Audio trimmer
This audio trimmer works by take rather than by timeline: record, listen back, and keep only what is worth keeping. The fumbled attempts never reach your downloads folder.
Ready. Press Record and allow microphone access when your browser asks.
Review before you save
The most useful trim is the one you make by not saving a bad take at all. Each recording appears below the controls with a player and two buttons: Download keeps it, Discard removes it from memory immediately. Record as many attempts as you need and only download the one that worked.
This is the browser-based approach to editing: rather than capturing a long take and cutting it up, capture in usable pieces and throw away the misses. For most speech recording it is faster than any timeline editor.
Practical trimming technique
- Start recording before you start talking. Two seconds of room tone at the head gives you something to fade from, and it is easier to remove than to invent.
- Clap or tap once if you plan to edit later. A sharp transient is instantly visible in any waveform editor and makes alignment trivial.
- Pause instead of stopping when you fluff a line. Pause, collect yourself, resume, and repeat the sentence — you get one continuous take with a repeated line rather than fragments to reassemble.
- Leave the last breath in. Cutting immediately after the final word sounds abrupt; half a second of silence sounds finished.
When you need a real editor
This page handles record-review-keep. It does not do waveform-level editing, fades, noise reduction or multi-track mixing. For those, download a WAV file from here and open it in Audacity, which is free, open source, and available on Windows, macOS and Linux. Starting from uncompressed audio means the editor has the full signal to work with.

Questions
Can I cut a specific section out of the middle of a recording?
Not on this page — it works on whole takes rather than a timeline. For cutting sections, download a WAV and open it in Audacity, which handles that in a few seconds and is free.
Can I upload an existing file to trim?
No. This page records and trims within one session. Since nothing is ever uploaded, there is no file-handling path for audio that did not originate here.
What happens when I press Discard?
The take is removed from the page and its memory is released immediately. It was never stored anywhere else, so that is the end of it — there is nothing to undo.
How many takes can I record in one session?
As many as your device's memory allows, since each one is held in RAM until you download or discard it. Clearing takes you do not need keeps things responsive during a long session.
Which format should I record in if I plan to edit later?
WAV. Editing a lossy file and re-exporting it means two rounds of compression on the same audio. Starting uncompressed avoids that entirely.
