WAV. WAV stores raw PCM samples with no compression at all. What you save is exactly what the editor sees, which is why studios and editors use it.
FLAC. FLAC compresses audio like a ZIP file compresses text: the file gets 40–60% smaller, and every sample comes back bit-for-bit identical on playback.
What happens to quality
Both are lossless, so the FLAC file holds exactly the same samples as the WAV. Nothing is lost. Hear the difference between lossless and MP3 yourself.
