How to use this workflow
Load the recording and split
Choose a supported local file. Use waveform zoom to find an edit point and split the recording into segments.
Delete or reorder the segments
Remove unwanted parts and change the order of the remaining segments. Undo and redo let you revise the edit; the history retains up to 100 entries.
Listen to the joins and generate
Adjust the crossfade and preview transitions. Generate the edited output and download WAV. Use the converter separately when you need an MP3 copy.
An example edit you can reproduce
Suppose a recording contains an introduction, a first take and a second take. Split at their boundaries, delete the first take and leave the introduction followed by the second take. This describes an editing workflow; no demonstration recording is included.
Preview both sides of every join. A technically valid cut can still interrupt a word, breath or musical phrase. Choose boundaries by listening as well as by looking at the waveform.
Beat snapping and crossfades
When tempo analysis produces a usable result, beat snapping can help align edit points to the estimated grid. It is guidance, not a guarantee that every transient in a changing-tempo performance will line up.
The cutter applies equal-power crossfades around joins while preserving the edited timeline’s duration. A fade can soften clicks but cannot make two unrelated phrases musically compatible. This is a segment editor for one source, not a multitrack recorder or a full DAW.
Common questions
Can I cut an MP3 file?
If the browser decodes the MP3, you can edit it here. The direct edited download is WAV; convert that WAV to MP3 afterward if required.
Which tool should I use just to remove silence at the ends?
Use the audio trimmer for a single start-to-end selection. The cutter is useful when you need multiple segments or a different order.
