Cue Sheet Generator
Turn the markers you placed on the waveform into a CUE sheet or a Podcasting 2.0 chapters file, so any player can show your track or chapter list.
How to make a cue sheet
- 01
Open the audio file
Load the MP3, M4A or WAV the cue sheet describes. Nothing is uploaded.
- 02
Place a marker pair per track
Every start/end pair becomes one track in the cue sheet, in the order you placed them.
- 03
Export the cue sheet
Download the .cue file, the chapters file, or both together with the audio clips.
What a cue sheet actually does
A cue sheet is a small text file that tells a player where each track or chapter starts inside one audio file. With a cue sheet, a single 700 MB file behaves like an album: the player shows track names, you can jump between them, and a CD-burning tool can split it back into separate tracks. The format has been stable since the CD era, which is why it still works everywhere.
CUE sheet vs Podcasting 2.0 chapters
A .cue file is the right format for an album, a DJ set or an audiobook that a media player will open. A Podcasting 2.0 chapters file (a JSON document) is the right format for a podcast episode, because podcast apps read it and render a chapter list with titles and links inside the player. The same marker pairs produce both - you only have to choose which one to download.
Why markers beat hand-written timestamps
Writing a cue sheet by hand means listening to the file and typing timestamps, then re-typing them every time a boundary moves. Here the markers are the source of truth: place them on the waveform where you can hear the boundary, then export the file. If you nudge a marker, the cue sheet moves with it.
Timestamps you can trust
The generator writes the frame-accurate time of every marker, the duration of each segment and the file names of the exported clips, so the cue sheet and the audio it describes cannot drift apart.

Questions
- What is a CUE sheet used for?
- It tells a player where each track or chapter starts inside one audio file, so the file behaves like an album or an audiobook.
- Which players read chapters files?
- Podcast apps that support the Podcasting 2.0 chapters format, plus most audiobook players and media players that read CUE sheets.
- Is the export free?
- Generating the file is part of Pro; splitting the audio itself stays free, unlimited and lossless.
- Can I import a cue sheet instead of making one?
- Not yet - the generator only writes cue sheets and chapters files from the markers you place. If your file ships with a cue sheet, read the timestamps off it and place the markers on the waveform at those points.
- Do I need to upload the audio file?
- No. The cue sheet is generated from the markers in your browser; the audio never leaves your device.
- What does the generated file contain?
- One entry per marker pair, with the start time, the duration and the exported file name of each segment.
