Two very different M4A files hide behind the same name.
An .m4a can hold AAC, which is lossy like MP3, or ALAC, Apple's lossless format. Converting ALAC to FLAC is a perfect copy. Converting AAC to FLAC makes a much bigger file that sounds exactly the same as the M4A. Pick your file's source to see which case you're in.
Open songs, voice memos or old archives and save them as MP3, AAC, FLAC, Opus, WMA, AC3, AMR or any of 19 more. Pick a quality preset or an exact bitrate, convert the whole batch in one pass, then download each file or one ZIP.
ffmpeg -i input.wav -vn -map_metadata 0 -ar 48000 -ac 2 -c:a libmp3lame -b:a 192k -f mp3 output.mp3FLAC stores a fingerprint (an MD5 checksum) of the decoded audio. After converting an ALAC file, we decode both and compare fingerprints. If they match, every sample is identical: not "sounds the same", provably the same.
M4A stores song details in short four-letter codes; FLAC uses plain-text names. Most map exactly. A few Apple-only extras don't have a FLAC equivalent.

Depends which formats. Lossless in, lossless out, and the file you get back is identical. Convert to something compressed and you trade a little quality for a smaller file, which is usually the trade you wanted.
