Free Audio Cutter – Remove Sections Precisely with Audacity

What Is the Cut Command?

Cut removes the selected audio from your track and places it on the Audacity clipboard. The audio to the right of the selection automatically shifts left to fill the gap, leaving a continuous waveform with no silence in place of the removed section. Use Cut to delete mistakes, remove dead air, trim intros, or rearrange parts of a song by pasting the cut audio into a new location.

How to Cut Audio in Audacity

Step 1: Select the Audio to Remove

Click and drag across the waveform to highlight the section you want to remove. For a more precise selection, zoom in with Ctrl+1 / Cmd+1 or type exact times into the Selection Toolbar at the bottom of the window.

Step 2: Apply the Cut Command

Press Ctrl+X (Windows/Linux) or Cmd+X (Mac). You can also go to Edit → Cut from the menu bar or right-click the selection and choose Cut. The command takes effect immediately with no dialog box.

Step 3: Verify the Remaining Audio Shifts Left

After cutting, the audio to the right of the removed section shifts left to close the gap. Your total track length shortens by exactly the length of the cut. Play back from around the edit point to confirm the transition sounds clean.

Step 4: Paste Elsewhere or Discard

The cut audio sits on Audacity's internal clipboard. Paste it into the same track, a different track, or even a different Audacity project window with Ctrl+V / Cmd+V. If you don't need the audio, simply leave it — it will be discarded the next time you cut or copy something.

Cut Command Behavior Explained

Keyboard Shortcut (Ctrl+X / Cmd+X)

The fastest way to cut. Press Ctrl+X on Windows and Linux, or Cmd+X on Mac. You can also access Cut via the Edit menu or right-click context menu. Cut has no dialog box — it acts immediately on whatever is currently selected.

Audacity Clipboard

Cut audio is stored on Audacity's internal clipboard, separate from your system clipboard. It stays there until you cut or copy again, so you can paste the same selection multiple times with Ctrl+V / Cmd+V.

Ripple Edit (Auto-Shift)

By default, Cut performs a ripple edit: audio to the right of the selection shifts left to close the gap. Your total track length shrinks by exactly the length of the cut selection.

Cut and Leave Gap

If you need to remove audio without shifting the remaining content, use Edit → Remove Special → Split Cut instead. This places the audio on the clipboard but leaves silence behind, preserving the original timing of everything after the cut.

Cut Lines (Optional)

Enable cut lines in Preferences → Tracks Behaviors to show a vertical marker where each cut was made. Cut lines let you restore removed audio later by dragging the line, which is useful for non-destructive editing workflows.

Cut vs Delete vs Trim vs Split

Common Use Cases

• Edit podcasts — Remove ums, coughs, and long pauses from spoken recordings
• Trim dead air — Cut silence at the start or end of a recording
• Remove voiceover mistakes — Delete flubs and retakes without exporting again
• Rearrange song sections — Cut a chorus and paste it elsewhere in the track
• Create ringtones — Cut everything outside your chosen 30-second segment
• Remove unwanted audio — Cut out background noise, clicks, or interruptions
• Tighten interviews — Cut tangents to keep the conversation on track
• Clean up music — Remove accidental string squeaks or amp buzz between phrases

Tips for Best Results

• Zoom in with Ctrl+1 / Cmd+1 before cutting to select boundaries at sample-level precision
• Use Preferences → Tracks Behaviors to enable cut lines for non-destructive editing
• Cut at zero-crossings (View → Zero-Crossings) to avoid clicks and pops at the edit point
• Press Ctrl+Z / Cmd+Z immediately to undo if you cut the wrong section
• Use Split Cut (Ctrl+Alt+X) instead of Cut when you need to keep the timing of later audio intact
• Apply a short fade-in or fade-out at the cut edges to smooth abrupt transitions

Frequently Asked Questions

What is the keyboard shortcut for Cut in Audacity?
Press Ctrl+X on Windows and Linux, or Cmd+X on Mac. You can also use Edit → Cut from the menu bar, or right-click the selection and choose Cut.

What is the difference between Cut and Delete in Audacity?
Both remove the selected audio and shift the remaining audio left, but Cut places the removed audio on Audacity's clipboard so you can paste it elsewhere. Delete discards the audio entirely without copying it.

How is Cut different from Trim?
Cut removes the selected portion and keeps everything else. Trim does the opposite — it keeps only the selected portion and removes everything outside it. Use Cut to remove mistakes; use Trim to isolate a single clip.

Why does the rest of my audio shift after I cut?
Cut performs a ripple edit by default, so audio after the selection slides left to close the gap. If you want to keep timing intact and leave silence in place of the cut, use Edit → Remove Special → Split Cut instead.

Can I paste audio I cut into another track or another Audacity project?
Yes. After cutting, click the insertion point on any track (even in a different Audacity project window) and press Ctrl+V / Cmd+V to paste. The audio stays on Audacity's clipboard until you cut or copy something else.

How do I cut out part of a song without clicks at the edit point?
Enable View → Zero-Crossings (or press Z) before cutting. Audacity will snap your selection to the nearest zero-crossings, which removes the click or pop that often occurs at abrupt waveform edges.

Can I undo a cut in Audacity?
Yes. Press Ctrl+Z / Cmd+Z immediately after cutting to restore the removed audio. Audacity supports unlimited undo throughout the editing session.

How do I cut audio precisely at the exact millisecond?
Zoom in with Ctrl+1 / Cmd+1 until you can see individual samples, then drag your selection. You can also type exact start and end times into the Selection toolbar at the bottom of the window for sample-accurate cuts.
