Background noise remover that makesa phone sound like a studio
Noise reduction takes out the hiss, hum and room tone. Then reverb presets and a proper channel mixer shape what's left — so footage recorded in a kitchen stops sounding like it.
How to use the background noise remover in three steps
Viewers forgive a soft image. They do not forgive bad audio — it's the single fastest reason someone swipes away. Most creators know this and still ship noisy tracks, because cleaning audio usually means exporting to a separate program. In Shorz it's a switch in the panel you're already in.
Turn on noise reduction
Shorz separates the speech from the constant background — air conditioning, computer fans, street hum, tape hiss — and pulls the noise down without hollowing out the voice.
Hiss · hum · room tone
Shape the room
Pick a reverb preset — Studio Clean, Podcast Warm, Small Room, Radio Announcer, Telephone/Lo-Fi and more — to give the voice a space it sounds like it belongs in.
Reverb & ambience presets
Balance the mix
Separate volumes for narration, main video, B-roll, music and sound effects — with hover previews so you can hear a channel before you commit to a level.
Five independent channels

Why Background Noise Remover in Shorz
Audio finished in the same app
No export to a DAW, no round trip, no re-sync. Cleanup, reverb, music, sound effects and the mix all happen in the panel next to your video — and the settings stay with the project.
No round trip
Free for everything except the cleanup
Reverb, ambience, the mixer, volumes and importing your own audio are free for everyone. Noise reduction is one of the paid features, so it's locked on free Auto Edit and Clipping runs — and runs on credits like everything else.
