Drag and drop an audio file or click to select it. Supports MP3, WAV, FLAC, OGG, and AAC formats.
Adjust the silence threshold and minimum silence duration to control how the file is split.
Click split and download all audio segments in a single ZIP archive. Each segment is named automatically.
Your audio files never leave your device. All processing happens in your browser — no server uploads.
No registration, no file limits, no watermarks. Split as many audio files as you need, completely free.
Automatically detect silent sections and split audio at the right points. Perfect for podcasts, lectures, and recordings with natural pauses.
Split a continuous podcast recording into individual episode segments at natural pauses — then trim each segment to fine-tune the start and end points.
Separate individual songs from a live concert recording that has silence between performances.
Break up a long lecture recording into shorter chapter segments for easier navigation and sharing.
Split a multi-track audio recording where each take is separated by silence into individual files.
| Format | Description | Best For |
|---|---|---|
| MP3 | Compressed lossy audio | Podcast splitting, music separation |
| WAV | Uncompressed lossless audio | Studio recordings, precise splitting |
| FLAC | Compressed lossless audio | Live concert track separation |
| OGG | Open-source lossy audio | Web audio segmentation |
| AAC | Advanced lossy audio | Mobile recording splitting |
Start with a silence threshold of -30 dB and minimum duration of 1 second, then adjust based on the results.
For podcasts with background music, lower the threshold to -40 dB or below to avoid false splits.
Increase minimum silence duration to 2-3 seconds for lectures to avoid splitting at brief pauses between sentences.
Check the number of detected segments before downloading. If too many or too few, adjust the parameters. After splitting, trim individual segments to fine-tune start and end points, or add fade effects for smoother transitions.
FyleTools uses FFmpeg's silencedetect filter via WebAssembly to scan the audio waveform and identify silent regions based on your threshold and duration settings. The file is then split at each detected silence boundary and packaged as a ZIP archive. All processing happens locally.
