Why convert M4A to WAV?
WAV is a plain, uncompressed format — the file will likely be larger than the M4A original, in exchange for maximum compatibility. The main reason to convert M4A to WAV is compatibility: WAV plays on virtually any device or app without an extra codec, while M4A doesn't always. If you're sharing a file with someone else, sending it to a tool that expects a specific format, or archiving it for the long term, WAV is usually the safer target.
