjust the level to -10 (or whatever level works for your project) and then add another key frame where the hissing eventually stops in your video and bring the noise back up to 0 with that key frame.

    I've been doing this with all my audio that needs it and this has worked like a charm for me. I hope this helps you!

    Here's an easy fix.

    1. Export the bad audio as a WAV file (in my case it was the entire video).

    2. Import WAV into Audition

    3. Choose: Effects - Noise Reduction - Adaptive Noise Reduction - Play with the settings until you're happy.

    4. Export the audio as a new WAV file.

    5. Bring new WAV file into Premiere and replace the problem audio.

    Would be great if the effect could be applied in the same way as color to masterclips in the source panel so to affect all clips used in sequences.

      I must agree. ANR is not a tool I use at all to fix noise anymore because in the real world where I do my work and shoot the realities are much different. I always go directly to audition. I have tried every which way to get that hiss out and it does not work. So its not a bug then it is flawed design work. Take from some who has been software developer. I am a big fan of premiere just not this tool. To me if audition works better you will always go there because you will want to deliver quality work and not spend time trying to figure out to get ANR to work better or just you workflow to function within ANR. I think adobe should stop ignoring its customers and make it the way we want it because we are paying for it.

          I found another way that I find works best for my videos to get the Hiss out of the Adaptive Noise Reduction at the beginning. Here are the steps:

          1) Add Adaptive Noise Reduction to the clip

          2) Add Constant Gain at beginning of the clip; a time length of (00:00:00:10) should do

          3) Go to Effect Control and click on the clip you added Adaptive Noise Reduction on and go into edit.

          4) A window will pop up saying Clip FX Editor. You can leave the Adaptive NR preset on Default

          5) Increase the Signal Threshold from 0 to 10... (and can play around anywhere above 0 to get rid of the hiss at the beginning)

          Hope this works for you

              I've tried all of these and nothing works. If I extend the clip, the audio fixes to where I need to, but then when I try to keyframe the part at the beginning that I have no use of, it just brings back the hiss. It's ridiculous! How come it's taking Adobe so long to fix this when every other noise reduction feature has been rendered obsolete? I get that they want to push Audition, but come on, one working noise reduction function on their video editing platform is kinda necessary!

                There is nothing for Adobe to fix as that's just the way that Adaptive NR works. If you are using it in the Multitrack view Audition just applies it in real time as you play the audio. So what it does isn't locked in to the file when you change the keyframes since the Multitrack view is non destructive. There are a couple of ways to make this work in your scenario. Either apply it destructively in the Waveform view and save the NR audio as a new file or mix it down to another track in the Multitrack view.


                Why would they think you'd want the beginning of the file to be jacked up? I just dont get it. I ended up extending the file, exporting, importing back in, then cutting the extended bit. Huge pain but works. Not impressed considering its 2017. Thank you so much for a quick reply and willingness to help though. You are appreciated.

                I know I'm a little late in replying, but I just experienced the same problem and came up with a solution. If you have a few seconds of audio before your intended start point, you can apply the ANR effect, render and replace the clip, then cut it down to the desired start point. Hope that works for you.

                  Adaptive Noise Reduction is just that - adaptive. It identifies sources of dynamic noise over time, then reduces them.

                  If your clips don't have a few seconds before the in-point with which to apply the algorithm, you can often just copy/paste a few seconds at the beginning of your recording, run the effect, then delete that section. Dropping a marker after you paste the selection (while it's still selected) will make it simple to select that range again for deletion.

                  Otherwise, you might want to try the more manual NR tools. You'll have more control over what's identified as noise and how drastically it's reduced, and can make several light passes for better results.

                  Thanks, I will try the pasting suggestion.

                  But although I mentioned Adaptive Noise Reduction, it doesn't matter what effect I use – it's still not being applied to the first few seconds of exported audio.

                  Pretty terrible bug given the amount I'm paying to Adobe each month.

                    It certainly happens with ANR, and the reason is explained above. But I've never had this problem with any other effect, and if this really was an issue/bug it would have been mentioned more than a few times before. And I'm afraid that it hasn't been...
