AU is a Unix-era format that essentially no modern player opens. Converting to MP3 makes those old recordings playable on any phone, browser or car stereo, and shrinks them dramatically at the same time.
Drop your AU file above and Morphix decodes it locally, then re-encodes it as MP3 using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Batch as many files as your machine can handle.
