M4A 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.
M4A is an audio format that usually holds AAC-encoded sound in an MP4 container. It is Apple’s standard for music downloads and voice memos, offering great quality at small sizes and playing natively across the Apple ecosystem.
M4A plays in Apple Music/iTunes, QuickTime, VLC and most modern media players; on older devices, convert it to MP3.
