How to edit noisy dslr audio
Hi everyone,
Recently,I did my first interview shooting with a dslr camera, using a lavalier microphone plugged directly into the camera. As I couldn’t monitor the audio, it was only later that I found out the sound was noisy. I believe I have set the sensitivity of the mic too high.
I also discovered the Automatic Gain Control, that can be really annoying! The noise becomes very loud when the person is not talking.
My question is… do you know the best way to edit this audio to minimize the noise?
Is it better to edit the audio before or after video editing?Than you!

I have had this problem on a few videos I have been editing in Premiere Pro recently. I came across the following guidance on how to deal with this issue, you may also find it helpful. https://www.trainingconnection.com/premiere-pro/lessons/noisy-audio.php

Never plug mics directly in to a DSLR camera. If you want I can expand greatly on this for you having learned the hard way!

The audio drivers in DSLR’s are rubbish for. You want to use an external recorder and sync it to the video afterwards. For clip mics I use H1 zooms. They are small and can go in the pocket of the artist. If you’re using overhead mics with XLR’s then you can use the H4n zoom recorder which also has phantom power. From there you can also take a line out of the headphone jack and into the mic input of your DSLR. Turn the recording level off auto to manual, and crank the level right down to one click above zero. You should then get a pretty good audio signal into your camera using the H4n Zoom as a mic amp.

But if your audio already has noise on it; Audacity (which is free) has a good noise reducing plugin.
The best is called X-noise which comes with the Waves bundle. It gets rid of ALL background noise. But it costs around $600 just on it’s own.
