How to eliminate hiss, hum and background noise for cleaner, more professional sound.

You can have perfect lighting and sharp visuals, but if your audio is filled with hiss, hum, or background buzz, your video instantly feels amateur. The good news is that noisy audio can be prevented — and fixed — with a few simple techniques.

This post breaks down the key steps I use in my own workflow. If you want to hear real examples and go deeper, watch the full video on HarvVideoAudioStuff.

Get Your Signal-to-Noise Ratio Right

This is the foundation of clean sound. Your goal is to capture a strong voice signal with as little background noise as possible. That means getting close to the mic, recording at a healthy level (not too low, not clipping), and using gear with low self-noise.

If your mic is far away and the gain is maxed out, you're not just boosting the voice — you're boosting everything else in the room too.

Proper Mic Placement

Where you place your mic has a huge impact. Too far away and the room takes over. Too close and you might get muddy low-end from the proximity effect.

Aim to keep the mic 6 to 12 inches from your mouth, slightly off-axis. It’ll help capture clear speech while avoiding plosives and unnecessary room tone. For lav mics, keep them free of clothing rustle.

Eliminate Unwanted Background Noise

Before recording, turn off anything that makes noise. Fans, fridges, buzzing lights, laptop fans — all of it can sneak into your audio. Even a phone too close to your gear can cause interference.

Do a quick check of your space with headphones and power down anything unnecessary. It’s a simple step that makes a big difference.

Improve the Room Acoustics

Hard surfaces reflect sound and create boxy, echoey audio. You don’t need a studio — even basic acoustic panels, thick curtains or rugs can help. If you’re working with a tight budget, cushions and blankets also do the job.

Small changes to your space can reduce reverb and give your mic a cleaner sound to capture.

Light Noise Reduction in Post

If you've done everything right and still have a bit of hiss or hum, tools like iZotope RX or Adobe Audition can help. Just don’t rely on them to fix bad recordings — they work best as a final touch.

Use them gently to preserve the natural tone of your voice.
