Audio Encoding
From The Official Visionaire Studio: Adventure Game Engine Wiki
We recommend using .ogg (vorbis) as your audio format with Visionaire Studio. We also recommend Opus but it currently isn't directly supported by Audacity, so I will not be including any more information about it on this page, for now.
The reason we recommend both .ogg (vorbis) & opus formats for audio is because they are both open source formats, both have good sound quality & the compressed file sizes are pretty small. Other formats may require you to purchase various licenses to use them commercially or with intent to make money etc. See here for more information about .ogg (vorbis) & here for more information about opus.
