Free Audio Splitter

Split any audio file into multiple parts — equal-length segments, custom timestamps, or auto-detected silence boundaries. Great for splitting audiobooks into chapters, breaking long podcasts into segments, or chopping a live recording into individual songs. Runs entirely in your browser.

SnipSound's Audio Splitter takes one audio file and produces multiple smaller files, with split points placed exactly where you want them. Three modes cover the most common use cases: split into a fixed number of equal parts, place markers manually for chapter-style splits, or let the tool auto-detect silence boundaries between songs. Everything runs in your browser; your files never leave your device.

Three ways to split

Equal parts — split into N segments of equal length. Best when you want a long file chopped up uniformly (e.g. cutting a 4-hour lecture into 8 half-hour chunks to fit transcription upload limits).
Markers — click the waveform to preview from any point with the built-in player, then press Add split here (or the M key) to drop a split point at the playhead. Each marker creates a boundary; the file is cut into markers + 1 parts. Best for chapter-aware splits where you know exactly where each section starts.
At silence — auto-detect quiet stretches longer than your minimum-silence threshold, then place split points at the midpoint of each silence. Best for live recordings, compilation MP3s, and audiobooks where chapters are separated by recognizable pauses.

Common use cases

📚 Split audiobooks into chapters

Use Markers mode at known chapter timestamps, or At silence mode with a stricter minimum (2–3 seconds) for narrator pauses.

🎤 Split a live recording into songs

At silence mode with default settings catches inter-song gaps. Tighten threshold if quiet ambience between songs gets flagged.

🎙 Break a long podcast into segments

Equal parts mode for distribution chunks; Markers mode for chapter-based segmentation.

📝 Beat transcription upload limits

Many transcription services cap a single upload — OpenAI's audio API at 25 MB, for example. Equal-parts splits keep each piece comfortably under the cap.

🎓 Break a lecture into study segments

Splitting an hour-long lecture into 10-minute chunks makes it easier to revisit specific topics without scrubbing.

🎵 Extract individual tracks from a DJ set

If the DJ left transitions audible enough, At silence may catch them. Otherwise drop markers manually at each transition.

Why use SnipSound's splitter

100% in your browser. ChunkAudio, Kapwing, VEED, MiniWebTool all upload your file to a server. We don't — your audio never leaves your device.
Comparing tools? — SnipSound vs ChunkAudio, row by row, with the formats each free tier actually exports.
M4A and iPhone voice memos — a Voice Memo recorded on an iPhone is an .m4a, so it drops straight in and splits like an MP3. A DRM-protected .m4p bought from the iTunes Store cannot be opened by any browser tool, including this one.
Audiobooks — cut a long book into equal parts for a player that loses its place in big files, or use Markers mode to place a split at each chapter start yourself. Embedded chapter marks are not read; you choose the points.
No cap imposed by us. Large files are streamed in pieces rather than loaded into memory, so several gigabytes can go through in one pass.
Three modes in one tool. Most splitters force you to pick between equal-parts and manual markers. We give you both plus silence-boundary auto-detection.
Preview before you commit. Every split point shows up live on the waveform as you tune the controls. No surprise outputs.
Pick any output format. MP3 (320–128 kbps), WAV, FLAC, OGG, AAC, M4A — same encoder pipeline as the rest of SnipSound's tools.

Audio splitter FAQ

How do I split an audio file into multiple parts?▼

Upload your audio file, pick a split mode — Equal parts (specify how many), Markers (preview by clicking the waveform, then press Add split or M to drop a split point at the playhead), or At silence (auto-detect quiet boundaries). The tool previews the split points on the waveform, then click Split to generate downloadable parts.

Can I split an MP3 into individual songs?▼

Yes — if there's a clear silence gap between songs (typical of compilation MP3s and live recordings), use the At silence mode. Tune the threshold and minimum silence sliders until the previewed split lines land between tracks. The default settings work for most recordings with 1–2 second gaps between songs.

How do I split an audiobook into chapters?▼

If you know the chapter timestamps, use Markers mode — click the waveform at each chapter start to add a split point. If chapters end with consistent silence (some audiobook narrators leave longer pauses between chapters), the At silence mode with a stricter minimum-silence value (e.g. 2 seconds) can auto-detect them.

Are the split parts smaller than the original?▼

Yes — each part is encoded independently from the original audio, so file sizes scale with each part's duration. A 60-minute MP3 split into 6 equal parts becomes six ~10-minute MP3s totalling roughly the same size as the input (plus a small per-file MP3 header overhead).

Can I download all parts at once?▼

Yes — after splitting, click Download all parts to trigger sequential downloads of every part. Your browser may ask for permission to download multiple files; click Allow once and the rest follow automatically.

Is my file uploaded to a server?▼

No. All decoding, splitting, and encoding happens in your browser using the Web Audio API. Your audio never leaves your device.

What input formats are supported?▼

Any audio format your browser can decode — MP3, WAV, OGG, FLAC, AAC, M4A. Output formats include MP3 (320, 256, 192, 128 kbps), WAV, FLAC, OGG, AAC, and M4A.
