I stumbled on Izotope’s RX Audio repair tools a few years ago.
I bought and used RX5, and later upgraded to RX6 Standard. Things that used to be impossible to handle (such as wind noise, clothes rustle, echo or even police sirens) now could be.
I’m not an audio geek. But I do know that the best answer to all these audio problems is not to record them in the first place.
In other words, correct microphones correctly placed and a good audio environment are far more important than many people realise. And no matter the quality of the image, poor quality sound is unavoidably a direct index to one’s level of amateurism.
Even so, things don’t always go right. And that’s where RX6 Advanced is an essential editor’s tool. It’s pricey, but worth its weight in gold.
Now listen to me. RX 6 Standard is pretty good, but compared with RX6 Advanced it’s like the difference between a 2011 MacBook and a 2018 iMac Pro. Or, shall we say, a Ford F150 and a Ford F350 King Cab dually.
And the difference is a module called ‘Dialogue Isolate’.
Anyway, like I said, I’m not an audio geek.
I recorded the Duchess of Rutland in the Guardroom, which I already knew was an echoey space. I used a rifle and a lapel.
The rifle mic turned out to not do the job. And the lapel had clothes rustle on it. And, of course, there was echo.
Being the new and proud owner of RX6 Advanced I fully expected to use at least ‘Dialogue Isolate’, ‘De-Rustle’ and ‘De-Reverb’ to clean up the sound.
Turns out the default position of Dialogue Isolate did the whole job. It was a two click process. Sure, there were LOTS of parameters I could have adjusted, but just to show you what it can do in default mode using only the dialogue isolate module with no further adjustments, listen to this short excerpt. It starts with the untreated raw footage and intercuts with the RX6 Audio repair and graded footage.
Here’s the whole video.
