One MP3 In, Many Tracks Out
You have one long MP3 file — a rehearsal recording, a lecture, a podcast episode, or a live set. You need it split into individual tracks. AudioMultiCut does exactly this, directly in your browser.
Unlike tools that make you trim one section at a time, AudioMultiCut lets you mark all the tracks you want in a single session, then export them all at once.
Example: 8 songs from one MP3
Each colored section becomes its own MP3 file.
How to Split an MP3 Into Tracks
Upload Your MP3
Drag your MP3 file into AudioMultiCut or click to browse. The waveform appears immediately so you can see the structure of your recording.
Mark Your Tracks
Click and drag on the waveform to select each track. For long files (8+ minutes), use auto-detection to find tracks automatically based on silence gaps.
Tracks marked on the waveform:
Fine-Tune Each Track
Play back each segment to check the start and end points. Drag the boundaries to adjust. Each track has its own mini-waveform and playback controls.
Download Your Tracks
Export each track as MP3 or WAV. Use batch download to get all tracks at once. MP3 encoding runs at 20x speed — a 60-second track exports in about 3 seconds.
Common Reasons to Split MP3 Files
Music & Rehearsals
Split a rehearsal recording into individual songs. Share specific songs with band members instead of one huge file.
Lectures & Courses
Break a long lecture into chapter-sized tracks. Students can jump to the topic they need to review.
Podcasts & Interviews
Extract individual segments or highlights from a long podcast recording. Create clips for social media.
Frequently Asked Questions
Can I keep the output as MP3?
Yes. AudioMultiCut exports each track as an MP3 file by default. You can also choose WAV for lossless quality if needed.
How many tracks can I create from one MP3?
There is no limit. Create as many tracks as you need. Users commonly split files into 5-15 tracks, but you can create more.
Does it work with other formats too?
Yes. While this page focuses on MP3, AudioMultiCut supports M4A, WAV, OGG, FLAC, AAC, OPUS, WEBM, and more. All formats can be split the same way.
Is my MP3 file uploaded anywhere?
No. Everything happens in your browser. Your MP3 file never leaves your device. AudioMultiCut uses the Web Audio API for local processing.
What is the maximum MP3 file size?
There is no hard limit. File size depends on your browser and available memory. Most modern browsers handle MP3 files over 500MB without issues.
Can I rename each track before downloading?
Each segment in AudioMultiCut has its own card where you can name it. The filename is used when you download the track.
