What is AAC?
AAC (Advanced Audio Coding) is the successor to MP3, delivering better quality at the same bitrate. It powers YouTube, streaming radio, and most Apple audio.
Why convert AAC to MP3?
Raw .aac streams are not recognised by every player. MP3 remains the most compatible format, so converting guarantees the file opens wherever you need it.
Quality notes
Encoding uses LAME at high VBR quality. Since AAC and MP3 are both lossy, a re-encode loses a little fidelity — retain the source where possible.
