Audio editing workflow

Upload audio and trim the exact section you need

The workbench combines the two jobs creators usually need: cutting a clean clip and changing its speed before sending it into a video, podcast, subtitle, or lip sync workflow.

Precise trim handles

Move the start and end handles on the waveform, then use time inputs for 0.1 second adjustments.

Speed control built in

Slow down or speed up the selected clip from 0.5x to 2x before exporting the result.

Local browser processing

The edit runs in the browser with Web Audio, so quick cuts do not need a server-side render job.

Downloadable WAV output

Export a clean WAV file that can be reused in video editors, podcasts, dubbing tools, and LipsyncX Studio.

How the audio trimmer works

Upload an audio file, set the start and end handles, adjust speed if needed, preview the selection, and export a WAV file.

Upload Your Audio File

Start with a voice note, song snippet, podcast recording, sound effect, or any common audio format.

2

Trim and Preview the Clip

Select the section to keep with waveform handles, then play the selection before exporting.

Adjust Speed and Download

Audio trimmer use cases for creators

The tool is designed for quick edits that happen before video generation, dubbing, podcast cleanup, or social publishing.

Use the trimmed audio in Studio

Lip sync audio prep

Cut a clean voice clip before uploading it as driving audio for a talking photo or lip sync video.

Podcast clip cleanup

Remove long intros and keep only the section that needs subtitles, highlights, or video repurposing.

Music and sound snippets

Trim a short hook, sound bite, or background audio segment before using it in social content.

Speed matching for video

Adjust pacing when a narration track is slightly too slow or too fast for the visual cut.
