Quick Verdict
Use OGG (Vorbis) when…
AAC has broader device support and is used by every major streaming platform. OGG Vorbis is royalty-free and performs comparably well at mid-to-high bitrates.
Use AAC when…
Use OGG for open-source projects, games, and Linux-first workflows. Use AAC for maximum device compatibility — it works on everything from iPhones to cheap Bluetooth earphones.

Frequently asked questions
Does Spotify use OGG?
Yes — Spotify streams music using Ogg Vorbis (for desktop and older clients) and Ogg Opus (for mobile and newer clients). This is why downloaded Spotify tracks are in .ogg format. Spotify chose Vorbis/Opus because they're royalty-free and offer excellent quality at streaming bitrates.
Can iPhone play OGG files?
Not natively — iOS doesn't include an OGG decoder. VLC, CloudBeats, and other third-party apps can play OGG on iPhone. Apple Music cannot import OGG directly. If you need iOS-native playback, convert OGG to AAC (M4A) using FFmpeg or any audio converter.
Which sounds better: OGG or AAC?
At bitrates below 128 kbps, AAC has a clear quality advantage due to its more sophisticated perceptual coding. At 192 kbps and above, both are essentially transparent and the difference is imperceptible. Listening tests at 128 kbps consistently show AAC edges ahead of Vorbis.
Is OGG good for game audio?
Excellent for game audio in engines that support it. Unity and Godot both support OGG natively. The royalty-free nature makes it ideal for indie developers avoiding per-unit licensing costs. For iOS-targeted games, AAC is safer since iOS doesn't natively decode OGG and hardware acceleration only applies to AAC.
