CUE Splitter

How it works

Three Ways to Split an Album or Mix Into Tracks

Drop one long audio file, an album ripped as a single FLAC or WAV, a vinyl side, a recorded DJ set, and define where the tracks change:

• Upload a .cue file. The standard companion to single-file CD rips. Track numbers, titles, artists, and start times load automatically; warnings flag anything unusual in the sheet.
• Paste a tracklist. Any timestamp list works: YouTube chapters, SoundCloud comments, a 1001tracklists entry, or your own notes. Lines like 6:42 Artist - Title are parsed live as you type.
• Set markers manually. Click the waveform to add a split point, drag markers to the exact transition, double-click to remove one. The waveform makes track boundaries easy to spot by eye.

However you define them, the markers and the track table stay in sync: drag a marker and the start time updates, edit a start time and the marker moves. When everything lines up, export every track at once as WAV or MP3 320, or save your split points as a .cue sheet so the work is never lost.

Cue sheets

Where CUE Files Come From

A cue sheet is a small text file that describes how one continuous audio file breaks into tracks: titles, performers, and start times at CD-frame precision. Rippers like EAC and dBpoweramp write one whenever a CD is ripped as a single image instead of separate tracks, which is why so many archived albums arrive as album.flac plus album.cue. Mixed-set recorders and some radio logging tools produce them too. The classic way to split these was 2010-era desktop software like CUETools or Medieval CUE Splitter; this page does the same job in the browser with nothing to install and nothing uploaded.

DJ mixes

How to Split a DJ Mix Without a CUE File

Recorded sets rarely have a cue sheet, but the tracklist usually already exists somewhere: the timestamps you posted with the upload, the ID list on 1001tracklists, the chapter list in a YouTube description. Paste it straight in. The parser is tolerant of numbering, brackets, and dashes, and every line it cannot read is listed as a warning instead of silently dropped. Because DJ transitions are gradual, drag each marker to the spot that sounds right, mid-transition or on the incoming downbeat, then export. If you want fades on the cut points afterwards, run the tracks through the audio fade tool, and tag them properly with the MP3 metadata editor. Building the tracklist itself first? Use the tracklist maker.

Honest limits

Memory Expectations for Long Files

Everything happens locally: the file is decoded once to raw PCM and kept in memory so every split is instant and sample-accurate. That decoded audio is much bigger than the file on disk. A 90-minute stereo mix decodes to roughly 1 to 2 GB of RAM. Modern desktops and laptops handle that without drama; phones and older low-RAM machines may fail on very long recordings, so do multi-hour jobs on a desktop browser. Exports are processed one track at a time precisely so memory use stays flat during a long Split all run. If your segments end with abrupt cuts or dead air, the silence remover cleans up the edges.
