Tip #1 Fade Your Audio Clips
Adding a simple cross-fade before or between lines of dialogue helps reduce pops and clicks from a cut. They also help ease an audience in when a character is coming on and off screen.
Tip #2 Remove Clicks and PopsEven after fading your clips you might still find you have some clicks and pops that instead caused by a dry mouth. Don't be afraid to test out a Click-Remover filter on your audio and see if that gets rid of these offensive high notes that stick out in your dialogue.
Tip #3 Remove Hiss
We all love a good ASMR video every now and then but loud hiss in the background of a serious interview or dramatic scene is going to distract the viewer. You want the best SNR (Signal to Noise Ratio) possible, and removing this background noise will help your audience concentrate on the info you are trying to get them to notice... like the dialogue! A basic hiss removal plugin is a good place to start, or try your hand at a customizable noise removal plugin but be cautious when using one of these as they can often wreak havoc on other aspects of your audio.
Tip #4 Fluff Up Your Audio With EQ
Sometimes you just don't own the microphone you want to own. Other times you have an offensive location that's plagued with background street noise. Either way, doing an audio pass with an EQ Filter will help you sweeten up the sound just the way you like it. Remember though: boost wide, cut narrow. When adding gain to certain frequencies, make sure to use a wide Q. And when you are cutting an offending frequency, make sure your Q is set very narrow so you only affect the frequency you mean to and nothing more.
Tip #5 Room Tone Room Tone Room Tone
If you are trying to edit together a scene and have dead parts between lines of dialogue, you need to have a presence of atmosphere for the location in play. No room is ever dead quiet and room tone is to help cover these areas. Think of room tone like a bridge, spanning between the vast canyons on your timeline between clips with dialogue. Make sure you always record room tone! If you aren't sure how to record room tone, it’s simple. After a scene is over, keep rolling for 30 seconds and have everyone in the room stand still and very quiet. Now you have 30 seconds of "silence" that is nothing but just room noise. You can use this as a bandaid in post!
