Clean Audio in 2025: Pro Tips for Noise-Free Sound

How to clean audio in three simple steps

01
Import your audio or video
Begin by opening a new project and dragging in the file you want to clean. You can import podcasts, video clips—anything with sound. Once it’s uploaded, your next stop is the built-in transcript that maps each word to your timeline.
02
Apply noise reduction & audio enhancement
Locate the cleaning and mastering tools. Turn on features that reduce background noise and hiss, and boost speaker clarity. These may include advanced Dolby or Auphonic-powered settings like noise reduction, EQ, or dynamic range control. Adjust them to taste until you hear a more balanced, cleaner sound.
03
Review & refine
Listen closely for artifacts and tweak your loudness or compression settings if certain sections sound too soft or overcooked. If needed, remove filler words, or use AI to regenerate small segments for consistent volume. Once your track is crisp, it’s ready for export.

Keep it pristine: More ways to clean audio

Mastering with Dolby
For users who want full tonal control, advanced features let you push or soften frequency ranges, dynamically even out volumes, and squash unwanted noise. Keep it subtle—or crank it up if you want to be bold.
Auphonic mixing options
Use additional mixing modules to dial in better loudness, reduce crosstalk, and maintain consistent dialog levels even if your original recording has big volume swings.
Nip background hum in the bud
Whether it’s traffic outside or a low mechanical drone, the right noise cancellation feature helps you remove these steady hums and keep your dialogue clear.

More than just noise removal

AI-driven tools let you sculpt audio after you clean it.

Studio Sound
Elevate voices with a single click. It’s like putting every speaker in a pro recording booth.
Filler word deletion
Automatically spot and remove “uh,” “um,” and other stumbles. Helps your content sound more focused.
Regenerate rough spots
Smooth out weird gaps or fix low-volume patches by letting AI sample nearby dialogue.
EQ & compression
Fine-tune your mix with manual or preset equalization, then add compression for a polished, broadcast-ready sheen.
