About this tool
Cutting the dead air off a voice memo, layering narration over background music, joining two recordings; small audio jobs that don't deserve a desktop audio workstation. This editor handles them in the browser: upload clips, trim each one's start and end, arrange and overlap them, preview the mix, and export.
Clips can overlap in time, which is what makes it a mixer rather than a splicer: a music bed under a voice track is simply two overlapping layers. Export renders the mix to a WAV file; uncompressed and universally accepted, so nothing is lost at the final step.
How to use it
- Upload one or more audio clips (MP3, WAV, M4A, AAC, OGG, FLAC).
- Trim each clip's start and end times to cut silence and fumbles.
- Arrange clips in sequence or overlap them to layer tracks.
- Preview the mix and tweak it until it sounds right.
- Export; the browser renders the mix to a WAV file on your device.
Tips
- Trim the silence off the front of voice recordings; it's the single most audible improvement per second of effort.
- Layering music under speech? Quiet, steady music works; anything with its own vocals fights the voice.
- WAV output is large and lossless. Convert a copy to MP3 at the final step if a smaller file is needed.
FAQs
Can I join multiple recordings into one file?
Yes; arrange the clips in sequence and export; the WAV contains them in order.
Can I put music under a voice recording?
Yes. Add both files and overlap them in time; the export mixes the layers together.
Why does it export WAV instead of MP3?
The browser can render the mix to an uncompressed WAV master without another lossy encoding step. Most audio software accepts WAV; convert a copy if your destination requires another format.
Are my recordings uploaded while editing?
No. Decoding, mixing, and rendering all run on your device through the browser's audio engine.
