What is the Audio Cutter?
The Audio Cutter lets you cut a song into pieces anywhere — not just at the start and end. Split the track at any point, delete the sections you don't want, move pieces into a new order, and the remaining pieces close up seamlessly with an automatic crossfade at every join.
Unlike desktop editors, there is nothing to install, and unlike most online tools, your file is never uploaded. All cutting, crossfading, and beat detection runs locally in your browser — your audio never leaves your device.
How to Cut a Song
1. Drop in your audio file
Upload an MP3, WAV, FLAC, or any common audio format. The waveform appears instantly and beats are detected automatically for snapping.
2. Split at the cut points
Tap the waveform to place the playhead — it snaps to the nearest beat — then press Split. Zoom in for razor-sharp precision on exactly the right moment.
3. Delete or reorder pieces
Select a piece to delete it, or move it earlier and later in the timeline. The other pieces close up automatically — no gaps, no overlaps, and every join gets a smooth crossfade.
4. Preview and download
Press Play to hear exactly what you'll get — the preview is identical to the export. Download as WAV or MP3 when it sounds right.
Why the Cuts Sound Smooth
Automatic crossfades
A raw cut between two pieces of audio usually makes an audible click or pop. The Audio Cutter blends every join with an equal-power crossfade — borrowing a few milliseconds of audio from just outside each cut, the way professional editors do — so the pieces flow into each other and the song's length and timing stay exactly on the grid.
Snap to the beat
The tool detects your song's tempo and shows beat lines on the waveform. With snapping on, every cut lands exactly on a beat, so a shortened song still grooves — verses connect to choruses like the arrangement was always that way.
What Can You Do With It?
Shorten a song
Cut a repeated chorus or a long bridge out of a track and let the rest flow together — perfect for versions that need to fit a time limit.
Dance & performance edits
Build competition and recital mixes: cut the intro, tighten the middle, and end exactly on the big hit, with every cut on the beat.
Podcast & voice cleanup
Remove a flubbed take, a long pause, or an off-topic tangent from the middle of a recording, and the surrounding audio joins up smoothly.
Rearrange sections
Move the drop earlier, repeat-free: reorder a song's sections into a new arrangement without any other software.
Frequently Asked Questions
Is this audio cutter really free?
Yes — completely free, no account, no watermarks, no limits on the number of cuts. It's supported by a small sponsor banner.
Does my audio get uploaded to a server?
No. Everything — decoding, cutting, crossfading, beat detection, and export — runs locally in your browser. Your file never leaves your device, which also makes it fast: there's no upload or download wait.
How is this different from the Audio Trimmer?
The Trimmer cuts from the start and end of a file — simple and quick. The Audio Cutter edits the middle: split anywhere, delete sections, reorder pieces, and every join gets an automatic crossfade. Use the Trimmer for topping and tailing; use the Cutter to restructure a song.
Why don't my cuts click or pop?
Every join is blended with a short equal-power crossfade, borrowing a few milliseconds of audio from outside each cut — the same technique professional audio editors use. You can pick the crossfade length, from a barely-there 10 ms to a long 200 ms blend.
What does beat snapping do?
The tool analyzes your song's tempo and draws beat lines on the waveform. When snapping is on, the playhead and your cuts land exactly on those lines, so edits stay in time and a shortened song still sounds natural. You can turn it off for free-position cuts.
What audio formats can I cut?
MP3, WAV, FLAC, M4A/AAC, and OGG files up to 250 MB. You can download the result as WAV (lossless) or MP3.
