Audio engineers have been creatively trying to remove noises from music and dialogue tracks with various tools such as equalization, noise reduction, and creative techniques for phase cancelling. Recently, I purchased iZotope RX 4 Advanced software, after I’d seen the power and possibilities. Its ability to remove noise, such as hums and buzzes, take out reverb from poorly recorded tracks or from tracks recorded in bad environments, and to literally PhotoShop out sounds from a visual audio spectrum, is absolutely amazing! I was able to experiment on several different types of audio clips, such as a badly recorded guitar in a live session, dialogue from a documentary with multiple air conditioners in the room, and even an interview in a reverberant space. It was almost a miracle!
Nothing is for free, and there are always artifacts to deal with, but the tools available in the software don’t even come close to the old days of tweaking equalizers and playing with notch filters. It was well worth the price to purchase this, and what I can offer my clients with speed and sonic clarity will make my post-production craftsmanship even better.
I’m not selling this program and I have a lot to learn, but so far, I like it! You can check it out on your own; go to this link: https://www.izotope.com.
