What is AAC?
AAC is the successor to MP3 and generally sounds better at the same bitrate. It is the audio format behind Apple Music, YouTube and most MP4 videos, and it is supported by all modern phones and browsers.
What is OGG?
OGG is an open, patent-free container most often used for Vorbis or Opus audio. It gives good quality at low bitrates and is common in games, web apps and Linux software, but many car stereos and Apple devices do not play it.
Tips for converting AAC to OGG
- Converting a compressed file such as MP3 to a lossless format does not restore detail already removed; it only makes the file larger.
- For music, a lossless source (WAV or FLAC) gives the best result when you convert to OGG.
- Check that your player, car stereo or editing app supports OGG before converting a whole library.
- Keep the original AAC file as a backup until you are happy with the converted audio.
