About WAV
Waveform Audio File Format
A RIFF-based audio format from Microsoft and IBM, released in 1991, that almost always holds uncompressed PCM. CD-quality stereo takes about 10 MB per minute. Use it for editing, mastering and tools that want uncompressed audio; convert away from it to save space.
About AAC
Advanced Audio Coding
The lossy codec standardized in MPEG-2 and MPEG-4 as a successor to MP3, generally sounding better at the same bitrate. A .aac file is a bare ADTS stream without the MPEG-4 container an M4A has. Use it for players and streaming tools that want a raw AAC stream; for a music library, M4A holds the same audio with better tagging.
