About FLAC
FLAC (Free Lossless Audio Codec) compresses audio without losing anything: the files are typically half to two thirds the size of WAV and decode back to the exact original samples.
Music archives, CD rips and high-resolution downloads.
FLAC files are several times larger than MP3, and some older players and car stereos do not play them.

Why would anyone use FLAC when MP3 is so much smaller? FLAC stores the audio bit-for-bit with no loss at all, which matters for archiving and re-editing — the price is a file several times larger.
About M4A (AAC/ALAC)
M4A is an MPEG-4 audio file: the MP4 container holding only audio, usually AAC and sometimes Apple Lossless (ALAC).
Music bought on iTunes, iPhone voice memos and many podcast downloads.
Whether an M4A is lossy or lossless depends on the codec inside, which the file extension does not show.
Why convert audio to M4A? It wraps efficient AAC audio with chapter marks and cover art in one small file that Apple, Android and Windows all play.
