AAC uses lossy audio compression. It usually saves space, but some audio information is discarded when WAV is encoded.
WAV is an audio container that commonly stores uncompressed PCM sound. PCM keeps the encoded samples without lossy compression, which is useful for editing and mastering but usually creates much larger files than MP3 or AAC.
WAV is supported by common media players and audio editors, including Windows Media Player, QuickTime and VLC. Support can depend on the codec stored inside the file.
AAC (Advanced Audio Coding) is the successor to MP3, delivering better sound at the same file size. It is the default for Apple Music, YouTube and most streaming services, and is supported across virtually all modern devices.
AAC plays in Apple Music/iTunes, QuickTime, VLC and on nearly all modern phones, browsers and players.
