M4A hides AAC audio inside an MP4 container, which some hardware players refuse to open. AC3 is the surround codec home-theatre receivers, DVD authoring tools and broadcast chains expect, so converting turns a file you are stuck with into one you can actually use. Morphix runs the whole M4A → AC3 conversion locally with WebAssembly, so even confidential material never leaves your device.
Drop your M4A file above and Morphix decodes it locally, then re-encodes it as AC3 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.
