Converting M4A to FLAC: what to know
M4A is converted to FLAC when a player, program or platform accepts only FLAC, or to keep a recording in a lossless format for editing.
If the M4A holds AAC, which is lossy, FLAC won't improve it: the sound stays as it is, with no new loss, but the file becomes several times larger. If the M4A holds ALAC (Apple Lossless), the conversion to FLAC is fully lossless.
M4A or FLAC: which to choose?
M4A (MPEG-4 Audio)
M4A is an MPEG-4 audio file, usually AAC - the format of Apple Music, iTunes and iPhone voice memos.
Best for music and voice recordings in the Apple ecosystem.
FLAC (Free Lossless Audio Codec)
FLAC compresses audio without any loss: CD quality at roughly half the size of WAV.
Best for music archives and listening in maximum quality.
What happens when converting M4A to FLAC
Converting to FLAC will not restore the quality lost in M4A - the file will only get bigger. It makes sense when a program requires FLAC.
Trim the fragment, convert stereo to mono or change the sample rate.
M4A files up to 512 MB are supported; the actual limit also depends on the free memory of your device.
