StudioWavePro’s Audio Splitter takes one audio file and outputs many. Drop in an MP3, WAV, OGG, M4A or FLAC, choose how to split it — at a selection point, into N equal parts, or by a fixed segment length — and each piece downloads as its own WAV file. Useful for breaking up long recordings, slicing a DJ mix back into individual tracks, or cutting a podcast into chapter-sized chunks.

Three modes cover the common use cases. Selection mode cuts at the edges of a region you drag on the waveform — great for isolating a specific moment. Equal-parts mode divides the file into 2–20 evenly-sized segments — perfect for sharing long recordings on platforms with file-size limits. Fixed-duration mode produces parts of an exact length (e.g. every 30 seconds) — ideal for chopping samples or building loops.

When to use

Split a long DJ mix or recorded set into individual tracks.
Break a 2-hour podcast into chapter-sized parts before publishing.
Cut a long voice memo into shareable pieces for WhatsApp or Telegram.
Divide an audiobook chapter into smaller files for easier navigation.
Chop a loop or sample track into evenly-sized slices for beat-making.
Bypass file-size limits on email or chat platforms by splitting long recordings.

How to use

Click "Open Audio Splitter" below to launch the editor.
Drop in any audio file — MP3, WAV, OGG, M4A and FLAC are all supported.
Pick a split mode: at selection edges, equal parts (2–20), or fixed duration.
Adjust the controls — drag a region on the waveform for selection mode, or pick the part count / duration.
Preview the segment list at the bottom of the panel, then click "Split into N files" to download each piece as a separate WAV.

Tips

For DJ sets and live recordings, "selection edges" mode lets you precisely mark track boundaries by ear before splitting.
If you want to split at silent gaps (between songs, sentences, etc.) use the Silence Splitter tool instead — it detects silence automatically.
Equal-parts mode is fastest when you don’t care about exact boundaries (e.g. "give me 4 equal halves of this hour-long file").
Your browser may ask permission to download multiple files the first time you split. Accept the prompt — it’s required to deliver every part.
Filenames include a numbered suffix (`-part01`, `-part02`, etc.) so they sort correctly in any file manager.

Frequently asked questions

How many parts can I split a file into?: Equal-parts mode supports 2 to 20 segments. Fixed-duration mode and selection mode have no hard limit — you’re only constrained by the source file’s length.
Do all the parts download at once?: Yes. The splitter triggers a download for every segment a few milliseconds apart. The first time you split a file, you may need to allow multi-file downloads when prompted.
What audio format are the output parts in?: WAV (lossless). If you need MP3 output for each part, run them individually through the rest of the editor afterward — or convert them with a separate batch tool.
Can I split based on silence automatically?: Yes, but use the Silence Splitter tool for that — it detects silent gaps automatically and splits between them. The Audio Splitter is for manual or time-based splitting.
Is there a file size or length limit?: No hard limit. Very large files (multiple hours) may slow down depending on your computer’s memory. For most podcasts and music files you won’t notice any lag.
Will the audio quality drop?: No. WAV output is bit-perfect — each split point is sample-accurate with zero re-encoding loss.
Will splitting reduce audio quality?: No. The output parts are bit-perfect copies of the original — each cut is sample-accurate with zero re-encoding loss when you export to WAV.
