What is a WAV file?
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.
How to open a WAV file
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.
