New technology for audio and music synthesis in multimedia PCs enriches the consumer experience and improves sound quality. This paper will present an overview of these advances and will also explain how they will be applied in practice. Wavetable synthesizers have replaced FM synthesizers and the latest generation supports downloadable sounds and 64-voice polyphony. The Windows operating system supports three APIs for music and audio in games: DirectSound, DirectSound3D, and DirectMusic. The system hardware supports higher quality through AC97 and higher performance through MMX. This new technology provides new capabilities for game developers and it enables new applications for sound in PCs.
