Frequently Asked Questions
What is a CUE sheet?
A CUE sheet (`.cue` file) is a metadata file that contains track information for audio CDs or large audio files. It specifies track boundaries, titles, artists, and timestamps, allowing a single large audio file to be split into individual tracks.
How do I split MP3 files with CUE sheets?
Simply upload both your MP3 file and its corresponding CUE sheet using the tool above. The splitter will automatically parse the CUE file to identify track boundaries and metadata, then split the MP3 into individual tracks. You can download tracks individually or download all at once.
How can I generate a CUE file?
If you don't have a CUE file, you can create one by providing track timestamps and metadata to AI tools like ChatGPT. Simply tell ChatGPT the track names, artists, and timestamps (e.g., "Track 1 starts at 0:00, Track 2 at 3:45"), and ask it to generate a CUE file. You can then copy the generated content and save it as a .cue file to use with this splitter tool.
Will audio quality be preserved?
The tool decodes the original MP3 and re-encodes each track segment. While MP3 is a lossy format, the tool uses the browser's MediaRecorder API to encode tracks with high quality settings. The bitrate is automatically selected to preserve the best possible quality from the source.
What metadata is included in split tracks?
Each split track automatically includes ID3v2 metadata from the CUE sheet: track title, artist, album name, track number, total tracks, year, and cover art (if present in the original MP3). This information is embedded using industry-standard ID3 tags for maximum compatibility.
Can I auto-detect paired MP3 and CUE files?
Yes! If you upload a file named "album.mp3", the tool will suggest looking for "album.cue" and vice versa. You can upload files in any order, and the tool will verify they match each other based on the FILE command in the CUE sheet.
Is my data safe and private?
Absolutely. All processing happens entirely in your browser using Web Audio API and MediaRecorder. Your MP3 and CUE files are never uploaded to any server, ensuring complete privacy and security for your music collection.
What output format is used?
Split tracks are exported in MP3 format using the browser's native audio encoding. The encoding automatically preserves quality based on the source audio characteristics, making it ideal for portable music players and streaming.
Can I download all tracks at once?
Yes! After splitting is complete, you can either download tracks individually or use the "Download All Tracks" button to download all tracks sequentially with one click.
What browsers are supported?
This tool works best in modern browsers like Chrome, Edge, Firefox, and Safari. The tool uses Web Audio API and MediaRecorder, which are supported in all modern browsers. For best results, use the latest version of your browser.
