FLAC vs AAC
FLAC · Free Lossless Audio Codec
FLAC is lossless but compressed — bit-perfect quality at roughly half the size of WAV. It's the audiophile and archival favourite, supported by most modern players.
AAC · Advanced Audio Coding
AAC is the lossy codec inside most .m4a files and streaming audio. It sounds better than MP3 at the same bitrate, but isn't as universally playable on older or non-Apple hardware.
