In this insightful episode of Inside the Recording Studio, Chris and Jody tackle one of the most common challenges faced by audio engineers and producers: cleaning up unwanted noise in recordings. From vocal artifacts to background hums, noise can detract from the clarity and impact of your mixes if left unchecked. Join us as we explore the four main types of audio noise—non-musical noise, vocal noise, instrument noise, and audio editing noise—and dive into practical solutions for eliminating them before the mixing stage.

Episode Highlights:

1. Understanding the Four Types of Audio Noise: We break down the four main categories of noise that can creep into your recordings. Non-musical noise, like background hums or ambient sounds, vocal noise such as breaths and mouth clicks, instrument noise including squeaks and finger slides, and audio editing noise like clicks and pops from poorly executed edits. Learn how to identify each type of noise and understand the impact they can have on your overall mix.
2. How to Clean Up Non-Musical Noise: Discover effective techniques for reducing or eliminating non-musical noise in your recordings, from HVAC hums to environmental sounds. We’ll discuss the use of noise reduction software, including the popular iZotope RX suite, and explore how spectral editing can help you surgically remove noise without harming the musical content.
3. Addressing Vocal Noise: Dealing with vocal noise like breaths, sibilance, and mouth clicks is a critical step in achieving a polished vocal performance. Chris and Jody offer tips for reducing vocal noise using both software solutions and manual editing techniques. Learn how to use tools like iZotope RX’s De-click, De-breath, and De-ess modules, as well as manual editing in a DAW for more precise control.
4. Cleaning Up Instrument Noise: Instrument noise, such as fret squeaks on guitars or mechanical sounds from pianos, can sometimes add character but often need taming. We’ll discuss when to keep or remove these noises and how to use tools like EQ, gating, and even destructive editing to clean up tracks while preserving the musicality.
5. Eliminating Audio Editing Noise: Poor audio edits can introduce unwanted clicks, pops, or abrupt changes in sound. We’ll explore best practices for avoiding editing noise, from proper crossfading to using fade-ins and fade-outs, ensuring your edits remain seamless. Learn how to identify and correct problematic edits using iZotope RX’s Click Removal or traditional DAW tools like crossfades.
6. Destructive Audio Editing vs. Non-Destructive Editing: Delve into the debate between destructive and non-destructive editing in audio restoration. We discuss when destructive editing (editing the original file) can be useful for deep noise removal, and when non-destructive editing (editing with the option to revert) might be safer. Find out which workflow suits your projects best, based on the level of noise and the complexity of the session.

Whether you’re an experienced audio engineer or just starting out, this episode provides invaluable insights and techniques for cleaning up your recordings before mixing. From software tools like iZotope RX to manual DAW workflows, we’ve got you covered. Tune in now to Inside the Recording Studio and make sure your mixes are noise-free and professional-sounding from the start!
