Audio Encoding
From The Official Visionaire Studio: Adventure Game Engine Wiki
Visionaire supports the Ogg Vorbis and Opus audio formats. Both are open file formats and (unlike MP3) unencumbered by patents. Their lossy compression algorithms lead to good quality sound files with pretty small file sizes.
Tools
We recommend using Audacity for audio conversion as it is a free, open-source audio editing suite and conversion tool that supports many audio formats. It also supports tag embedding and imports/exports fairly quickly.
To save your sound in one of the aforementioned formats, use "File > Export Audio..." and choose your preferred audio format and quality.
