Cut Audio Online - Free
Remove a section from the middle of your audio and join what remains. Cutting is the opposite of trimming - you select the part you want gone, not the part you want to keep. The remaining audio is stitched together at the sample level.

Problems This Tool Solves
There is a click or pop where my audio was joined
The waveform was not at zero at the cut point. Apply a 50–100 ms fade at the edit point to smooth it.
I need to remove multiple sections but each cut shifts my timestamps
Work from the end of the file backward. Later cuts do not shift earlier positions.
The background noise changes at the cut point
Different sections have different ambient sound. Use Noise Removal on the full file before cutting, or add a short crossfade at the join.
Common Use Cases
Delete a mistake from a recording
Remove a cough, stutter, or wrong take from a voice memo or narration without starting over.
Remove ads from a podcast
Select the ad break, cut it out, and the episode plays straight through.
Cut dead air or long pauses
Tighten a recording by removing stretches of silence that slow the pace.
Shorten a song for an event
Remove a verse or bridge to fit a song into a shorter time slot.
How to Cut Audio Online
- Upload your audio file by dropping it into the editor or tapping Upload.
- Select the section you want to remove by dragging on the waveform. Use the time inputs for precision.
- Click Delete Selection. The unwanted part is removed and the remaining audio joins together.
- Preview the result to make sure the join sounds clean. Apply a short fade at the edit point if needed, then export.
Cut vs Trim - Which One Removes What?
Cut (Delete Selection)
Removes the selected section. Everything outside the selection stays and gets joined into one file.
Best for: removing mistakes, ads, silence, or any unwanted middle sectionTrim (Keep Selection)
Keeps only the selected section. Everything outside is discarded.
Best for: isolating a clip, making a ringtone, extracting a highlightEditing Workflow for Cutting
- Remove Noise - Clean background noise before cutting so joins sound seamless
- Cut - Remove unwanted sections from the recording
- Fade - Apply micro-fades at cut points to eliminate clicks
- Normalize - Bring the final result to a consistent level
Quick Tips
- Cut during natural pauses between words for the smoothest join.
- Apply a 50–100 ms fade at the edit point to prevent clicks where the audio joins.
- If you need to remove multiple sections, work from the end of the file backward so your timestamps stay accurate.
- Preview the result before exporting. If the join sounds abrupt, undo and adjust your selection edges.
- Watch for background noise level changes at the cut point. Different sections may have different ambient sound.
- When cutting interviews recorded in different rooms, the ambient tone changes at the join. Run Noise Removal on the full file before cutting to minimize the contrast.
Common Misconceptions
Myth: Cutting audio always creates a click
Reality: Clicks happen when the cut lands at a non-zero sample. Cutting at natural pauses or applying a 50 ms fade eliminates them completely.
Myth: Cut and trim are the same thing
Reality: They are opposites. Trim keeps your selection. Cut removes your selection and joins what remains.
Common Problems and Fixes
There is a click or pop at the cut point
The waveform was not at zero at the join. Select a short region around the edit point (a few milliseconds on each side) and apply Fade In or Fade Out to smooth the transition.
The remaining audio sounds jumpy or unnatural
You may have cut mid-word or mid-phrase. Undo, adjust your selection to start and end at natural pauses, and cut again.
I accidentally removed the wrong section
Use Undo (up to 6 steps) to restore the removed audio. Then adjust your selection and try again.

Frequently Asked Questions
Can I cut multiple sections from one file?
Yes. Select a section, delete it, then select the next section and delete again. Each operation is a separate undo step so you can reverse any individual cut.
Will cutting create a click at the edit point?
It can, if the waveform is not at zero at the join. Apply a short fade (50–100 ms) around the edit point to smooth it. Cutting at natural pauses helps avoid this.
What is the difference between Cut and Split?
Cut removes a section and joins the remaining audio into one file. Split divides the file into multiple separate files at the points you mark. Split gives you several output files, Cut gives you one.
Can I preview the result before exporting?
Yes. After cutting, press Play to hear how the joined audio sounds. If it needs adjustment, Undo and try different selection boundaries.
How do I remove multiple sections from one file?
Select the first section and delete it, then select the next and delete again. Work from the end of the file backward so your timestamps stay accurate - earlier cuts shift all the audio after them.
The audio sounds jarring at the cut point even though there is no click
Different sections may have different background noise levels. The jump in ambient sound is noticeable even without a click. Apply a short crossfade at the join, or run Noise Removal on the full file before cutting.
Can I remove multiple ad breaks from a podcast in one pass?
Yes. Select the first ad section, delete it, then select and delete the next. Each cut is a separate undo step. Work from the end of the file backward so earlier timestamps stay accurate after each removal.
