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.
Speed control built in
Slow down or speed up the selected clip from 0.5x to 2x before exporting the result.
Downloadable WAV output
Export a clean WAV file that can be reused in video editors, podcasts, dubbing tools, and LipsyncX Studio.
Local browser processing
The edit runs in the browser with Web Audio, so quick cuts do not need a server-side render job.
