AMR is the narrowband codec old phones recorded voice memos in, and barely anything plays it today. AAC sounds better than MP3 at the same bitrate and is the default codec on Apple devices, so converting turns a file you are stuck with into one you can actually use. Morphix runs the whole AMR → AAC 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 AAC 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.
