About this tool
- Where it runs
- On the server: a browser cannot do this kind of work. The file is uploaded only for as long as the job takes and deleted right after — two hours without an account, twenty-four hours with one.
- What it accepts
- audio, M4A, OPUS, AAC, WMA. The type is determined by the file contents, not by its extension.
- Limits
- Up to 10 files at a time, each up to 200 MB, 500 MB in total.

- Extract audio from videoPull the soundtrack out of a video file. When the track can be lifted as is, nothing is re-encoded and nothing is lost.
- Trim audioCut a fragment out of a recording by timecodes. By default the stream is copied, so the cut costs no quality.
- Normalize loudnessEven out loudness to the EBU R128 broadcast standard, in two passes — so the recording does not breathe.
- Merge audioJoin several recordings into one, in the order you picked. Matching files are joined without re-encoding — instantly and with no quality lost.
- Trim silenceCut the silence at the start and the end of a recording. Pauses inside are left alone — in speech they carry meaning.
- Edit audio tagsChange the title, artist and album. The audio itself is copied untouched, so nothing is lost and it takes no time.
