Why Convert AAC to OGG?
Converting AAC to OGG is needed for platforms and applications that require the open-source OGG format, such as game engines and Linux-based media players.
About the AAC Format
AAC is a lossy audio codec that delivers better sound quality than MP3 at the same bitrate. It is the default audio format for Apple products, YouTube, and many streaming services. AAC at 128kbps is generally considered equivalent to MP3 at 160kbps.
AAC was developed as part of the MPEG-2 standard in 1997 and later enhanced in MPEG-4. Apple adopted it as the default iTunes and iPod format, which drove widespread adoption. Today it's used by YouTube, Apple Music, and most streaming platforms.

Disadvantages
- Less universally supported than MP3 on older devices
- Still lossy — not suitable for archival
