Audio Merger
Join several audio files into one, in the order you choose, with optional silence between them.
Processed in your browser: your files are never uploaded.
The video engine (FFmpeg) downloads once, about 31 MB, and then works offline in this tab. Processing runs on your own device, so long or 4K videos can take a while; keep the tab open until it finishes.
Audio Merger
Combine voice notes, podcast segments, songs or sound effects into one file. Add as many files as you like, put them in order with the arrows, choose whether to leave a short silence between them and the format to save in. Files with different formats, sample rates and mono or stereo are matched automatically.

Frequently asked questions
- Can I mix different formats?
- Yes. MP3, WAV, M4A, OGG, FLAC and others can be combined; they are converted to the same sample rate and stereo first.
- Is there a crossfade?
- Not yet; the files play one after the other, with the gap you choose.
- Are my files uploaded?
- No. The video engine runs in your browser, so your files stay on your device. Only the engine itself (FFmpeg, about 31 MB) is downloaded, once.
