Audio cleanup

Where Video editor › Audio, or Home › Open a tool: Audio cleanupCost 10 credits a clean; silence and filler removal free

Audio cleanup fixes the sound of a recording. Each tool processes the clip on Muvomi’s servers and saves the result as a new clip. You compare Processed with Original, then keep it or discard it. Your original recording is never changed.

Clean a recording

1. In the video editor (with AI mode off), select a video or audio clip, then press Audio in the tool row.

2. Choose a tool and, where offered, a strength: Light, Balanced (the default) or Strong.

3. Press the tool’s button. It shows Processing…

4. Press play and switch between Processed and Original to compare.

5. Press Keep this version, or Discard.

Undo restores the original afterwards.

In AI mode, just ask: “Clean up the audio”, “Remove background noise” or “Remove hum”. These exact phrases run the tool straight away and cost nothing extra. See Free commands.

The tools

Tool	What it does
Noise cancel	Removes hiss, fans, air conditioning and room tone. Strong also quietens the gaps between phrases.
Voice enhancer	Adds clarity and presence, tames harsh S sounds, and evens out the level.
Studio sound	One step: reduces noise, balances the voice and sets the loudness.
Level loudness	Brings quiet and loud passages to an even level for online video (about −14 LUFS).
Remove hum	Removes 50 and 60 Hz electrical hum.
Reduce reverb	Lowers the room echo that rings on after words.

Tighten the talk

Two more tools shorten speech, and they’re free:

• Remove silence finds pauses longer than about half a second, keeps a short breath on each side, and removes the same time from every track, so the picture, sound, titles and captions stay in step.
• Remove filler words cuts um, uh, erm and hmm. It reads the clip’s captions, so caption the clip first.

Both show their cuts as With cuts for you to compare with Original before you keep them. Each pass makes up to 24 cuts.

Cost

Each of the six cleaning tools costs 10 credits, and a clean that fails is given back. Remove silence and Remove filler words are free (filler removal needs captions, which are a captions job if the clip has none yet).

Limits

• One selected clip at a time, up to 100 MB.
• The tools reduce steady noise. They don’t remove sudden sounds like a door or a horn, other voices, or music under a voice.
• Filler-word removal is written for English.

Tip

Clean the sound before you add captions and cut the edit. Cleaning never changes a clip’s length, so captions and cuts stay aligned either way.
