Drop a recording, drag the handles around the part you want, and the cut is made on your device.
Trim audio in your browser — cut the silence off the front of a recording, pull one answer out of an hour-long interview, or clip a ringtone out of a track you own. Set the start and end points, preview with the built-in player, and GhostAudio cuts the file on your device. No upload, no signup, no watermarked output. Meetings, memos, and interviews stay on your machine.
Trimming is the most common edit anyone makes to audio: cutting dead air from the start of a recording, pulling a single quote out of an interview, or shortening a clip to fit a length limit. Doing it in a browser avoids the usual friction of installing an editor for a thirty-second job, and because the processing is local, sensitive recordings — interviews, meetings, voice notes — never leave your machine.
Drop your audio
Drag in an MP3, M4A, WAV, or OGG. It opens in the GhostAudio studio with the Trim surface ready.
Set the in and out points
Enter the start and end times in seconds, using the built-in player to find them — all locally in your browser.
Download the clip
The cut is made on your device and the trimmed audio downloads immediately.
Trimming is lossless
The cut is a stream copy (ffmpeg `-c copy`) — the original container and codec are kept and nothing is re-encoded, so there is no generation loss even on an already-compressed file. The frame-boundary note below is a direct consequence of that.
Cuts land on frame boundaries
Compressed audio is stored in frames, so a cut may fall a few milliseconds from the exact timestamp you set. This matters only for precise musical edits, not for speech.
Long files are memory-bound
The whole file is processed in your browser, so a multi-hour recording may exceed what a phone can hold. Trim on a desktop for long sources.
Is my recording uploaded?
No — playback and the cut both happen in your browser. There's no upload endpoint for the file to go to.
Does trimming re-encode the audio?
No. The cut is a stream copy — ffmpeg keeps the original container and codec and re-writes only the section you asked for, so there's no second compression generation and no quality loss at all. Cuts snap to the nearest frame boundary, which is a consequence of not re-encoding.
Can I cut out the middle of a file?
One range per pass — to remove a middle section, trim the two halves you want in two passes. Each pass takes seconds.
Can I convert and trim together?
Yes — the studio chains steps: convert an M4A to MP3, then trim the result in the same tab.
Can I remove a section from the middle?
This tool keeps a single continuous range. To drop a middle section, trim the two parts you want to keep and join them, or use a full editor if you need many cuts.
Is the original file modified?
No. The trim produces a new file and the original on your disk is untouched — nothing is written back and nothing is uploaded.
Every GhostAudio tool runs entirely in your browser. Your file is never uploaded — there's no upload endpoint to send it to.
