AU is a Sun-era audio format that survives in old Unix and academic archives and almost nowhere else. W64 is Wave64: uncompressed audio without WAV's 4 GB size ceiling, built for long live recordings, so converting turns a file you are stuck with into one you can actually use. Morphix runs the whole AU → W64 conversion locally with WebAssembly, so even confidential material never leaves your device.
Drop your AU file above and Morphix decodes it locally, then re-encodes it as W64 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.
