Trim audio to the seconds you need

Keep only the stretch of a recording you care about, such as one answer from an interview, a ringtone, or a voice memo without its silent opening.

    Updated

    To trim audio, drop the file, enter where the clip should start and how many seconds it should last, then download the shorter file. Everything outside that window is removed, and the clip keeps the format of the original.

    Trimming runs on our servers in Germany rather than in your browser. Files arrive over an encrypted connection, and we delete them automatically within two hours. We accept M4A, AAC, OGG, Opus, WMA, MP3, WAV and FLAC.

    How to cut a clip from a recording

    1. Drop the recording, or several recordings, onto the page.
    2. Type the start point in seconds.
    3. Type the number of seconds the clip should run.
    4. Click Trim, then save the clip or a ZIP of every clip.

    Writing the start and the length

    Both boxes take seconds, and decimals are allowed. To start at a minutes-and-seconds mark, multiply the minutes by 60 and add the seconds, so 2:30 becomes 150. A start of 150 with a length of 45 keeps everything from 2:30 to 3:15. A start of 12.25 begins a quarter of a second after the 12-second mark.

    The length is 30 seconds unless you change it. That is also the usual upper limit for a phone ringtone, so for a ringtone the start time is often the only field to fill in.

    Precision, clicks and quality

    We decode the chosen section and save it again. That puts the cut exactly where you asked, to a fraction of a second, instead of snapping it to the closest chunk of compressed audio. The edges get no fade, though, so cutting straight through a loud passage may leave a small click at either end. Cut in a quiet moment where possible.

    WAV and FLAC stay lossless. Clips in Opus, OGG, M4A, AAC or MP3 are encoded a second time with high-quality settings: Opus at 128 kbps, M4A and AAC at 192 kbps, and MP3 at variable bitrate quality 2, usually 170 to 210 kbps. At those settings the extra encode is not audible in normal listening. For a file that needs several rounds of edits, turn it into WAV first and do the trimming on that copy.

    One cut across a whole folder

    Some jobs repeat the same cut on many files, such as removing the ten-second countdown at the top of every episode of a show. Drop the files together, or drop the folder, instead of trimming them one by one. Without an account a batch takes up to 5 files of up to 50 MB each, within 20 server jobs a day. A free account allows 10 files per batch and 50 jobs a day, and Pro allows 500 files of up to 500 MB with no daily allowance. Download the clips individually or as one ZIP.

    The pipeline builder goes a step further. It trims a whole folder in one run and can pass the clips on to another tool, such as a format conversion. Pipelines are free to try on up to 3 files.

    FAQ

    Can I keep two separate parts of one recording?

    Each run keeps one section. Cut the parts one at a time, then combine the clips with merge audio.

    Will the clip fade in or out?

    No. The tool makes a straight cut, so pick quiet points for the start and the end.

    How do I make a ringtone that needs the .m4r extension?

    Keep the clip at 30 seconds or shorter, turn it into an M4A file with convert audio, and change the file ending to .m4r.

    What if the sound sits inside a video?

    Trim video cuts picture and sound together. To keep only the sound, extract the audio from the video first and trim that file here.
