About Split Audio
Parts are copied from the original without re-encoding, so they keep the original quality. Each part is written to your device as it is made, so long recordings work on phones too.
Processing happens in this tab with FFmpeg compiled to WebAssembly; your recordings are never uploaded. The first video or audio tool you use downloads the 10 MB engine once and keeps it cached for next time. On phones, files are processed one at a time to stay within memory, and long recordings take a little longer. Keep the tab open until the download appears.
