Audio Splitter
Open one recording and divide it at the times you enter, into equal parts or at a fixed interval. The waveform marks each part; download individual WAV files or the whole set as a ZIP. Audio stays in this browser tab. Files can be up to 50 MB and 30 minutes, with up to 100 parts.

Ready. Choose an audio file, or drop one on the stage.
Times takes the points to cut at, so 3:00, 7:00 on a ten minute file gives three parts. Equal parts divides the file into as many pieces as you ask for, and Every cuts at a fixed length and keeps the short final piece rather than dropping it. Every part is a button: click one to select it, then download that part on its own, or take the whole set as a ZIP. A split makes at most 100 parts, and the file ceilings are 50 MB and 30 minutes, because the whole recording is decoded to 32-bit samples in the memory of this tab before anything is cut.
Common questions
- What is an audio splitter?
- A file splitter divides one recording into shorter audio files. This page cuts at typed times, into equal parts or at regular intervals. A headphone, microphone, HDMI, optical or other cable splitter divides physical signals between connectors; this page does not replace that hardware.
- How do I split an audio file into tracks or equal parts?
- Open audio, then choose Times and type cut points such as 3:00, 7:00; choose Equal parts and enter a count; or choose Every and enter an interval. Every keeps a shorter final piece. Select a part and use Download part, or choose All as ZIP for every WAV. This cuts a recording in time; it does not separate voices, instruments or stereo channels.
- Can I split MP3 and WAV audio online?
- WAV input and MP3 input can be decoded when supported by your browser. Every downloaded part is a 16-bit PCM WAV, including parts cut from an MP3; there is no MP3 export. Other formats depend on the browser decoder. If a file cannot be decoded, export it to WAV first.
- Can I split a recording on a PC, iPhone or iPad?
- Use a current browser with a file chooser, Web Audio decoding and file-download support on your PC, iPhone or iPad. Open the recording, choose the cuts, then save the WAV parts or ZIP through the browser. Input format support and download destinations depend on the browser, and the same 50 MB, 30-minute and 100-part limits apply. This is recording-file editing; it does not route device sound to headphones or replace an audio cable splitter.
- Is my recording uploaded or remembered?
- The file is decoded and cut in this browser tab, without an upload or an account. Only the mode, cut times, part count and interval are remembered in this browser; the audio is not. Start over clears those saved settings.
- How exact are the cut points?
- Times round to the nearest decoded sample. For example, 3 seconds at 44.1 kHz is sample 132,300; 7 seconds is sample 308,700. Each segment starts where the previous one ends, with no dropped or duplicated samples between cuts. WAV export rounds the decoded floating-point samples to 16-bit PCM and clamps values past full scale.
- Is there silence detection or AI stem separation?
- There is no silence detection here: the tool does not detect silence, find pauses or move your cut points automatically. Use the waveform to choose times yourself. It also has no AI model for separating vocals, drums or other instrument stems.
- What are the file, length and part limits?
- The current limits are 50 MB of file, 30 minutes of decoded audio and 100 parts. The file size is checked before reading and duration after decoding. The recording and WAV outputs use memory in this tab. Settings that would exceed the limits receive a message saying what to change.
- What if a cut time is invalid?
- Cuts at zero, at or past the end, repeated on the same sample or not written as a time are refused. Accepted forms include 3:00, 1:02:30 and 45 for forty-five seconds. A valid list entered out of order is sorted before planning the parts.
- Can I download all the parts at once?
- All as ZIP writes each WAV and puts them in one ZIP download, with progress shown. Stop cancels that export. Parts have numbered filenames so they sort in order. A selected part can also be downloaded on its own.
Cuts land on the nearest sample to the time you enter. Before export, contiguous segments rejoin the decoded recording sample for sample; each part is then written as uncompressed PCM WAV with 16-bit rounding and full-scale clipping. It does not find the gaps for you: there is no silence detection here, so the cut points are the ones you set.
