+Unity has many different asset file types that can be imported to use for a game

+important formats are the audio, text and sprite formats.

+\subsection{Audio Format}
+
+% TODO: +ref (both urldate 2024-09-12)
+The choice of audio format for the cr\^epe game engine depends on several factors,
+including sound quality, memory usage, and licensing. According to various sources
+\href{https://dev.to/tenry/comparison-of-audio-formats-for-games-jak}{comparison audio formats},
+\href{https://www.universityofgames.net/articles/audio-file-formats-used-in-game-development/}{Audio files in games},
+the most commonly used audio formats in game development are WAV, MP3, and Ogg.
+
+\subsubsection{Licensing}
+
+Historically, MP3 had patents on the audio format, but these restrictions have
+expired. Ogg and FLAC, both developed by Xiph.Org, are open-source formats.
+Additionally, the WAV format, though widely used, does not require a specific license
+for distribution.
+
+\subsubsection{Conclusion}
+
+For the cr\^epe game engine, Ogg and FLAC are the preferred audio formats due to
+their open-source licenses and high compatibility. FLAC is ideal for high-quality
+audio with minimal compression, while Ogg is better suited for lower-quality audio
+that requires reduced memory usage. Both formats come from the same non-profit
+organization, Xiph.Org, ensuring that they align with open-source values and
+licensing flexibility.
