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. + +\paragraph{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. + +\paragraph{Conclusion} For the Crepe 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. + + \subsection{Conclusion} \section{Rendering} |
