What audio format should I use when publishing a game?

When publishing a game, your choice of audio format should be based on performance, compatibility, quality, and the type of audio content you’re using. Here is a streamlined recommendation to help you decide:

Primary Recommendation: OGG Vorbis (.ogg)

• Why?
• It provides a good balance of high-quality audio and smaller file sizes, making it suitable for background music, ambient sounds, and even dialogue.
• It supports embedded loop points, which are highly useful for seamlessly looping game tracks and ambient soundscapes.
• Widely supported in popular game engines like Unity and Unreal Engine.
• Open-source with no licensing fees.

When to Consider WAV (.wav):

• Why?
• Use WAV for sound effects that need fast response and maximum quality, such as UI sounds, weapon effects, or critical in-game actions.
• It is an uncompressed format, ensuring the highest sound quality with minimal CPU overhead for decoding.
• Caveat: Large file sizes can lead to increased memory usage, so use it sparingly for essential high-quality sounds.

Avoid (or Minimize) Use of MP3:

• Why?
• MP3 files offer good compression, but OGG generally provides better audio quality at similar file sizes.
• MP3 has a historical issue with licensing (though some patents have expired), and there is less robust support in game development tools compared to OGG.

Special Cases:

• FLAC (.flac): If you want lossless audio for a game that emphasizes extreme sound fidelity without concern for file size, consider FLAC. However, this is rare in most game projects.
• Platform-Specific Audio Formats: If your game targets specific platforms like consoles or mobile devices, check for any platform-preferred audio formats and convert accordingly for optimized playback.

Conclusion:

For most games, a combination of OGG Vorbis for music and ambient sounds and WAV for critical sound effects works best. OGG offers great compression, looping capabilities, and is highly compatible with modern game development tools, making it ideal for reducing file sizes while maintaining good audio quality. WAV should be used strategically for high-priority sounds that demand perfect quality and low latency.
