About FLAC (Free Lossless Audio Codec)
Lossless compression: identical audio quality to WAV at roughly half the file size. FLAC is the go-to for archiving music collections and delivering masters, and it's the required upload format for several distribution platforms. It supports embedded metadata and album art, which WAV handles poorly.
Best for: archiving, music distribution, audiophile listening

M4A vs FLAC: what changes?
M4A is a lossy compressed format, while FLAC is lossless. Converting to FLAC will not restore quality that M4A compression already discarded — but it gives you an editing-safe, universally compatible file that won't degrade further with processing, which is exactly what studios, DJs, and mastering engineers need.
