Split Audio
Free online audio splitter with waveform view. Click to split, auto-detect and remove silent parts, then export selected segments as WAV or MP3 in a ZIP — all in your browser.
About this tool
Split long recordings into segments right in your browser. Click the waveform to add split points, or run automatic silence detection to separate speech from blank parts — silent segments are marked as excluded by default, so you export only what you need. Each kept segment is exported as WAV or MP3 and packed into a single ZIP file.
How to use
- Click or drag to select an audio file
- Click the waveform to add split points, or use "Detect silences" to split automatically
- Uncheck segments you want to drop (detected silences are excluded by default)
- Choose WAV or MP3 and export all kept segments as a ZIP
FAQ
How does silence detection work?
The tool scans the waveform for regions where the volume stays below the threshold for at least the minimum duration you set. Those regions become excluded segments, and everything else becomes a kept segment.
Can I adjust the automatic result?
Yes. Every segment can be re-included or excluded with its checkbox, you can click the waveform to split further, and "Merge next" joins a segment with the following one.
What do I get after exporting?
A ZIP file containing one audio file per kept segment, numbered in order (e.g. recording_01.wav, recording_02.wav). Excluded segments are skipped entirely.
Are my audio files uploaded to a server?
No. Decoding, splitting and encoding all run locally in your browser. Your files never leave your device.
