A podcast intro that runs ten seconds too long, a ringtone that needs the chorus and nothing else, a voice memo recorded too quietly, a meeting recording where the first two minutes are everyone joining the call. The audio editor above takes an MP3, WAV or M4A — or a video file, if the sound is trapped inside one — lets you select the exact range, adjust the volume and add a fade, then exports a clean file. No watermark, nothing to install.
Each row is a real job you can run with the controls above — select the range, set the effect, export.
| The fix | What you do | Controls |
|---|---|---|
| A ringtone from a song | You need thirty seconds of the chorus, not the whole track | Set Start and End around the section — export MP3 at 320 kbps |
| A loud or quiet recording | The file plays at half the volume of everything around it | Volume slider — up to 200% to lift it, 50% to tame it |
| An abrupt beginning or ending | Audio that cuts in hard or stops dead sounds unfinished | Fade in and Fade out — applied on export |
| A voice memo with dead air | Silence before the first word, after the last | Trim the Start and End to the spoken range |
| Sound trapped in a video | The interview only exists as an MP4 | Upload the video directly — the audio is extracted and editable in one pass |
Volume accepts 0–300% (100% is untouched); fades are applied during export. Uploads accept MP3, WAV, M4A, AAC, OGG and FLAC as well as common video formats. Limits checked October 2026.
Three steps in the browser — no DAW to install, no watermark on the export.
Drop in an MP3, WAV, M4A or another audio file — or a video, if the sound you want lives inside a recording. The preview loads in the page.
Drag the handles to keep the exact section, move the volume slider if the level is off, and tick Fade in or Fade out for a smoother start or end.
Choose MP3, WAV or M4A and press Export audio. Download the result — same session, no watermark, nothing to install.
Size depends on the output format more than on the edit. Same one-minute clip, four formats:
| Output format | Typical setting | ≈ Size per minute |
|---|---|---|
| MP3 | 160 kbps (page default) | ≈ 1.2 MB |
| MP3 | 320 kbps (top quality) | ≈ 2.4 MB |
| M4A (AAC) | 128 kbps | ≈ 1 MB |
| WAV (16-bit stereo, 44.1 kHz) | Uncompressed | ≈ 10.1 MB |
| Any format | Longer input, proportionally larger output | Size scales linearly with length |
WAV keeps every sample but costs about eight times the MP3. For sharing, MP3 at 160 kbps is the default here; WAV matters when the file will be edited again later.
The selected range is cut, the effects are applied, and the result is encoded once into the format you picked. A few details worth knowing before you start.
You keep one continuous section per pass — Start and End on the timeline. Chopping out a middle piece takes two exports; everything else is a single pass.
The slider (0–300%) is applied while the file is re-encoded, so the new level is baked in — no player settings to remember afterwards.
Fade in ramps the beginning up from silence; Fade out ramps the ending down. Both are applied to the exported file, not just the preview.
Upload a video and the sound is extracted first, then edited in the same job. If you only want the raw extraction with no edits, use the video-to-MP3 converter instead (linked below).
