Why games use OGG

OGG Vorbis is an open format from the Xiph.Org Foundation, free to use with no licence fees. That's why game engines, mods, and open-source apps chose it: Unity and Godot import it, Minecraft's sounds are OGG files, and RPG Maker reads it too.

An MP3 becomes an OGG at about the same bitrate, so the file stays about the same size and sounds the same. For voice lines and chat apps, pick Opus instead: it's newer, and it sounds clearer than Vorbis at low bitrates.

Questions

Is it OGG Vorbis or Opus?

OGG Vorbis: the .ogg file games and most apps expect. For Opus, the newer format made for speech and small files, pick Opus under Convert to, and you get an .opus file.

Will it work in Unity, Godot, or Minecraft?

Yes. Unity and Godot both import OGG Vorbis, and a Minecraft resource pack needs its sounds as .ogg files holding Vorbis, which is what you get here.

Does it lose quality?

A little, in theory: MP3 and Vorbis both leave out detail, so going from one to the other drops a bit more. The OGG keeps about the MP3's bitrate, and most people can't tell them apart. If you still have the original WAV or FLAC, convert that instead.

How big will the OGG be?

About as big as the MP3, since it keeps about the same bitrate. For smaller game sounds, set a lower bitrate under More options, such as 96 kbps.

Can I set the sample rate?

Yes, under More options, from 8,000 to 48,000 Hz. Leave it, and the OGG keeps the MP3's, usually 44,100 Hz.

Is it free?

Yes, for the first hour of each file, 10 times a day, with no sign-up. For longer files, see pricing.

What happens to my files?

They stay private. Files are deleted after 24 hours, and free results after 1 hour.
