Why source format won't open
Most "won't open" issues are format mismatches (the extension says source format but the bytes say otherwise) or unsupported variants (a specific sub-flavor of source format the receiver's software doesn't handle).
Converting to target format with Convert Audio re-encodes the content into a clean, standards-compliant file. Whatever weirdness the original had, the output of Convert Audio is a fresh, well-formed target format.
