The remixer accepts MP3 or WAV uploads up to 50 MB; the page says the file stays in the browser until generation. It offers MP3 and WAV downloads and describes the stereo mix as royalty-free. Lyrics and vocals are supported in English, Spanish, Japanese, Korean, and Chinese. The page says a full 2–3 minute remix typically renders in roughly 20 seconds, depending on duration and quality settings.
