What the tool does, how to run it, and what to expect from the result.
Add the voice notes you want to combine, in any format, put them in the order you want them to play, and export one MP3. Each note is decoded by its own real codec before joining, so a WhatsApp .opus note, an iPhone .m4a memo, and an Android .amr recording can sit in the same queue and merge cleanly into one file.
Everything happens in the browser tab. The recordings are never uploaded, the joining is local, and the download comes out of memory.
