Questions about MP3 and OGG.
Check the format behavior, limitations, and follow-up options before processing a real file.
OGG Vorbis is the audio format many game engines, modding tools, and open-source projects expect — it's patent-free and streams well. If a project asks for .ogg, converting your MP3 gets it there. Both formats are lossy, so keep the conversion count low and pick the High setting if the file will be processed again downstream.
