Frequently Asked Questions
How does M4A quality compare to FLAC?
At 256kbps AAC, the difference from FLAC is nearly imperceptible in normal listening. You lose the lossless guarantee, but the audible quality is excellent.
Will my FLAC metadata transfer to M4A?
Yes. M4A has excellent metadata support — title, artist, album, track number, and album art all transfer cleanly.
Is M4A the same as AAC?
M4A is the container file format, and AAC is the codec inside it. M4A files almost always use AAC compression. Think of M4A as the box and AAC as what's inside.
