Why convert AAC to MP3
AAC is efficient and common on phones and streaming, but raw .aac files can confuse older players, car stereos and some DJ software.
Converting to MP3 gives you a file that plays on practically everything.
Older hardware
Car stereos and MP3 players that skip AAC.
Video exports
Audio pulled from video is often AAC.
DJ libraries
Keep a consistent MP3 library.
AAC to MP3 quality
Both are lossy, so a small extra loss happens. Encoding at 320 kbps keeps it minimal.
If you have the original WAV or FLAC, convert from that instead.
