MP3 to OGG FAQ

Vorbis or Opus: which should I choose?

Vorbis has the widest support in game engines and older software. Opus is more efficient, especially for speech and at low bitrates, and is ideal for web and messaging use.

Why does the Opus file end in .opus.ogg?

Opus audio is stored in an Ogg container. The double extension makes the codec obvious; you can rename it to .opus or .ogg as your software expects.

Will quality improve over the MP3?

No. Converting from MP3 cannot restore detail. The aim is format compatibility; choose High quality to avoid adding audible loss.

Does Safari play OGG?

Recent versions of Safari play Opus and Vorbis in many cases, but support has historically been limited. For web audio, provide an MP3 or AAC fallback.

Why do game engines like OGG?

Vorbis is free of licensing fees, decodes efficiently, loops seamlessly without the gaps MP3 can introduce, and has long been the standard compressed format in engines such as Unity and Godot.

What bitrates do the quality levels correspond to?

For Vorbis, High is quality 7 (about 224 kbps), Balanced is quality 5 (about 160 kbps) and Small is quality 3 (about 112 kbps); the actual bitrate varies with the music. For Opus, the levels are 160, 112 and 64 kbps. Opus at 112 kbps is roughly comparable to MP3 at 192 kbps.

Why convert to OGG

Ogg Vorbis is a staple of game development. It carries no licensing fees, decodes quickly, and, unlike MP3, can loop seamlessly because it does not add padding at the start and end of a file. That makes it the natural choice for background music and ambient loops in game engines.

Opus is the more modern option. It combines techniques from speech and music codecs, so it handles voice exceptionally well at low bitrates while remaining excellent for music. Web browsers use it for calls, and it is a strong choice for any audio delivered over the internet.

Quality settings differ between the two. Vorbis uses a quality scale where 5 corresponds roughly to 160 kbps; Opus is configured by bitrate, and 112 kbps is already transparent for most stereo music.

Because the source is an MP3, quality cannot exceed the original. If you have WAV or FLAC originals, convert from those for the best OGG files.
