The balancing act between pristine sound quality and not making your game take up 200 GB.
Audio compression in games refers to reducing file sizes of sound assets while maintaining acceptable quality. Uncompressed audio (WAV/PCM) sounds perfect but devours storage -- a single AAA game might have 50+ hours of voice dialogue, thousands of sound effects, and hours of music. Formats like Vorbis (OGG), Opus, and platform-specific codecs compress audio by removing frequencies humans are less likely to notice. The tricky part is that different sounds need different compression levels: music and dialogue benefit from higher quality, while short combat sound effects can be compressed aggressively without noticeable loss. Streaming larger files from disk while keeping frequently used sounds in memory adds another layer of optimization.
Example
Modern Call of Duty titles have famously massive install sizes partly due to high-quality audio assets -- Warzone's audio alone accounted for a significant chunk of its 100+ GB footprint. Meanwhile, indie games like Hollow Knight use clever compression and asset reuse to deliver a rich soundscape in under 1 GB.
Why it matters
Audio compression directly affects every player's experience through download sizes, load times, and storage requirements. It's a constant negotiation between the audio team wanting pristine quality and the engineering team trying to keep the game installable on consumer hardware.
