How to Split Audio Files Online
Splitting a long audio recording into individual segments is one of the most common audio editing tasks — and it used to mean downloading software just to do it. AudioMultiCut makes it possible entirely in your web browser, with no installation required.
What is audio splitting?
Audio splitting means taking one continuous recording and dividing it into multiple shorter clips. For example, a two-hour band rehearsal might contain eight different songs; splitting it produces eight individual MP3 files, one per song. The same principle applies to lectures, meeting recordings, podcast recordings, live shows, language lessons, AI-generated voiceovers, and any other multi-segment audio.
The four-step process
- 1
Upload your audio file
Drag and drop your MP3, WAV, M4A, or other audio file onto the upload zone, or click to browse your files. The file is loaded directly into your browser. Nothing is sent to a server.
- 2
View the waveform and detect segments
Once uploaded, the full waveform renders in your browser. For recordings 8 minutes or longer, use Auto-Cut to detect silent gaps between segments. For speech files on supported devices, optional local browser-based Whisper word detection can show words and approximate word timings.
- 3
Review and fine-tune your segments
Click and drag on the waveform to manually create a segment, or adjust the start and end points of any auto-detected segment. Every time you trim a segment edge, AudioMultiCut plays that edge right away so you can hear exactly what changed.
- 4
Download individually or all at once
Download each segment as an MP3 or WAV file, or use batch export to download all segments one after another. Files are named sequentially and are ready to use immediately.
Hear the Trim Right Away
Trim a segment's start or end and AudioMultiCut plays that edge right away, so you can hear what changed without replaying the whole clip.
Who uses audio splitting?
Musicians and bands record full rehearsals and need individual tracks per song for review, archiving, or sharing with bandmates. Teams and consultants record standups, client calls, discovery meetings, trainings, and user interviews, then split them into decisions, requirements, and follow-up clips. Teachers and educators record hour-long lectures and split them into topic-based clips for students to study. Podcasters and journalists record long interviews and extract the best moments as standalone clips. Voiceover creators bring generated speech from ElevenLabs, Speechify, Murf, PlayAI, LOVO, WellSaid, and other voice-generator tools, then cut it into sentences, script lines, pickups, and alternate takes.
For spoken-word files, AudioMultiCut can also offer local browser-based Whisper word detection when the browser and device are strong enough. It runs a small AI model in the browser, so it may miss words or be unavailable on some devices, operating systems, and browser versions, but when it works it makes it much easier to cut by what is being said.
Because AudioMultiCut runs entirely in your browser using the Web Audio API, your recordings stay completely private. No audio data ever leaves your device, so interviews, private lessons, and other sensitive recordings never leave your machine.
Choosing the Right Export Format
AudioMultiCut offers MP3 and WAV output, plus an original-quality M4A option for compatible M4A/AAC sources. The right choice depends on how you plan to use the file.
M4A Original: fastest, with no added quality loss
When the source is compatible M4A or AAC audio, Original-quality M4A copies the compressed audio frames into each clip without encoding them again. It is fast, keeps the source quality and bitrate, and aligns cut points to the source audio frames.
MP3: smaller, shareable files
MP3 is a lossy audio format that uses psychoacoustic compression to reduce file size significantly, typically 5–10× smaller than an equivalent WAV file. A three-minute segment encoded at 128 kbps MP3 will be roughly 2.8 MB, compared to 30 MB for WAV. MP3 files play on virtually every device, streaming platform, and media player.
Best for: sharing files by email or messaging apps, uploading to SoundCloud or YouTube, sending to bandmates for casual listening, or any situation where portability matters more than technical perfection.
WAV: full quality, no compression
WAV files store uncompressed audio data, preserving every detail of the original recording. There is no quality loss from encoding, which is why it's the go-to when you still need to edit the file.
Best for: archiving original recordings, importing into GarageBand, Logic Pro, Audacity, or other DAWs, professional mastering workflows, and any case where you need to preserve maximum audio fidelity.
| Feature | MP3 | WAV |
|---|---|---|
| File size (3 min) | ~2–4 MB | ~30 MB |
| Audio quality | Good (lossy) | Perfect (lossless) |
| Universal playback | ✓ Yes | ✓ Yes |
| DAW/editing import | ~ Acceptable | ✓ Preferred |
| Easy to share | ✓ Best | ~ Large files |
Note on M4A source files: Choose M4A Original quality to avoid re-encoding a compatible M4A/AAC source. Choosing MP3 still performs a lossy conversion; choosing WAV produces uncompressed audio.
Frequently Asked Questions
Is AudioMultiCut free to use?▾
Yes. The web tool is free, has no ads, has no registration requirement, and does not add watermarks to exported files. If you prefer a native phone experience with saved projects, the iOS app is free for recordings up to 10 minutes and offers AudioMultiCut Unlimited for longer recordings.
What audio formats does it support?▾
AudioMultiCut accepts MP3, WAV, M4A (AAC), OGG, FLAC, and most other audio formats supported by your browser. Export options include MP3, WAV, and original-quality M4A stream copy for compatible M4A/AAC sources, plus browser-dependent Opus formats.
Can I split ElevenLabs or other AI-generated voice files?▾
Yes. Download the audio from ElevenLabs, Speechify, Murf, PlayAI, LOVO, WellSaid, or another voice-generator tool, then open it in AudioMultiCut. You can split the generated speech into sentences, lines, pickups, alternate takes, or production clips. On supported devices, local Whisper word detection can also show spoken words and approximate word timings.
Can AudioMultiCut detect words or transcribe speech in the browser?▾
On supported computers and browsers, yes. AudioMultiCut can optionally use a local browser-based Whisper AI model to find spoken words and rough word timings without uploading your audio to AudioMultiCut servers. It is cutting-edge browser AI, so it may be slow, unavailable, or inaccurate on some devices, operating systems, browsers, and files.
Does it work on mobile phones and tablets?▾
Yes. The app is fully responsive and works on iOS Safari, Android Chrome, and other mobile browsers. File upload and waveform interaction are touch-friendly. For best experience with large files, a desktop or laptop is recommended.
Is there an Android version of AudioMultiCut?▾
Yes. AudioMultiCut has an Android app for supported Google Play regions, and Android users can also use the free web tool at audiomulticut.com in a modern mobile browser. The web tool processes audio locally on the device.
Is my audio file uploaded to a server?▾
No. All audio processing happens locally in your browser using the Web Audio API. Your file never leaves your device and is never sent to any server. This makes AudioMultiCut suitable for confidential recordings.
How much does the iOS app cost?▾
As of July 2026, recordings up to 10 minutes are free in the iOS app with editing and export. AudioMultiCut Unlimited removes the length limit for longer recordings through an auto-renewing monthly App Store subscription. Prices may vary by region and are shown by Apple before purchase.
How does automatic segment detection work?▾
The auto-detection algorithm analyzes the audio's RMS energy level over time and identifies stretches of silence where the volume drops below a configurable threshold for a minimum duration. Each gap between silences is marked as a segment in one pass. You can adjust the silence threshold and minimum gap length in the settings.
Can I manually adjust segment start and end points?▾
Yes. After creating a segment (either manually or via auto-detection), you can fine-tune its start and end times using the precision sliders on each segment card. You can also click and drag directly on the waveform to create new segments. As you trim either edge, AudioMultiCut automatically previews the first or last second so you can hear the new boundary immediately.
What is the maximum file size?▾
There is no hard file-size limit enforced by the app — the real limit is your device's available RAM. AudioMultiCut warns you when a recording is longer than 3 hours because decoding can take longer and use much more memory. Files over 3 hours 30 minutes are supported only on desktop browsers, and 4 hours 30 minutes is the maximum.
How do I download all segments at once?▾
After creating your segments, click the "Download All" button in the segments panel. AudioMultiCut prepares each segment and downloads the files one after another. If your browser asks for permission to allow multiple downloads, approve it for AudioMultiCut. Individual segments can also be downloaded one at a time from their own cards.
What's the difference between the website and the iOS app?▾
The website is the free browser splitter: it is useful when you want no-install audio cutting, local browser processing, and MP3, WAV, or compatible original-quality M4A exports. The iOS app adds a native phone workflow with saved projects, import from iPhone apps, merge, video-to-audio extraction, export defaults, and easier sharing through Messages, WhatsApp, Telegram, AirDrop, Files, and other iOS destinations.
Can AudioMultiCut extract audio from a video?▾
Yes. The iOS app can import video files and extract the audio track so you can split, trim, merge, and export it like any other recording. The website also includes separate browser tools for working with local video files.
