The problem
Audio is the half
most creators
underestimate.
Your viewer tolerates shaky footage. They won't tolerate audio that's too quiet, too loud, hissy, or boomy.
The fixes traditionally require audio engineering knowledge. Learning those tools takes weeks. Applying them per clip takes hours. Sapari's Clean Sweep runs all of it in one pass, tuned for talking-head content.
Match platform standards (YouTube -14 LUFS, broadcast -23 LUFS).
Cut hiss from a cheap mic or hum from a laptop fan.
Even out quiet and loud moments.
Reduce boominess or room echo.
What it does
Three passes.
One toggle.
FFT subtraction
Samples the ambient noise floor and subtracts it from the speech signal.
- · Laptop fan hum
- · Air conditioner drone
- · Mild room hiss
- · Background keyboard clicks
EBU R128
Targets −14 LUFS — what YouTube, Spotify, and most platforms expect. No more "why is this podcast quieter than the next one."
Speech on top
When you layer asset audio (music, sound effects), Sapari manages the mix. Optional automatic ducking during dialogue.
Where it won't save you
Honest about the limits.
Clean Sweep is tuned for talking-head content recorded in normal environments. It won't fix:
If your raw recording is unusable, no algorithm fixes it — record it again.

On for the project. Applies to every clip.
Most creators don't want audio engineering — they want clean audio. Mode-level controls (conservative / balanced / aggressive denoising) are on the roadmap.
In the pipeline
Runs before transcription.
Clean Sweep runs on every clip in the project before captions and before silence detection, so denoised audio gets transcribed instead of the noisy original.

Common questions.
Will it make my voice sound robotic? +
At default settings, no. The denoise threshold is tuned to preserve speech transients. If you hear artifacts, it's usually because the source recording had close-to-speech noise — in which case you're at the limits of what any tool can do.
Does it boost my voice volume? +
Normalize brings perceived loudness to platform standards, not raw peak volume. Your voice sounds consistent across your channel even if individual recordings were uneven.
What about music beds? +
Asset audio (music, sound effects) mixes with speech. Optional ducking lowers music during dialogue automatically.
Does it work on non-English audio? +
Yes. Clean Sweep is language-independent — it processes waveform, not words.
Can I turn it off per clip? +
