BGM and Sound effect help

[uselessp]

Well, I'm quite troubled since I'm not experienced in finding any difference.

it's about the music type. Should I use the .ogg formatted type, or the .mp3 formatted type in music and sounds?
I can't find any difference, except how big and the quality of the sounds are.

If I uses Ren'Py, which one is better? Please tell me your opinions and your usual choices.

I haven't noticed a distinct difference between the formats myself. I would use whatever is easier for you.

MP3 is a commercially licensed format (Fraunhofer institute) whereas OGG is an open source format. Theoretically, if you make money with a game containing MP3 coded music, Fraunhofer can sue you for licensing fees. Therefore, use OGG.

*edit*
Moved this into asset creation, because turning music into digital form is also some sort of "creation".

Didn't know that about mp3s. Thanks for the tip, Taleweaver.

I prefer to use .ogg files for size reasons. I cut off at least 20MB from my latest visual novel by converting all of the .mp3 files to .ogg ones. I used Audacity to do that.
