AMR is the narrowband codec old phones recorded voice memos in, and barely anything plays it today. AU is the legacy Unix audio format some scientific and telephony tooling still reads, so converting turns a file you are stuck with into one you can actually use. Morphix runs the whole AMR → AU conversion locally with WebAssembly, so even confidential material never leaves your device.
Drop your AMR file above and Morphix decodes it locally, then re-encodes it as AU 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.
