Frequently Asked Questions
What is OGG format?
OGG is a free, open-source container format that typically uses Vorbis for audio compression. It offers quality comparable to MP3 and AAC but is completely patent-free.
What quality level should I use?
Quality 6 (≈192 kbps) provides excellent quality for most uses. Quality 8-10 (≈256-320 kbps) offers near-transparent quality. Lower levels (3-5) are good for web streaming where bandwidth is limited.
Is OGG better than MP3?
OGG Vorbis typically provides better quality than MP3 at equivalent bitrates. However, MP3 has wider device compatibility. Use OGG for open-source projects or when quality per file size is critical.
What devices support OGG?
OGG is supported by most modern browsers, Android devices, and many media players. Support on Apple devices (iPhone, iPad) is limited. Windows and macOS need third-party players for best support.
Can I use OGG for commercial projects?
Yes! OGG Vorbis is completely free and open-source with no licensing fees or patents, making it ideal for commercial use, especially in games and open-source applications.
