How to split an audio file online
Audio Splitter divides one audio file into smaller parts directly in your browser. It is useful for long voice notes, interviews, podcasts, audiobook chapters, language lessons, and datasets that need shorter clips.
- Select or drag an MP3, WAV, M4A, OGG, FLAC, or AAC file into the upload area.
- Wait for the waveform to appear. The file is decoded locally on your device.
- Choose whether to split by number of parts or by maximum duration.
- Select the output format and start the split process.
- Download the generated parts as a ZIP file and save them to your device.
Audio Splitter FAQ
Are my audio files uploaded?
No. The selected file is read and processed in your browser. AudioCutter does not upload your audio content to a server.
What split methods are available?
You can split by a fixed number of parts or by a maximum duration per part. The tool calculates the resulting boundaries before processing.
Which output formats can I use?
MP3 and WAV are the safest options across browsers. FLAC, AAC, OGG, and M4A depend on browser support and the available encoder path.
Why does a large file take longer?
Large files require more memory and encoding time because all processing happens on your own device instead of a remote server.
