I’ve also found that you can cheat a little at the beginning of the clip and reduce the volume of that part of the clip by Cmd/Ctrl + clicking on the volume path on the timeline and reducing the volume there a few dBs. Still not perfect, but much, much better. The beauty of this technique is that the effect is applied to the entire track so the analyzing happens just once at the very beginning of the clip. Here is the solution: Go Window>Audio Track Mixer and click on the little tiny arrow near the top, left corner of the panel to drop down the master audio effects for that audio track on your timeline.Ĭlick any one of the open slots for audio effects and choose Noise Reduction>Adaptive Noise Reduction and then use the little knob to adjust each setting as you wish and use the little drop down menu to access each of the settings we talked about above and tweak your Adaptive Noise Reduction. However! This is still a horrible problem when you have lots and lots of clips of an interview or spoken word lined up on your editing timeline because the effect is restarting and re-analyzing the audio every time you have a new clip and therefore you have a new, terrible, two second delay each time. It can be shortened to less than half a second at times. Now, to fix the two-second delay issue, I’ve found that the more I’m able to drag the Signal Threshold up (to at least 10dB) the much shorter the initial delay is for this effect. Avoiding extremes with any slider is usually a good mindset to have while working with this effect. The trick here is to tweak these effects until you get a desirable noise reduction. The FFT option is something called Fast Fourier Transform and it’s the range of frequencies that Adaptive Noise Reduction will examine.at the default of 100Hz, a window of 200Hz is removed and all other sounds, 100Hz greater, or 100Hz quieter will be safe and sound. Broadband Preservation: This essentially sets a window which Premiere Pro will target/remove.Setting this too long or too short can give strange sounds especially as your audio moves in and out of bits of speech, blasts of music, etc… Spectral Decay Rate: This is how long, in milliseconds, Premiere should hold the correction it is making before reverting to no adjustment at all.Signal Threshold: This is the level above which Premiere will not touch with this effect.Fine Tune Noise Floor: This is the level below which Premiere will reduce all audio to 0dB.Noisiness: This is the amount of original audio that we believe has the bad noise in it.Reduce Noise By: This is the number of decibels we’re going to reduce the unwanted noise.Here is a breakdown of the controls in this dialog box: Look to the Effect Controls Panel and choose the “Edit” button that has appeared with the Adaptive Noise Reduction effect. Look to your Effects panel and go Audio Effects>Adaptive Noise Reduction (the same process would apply for the obsolete DeNoiser, by the way) and drag that effect out onto an audio clip. We’ll fix that issue to the best of our ability right here, right now. The big issue is that almost always, the first few seconds of our audio sound like hot garbage. The filter essentially needs to “test” the audio track to figure out what it must remove. This is happening because of the “auto” nature of this effect. NOTE: This effect is famous for the “two-second delay” at the beginning of each clip on which it is used.

If you deal with sound, interviews, spoken word, or other in Premiere, you will find great value in this video. We will also FINALLY cover what all those sliders in Adaptive Noise Reduction are, how to reduce that annoying two second “Adapting” phase of the effect, and a super secret trick to applying the Noise Reduction to multiple clips without the re-adapting for each new clip. In this Premiere Pro video editing tutorial, we will dive into the technical side of reducing and removing background noise, background buzz, background hum, and any buzzing or humming sounds using the Adaptive Noise Reduction and shipping the audio track over to Audition for heavy duty background noise reduction and the seamless workflow of Premiere and Audition.
