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.
About WMA
Windows Media Audio
Microsoft's audio codec family, introduced in 1999 and stored in an ASF container, with lossy, lossless and voice variants. Convert from WMA to play old Windows Media files on phones, Macs and players that never supported it.
