Audio Splitter
Trim audio by setting start and end times. Free, no signup, no upload.
How It Works
Select an audio file, set the start and end times in seconds, and click Trim. The selected segment is extracted and encoded as a WAV file. You can preview it and download the result. No file is ever uploaded to a server.
Why Split Audio?
Audio splitting is useful for extracting a specific section from a recording — a favourite part of a song, a clip from a podcast, a voice memo segment, or trimming silence from the beginning and end of a recording.
Tips for an Accurate Cut
Use the built-in player to scrub to the exact moment your segment should start and end, then type those seconds into the start and end fields — decimals like 12.5 are allowed for finer control. To trim only the end, leave the start at 0; to trim only the beginning, leave the end at the full duration. Preview the result before downloading, and re-run with adjusted times if the cut is slightly off. To make several clips from one file, trim and download one range at a time.
Frequently Asked Questions
How do I split or trim an audio file online?
Select an MP3 or WAV file, then enter the start and end times in seconds for the part you want to keep. Click Trim Audio and the tool extracts that segment, which you can preview and download as a WAV file.
How do I know which start and end times to enter?
When you load a file, a player appears so you can listen and note the seconds where your segment begins and ends. The end time is pre-filled with the full duration, so you only need to adjust the values to your chosen range.
Can I split a WAV file, not just MP3?
Yes. Both WAV and MP3 files are supported. Whatever the input, the trimmed segment is exported as a WAV file named after your original file with -trimmed added.
Why do I get an invalid time range error?
The end time must be greater than the start time, the start cannot be negative, and the end cannot exceed the file's total length. Adjust the values so they describe a valid segment inside the file and try again.
Is my audio uploaded to a server?
No. The file is decoded and trimmed entirely in your browser using the Web Audio API. Nothing is uploaded, so your audio never leaves your device.
