One file, many songs: a digitized cassette, a live set, a vinyl rip, a two-hour rehearsal recording. Splitting it into tracks used to mean installing an editor and learning its timeline. In a modern browser, it's ten minutes of clicking on a waveform.
The workflow
- Drop the file on the audio splitter. It decodes locally (MP3, WAV, M4A, and OGG all work) and draws the full waveform.
- Read the waveform before you click. Track boundaries are visible: songs are dense blocks, gaps are flat lines. A two-hour set at a glance is exactly why waveform editing beats scrubbing by ear.
- Click the wave to drop a cut marker at each boundary. Markers are dashed orange lines; every region between markers becomes one track.
- Audit with playback. Each track row has a Play button that starts exactly at its cut — the fastest way to confirm you're not clipping an intro.
- Export. One track saves as a WAV file; multiple tracks arrive as a numbered ZIP (
track01,track02, …).
Let silence do the work
For recordings with real gaps between songs — tape rips, rehearsal takes, lecture recordings with breaks — press Cut at silences. The splitter scans the audio for stretches where the level stays near zero and drops a marker in the middle of each gap.
Silence detection is honest about its limits: it finds silence, not musical boundaries. It works beautifully on album rips and spoken recordings with pauses, and poorly on continuous DJ mixes (no gaps to find) or vinyl with heavy surface noise (no true silence). For those, place markers by eye — the waveform's shape still shows you the transitions.
Placement details that matter
- Cut in the gap, not at the first note. A track that starts a half-second before the music breathes; a track that starts mid-attack sounds clipped. Aim markers at the center of the flat region.
- Fades belong to the earlier track. When song A fades out, put the cut after the fade completes, not where the fade begins.
- Wrong marker? Clear cuts and re-place, or just add a marker in the right spot and ignore tiny stub segments under a twentieth of a second — the splitter drops them automatically.
About the output format
Tracks export as 16-bit WAV at the source sample rate — uncompressed and lossless from the decoded audio, ready for any player, DAW, or a later encode to MP3/AAC at your choice of bitrate. Why WAV and not MP3 directly? Encoding to MP3 in the export would lock in generation loss; WAV keeps your options open. The trade-offs are covered in WAV vs MP3 for exports.
Everything — decode, waveform, cuts, export — happens on your device. A bootleg-quality live recording or an unreleased demo never leaves your browser tab.
