WAV vs FLAC
WAV · Waveform Audio
WAV stores uncompressed, lossless PCM audio. It's the studio-grade choice for editing and mastering, but files are large (about 10MB per minute of stereo CD-quality audio).
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.
