An Intro to Noise Reduction - Droneward Bound - OFFICIAL DISCUSSION


It’s important to know what the current tools available for audio repair can do, and what they can’t. This makes you more prepared on set, and allows you to make informed decisions about your sound recording situation– what is acceptable, what is a real problem, and what can save you time or ultimately hurt you later on in post. In this tutorial, Kevin Senzaki walks us through the audio repair we had to do on our short, Droneward Bound.

We were already big fans of Izotope’s RX4 audio editor for audio repair, which is why we’re thrilled they are supporting us. Check out their new update, the RX5, here.

We encourage you to play around with different tools available to you and to learn the weaknesses and strengths of the software you have available– you don’t need expensive programs to keep yourself informed, problem solve, and to be creative when capturing sound. While we focus on RX4 in this video, we hope that it gives you a better understanding of how audio repair works and its capabilities in a broader sense, and that you can apply that understanding to the tools you have available.

Wondering just how bad the location sound really was? You can watch the whole short with untouched, original production audio here!

Special thanks to RØDE Microphones! While we tried to make our sound as crappy as possible in this short for educational purposes, their mics still performed above and beyond.


I saw an Izotope rep at a editor’s meetup a few months back and since then, I’ve loved using it. Very powerful stuff and has saved a ton of “bad audio” I’ve received.

Great video too btw! :smiley:


Hi guys ! Glad to learn about Izotope, that’s pretty cool ! To the scene on the beach, you had some wind. Usually, when I got wind like you, I use a “Low Cut” or “High pass” and I delete 250Hz, it cut really good the wind and don’t affect too much the voices or other sounds ! That’s my tip for you guys ! You probably already know that tip I guess ^^

I’m learning so much with you looking your great videos !


For all my CC users out there, one can do almost everything shown here in Audition, including the Photoshop-esque controls. You can even dynamic link from Premiere! I had to use it a ton for a project over the summer when my Lav+Recorder files were corrupted and I needed to clean up the sound coming from the backup Videomic on my camera.


Tutorial was superb, but holy hell that short was brilliant!


That’s definitely something you can do on-set (some mics and some recorders will have low cut/high pass features built-in), and my dialogue edit tracks always include an EQ with a low cut as well. I was considering going into EQ to remove low rumble, but I decided to leave it out of this specific video to avoid complicating what’s hopefully a pretty basic/straightforward explanation. But point being, yes, there’s always more than one way to tackle a problem!


Where would one find those settings? I’ve been playing around and can’t seem to find what I’m looking for. Pretty new in the game of audio.


My heart skipped a beat when she was putting the inspire down in storage mode; I didn’t immediately realize you had taken the camera off. What a great little short!
