# Voice Cleanup (Sashimii Docs, Editing) > Clean up background noise and room echo in your voice, preview the result against the original, and choose how much to apply. Canonical: https://sashimii.app/docs/voice-cleanup/ Last updated: 2026-11-02 Voice cleanup reduces background noise and room echo in the recording, on your Mac. It is on for new projects, at Amount 75%, unless you untick **Clean up voice** at setup. The transcript and the waveform always use the original sound. Open it with **Audio** in the toolbar, or **Cut › Voice Cleanup…** (⌥ ⌘ V). The Audio icon shows whether cleanup is on. ![The Voice Cleanup sheet: the on and off switch (1), a 30-second preview window over the recording's waveform (2), the Amount slider at 75% (3), Listen to Cleaned or Original (4) and the Apply button (5).](https://sashimii.app/_astro/voice-cleanup.BsQ8YiTo.png) 1. **On or off** for the whole project. 2. **The preview window**: 30 seconds of speech. Drag it along the recording to try another passage. 3. **Amount**: lower keeps more of the original sound, higher cleans more. 4. **Listen to** Cleaned or Original, to compare (⇧ ⌘ O). 5. **Apply** cleans the whole recording at that Amount. Outside the sheet, **Cut › Listen to Original** (⇧ ⌘ O) flips the main preview between the cleaned and the original sound. A rendered video uses the cleaned voice when cleanup is on. An export to DaVinci Resolve always uses the original recording, so you can do your own sound work there. ## Related - [Edit View and Graphics](https://sashimii.app/docs/edit-view-and-graphics/) - [Exporting](https://sashimii.app/docs/exporting/)
