Per common compression formats, OGG VORBIS and OPUS for game audio offer which key advantage over WAV/PCM?
AMuch smaller file size (lossy) for music + speech
BBit-exact lossless reproduction of waveforms
CAlways faster decode than PCM playback
DHardware-only decoding on specific chips
Answer & Solution
Correct answer: A. Much smaller file size (lossy) for music + speech
Vorbis + Opus: lossy perceptual codecs achieve ~10× compression of PCM at near-transparent quality. Used by Unity / Unreal for music and SFX.
