About Extract an Audio Section
Pulling out a specific section of a longer audio file — a favorite part of a song, a relevant clip from a recording, a segment to share separately — is one of the most common audio editing needs, and doesn't require a full audio editor to accomplish. This tool reads a file's actual duration automatically once uploaded, then lets you set precise start and end times before cutting.
A real FFmpeg build compiled to WebAssembly performs the cut entirely inside your browser, decoding the selected time range and re-encoding it as MP3 — this guarantees the cut points land exactly where you specify, rather than being limited to wherever the nearest natural boundary in the original file happens to fall.
Start and end times are entered in minute:second format with input validation preventing an end time set before the start time — catching the most common mistake before wasting processing time on an invalid range.
The output is always a fresh MP3 encode of just the selected section — the rest of the original file is discarded entirely, not merely hidden, so the result contains only the portion you chose to keep.
How it works
- Upload your audio file. Duration is detected automatically.
- Set start and end times. Enter exact minute:second boundaries for the section to keep.
- Cut and download. Just that section, re-encoded as MP3.
