The IBM Music Feature card is one of the original sound cards. This fairly expensive card includes an eight-voice stereo synthesizer and a complete MIDI interface. The heart of this card is the Yamaha YM-2164 sound chip, which can also be found in the Yamaha FB-01 MIDI Expander. Sound generation occurs through an FM synthesizer with multiple control parameters. There are also 240 preprogrammed sounds, including reproductions of traditional musical instruments.
Unlike LPC synthesizers, the Digitalker® was able to dynamically change sample rates at phone boundaries. This allowed fricatives (both voiced and unvoiced) to be played at a 13-kHz sample rate and normal voiced sounds to be played at a 10-kHz rate.
The N64's design is built around a Mips R4300i and a single coprocessor called RCP (Reality CoProcessor). This RCP contains not only a "Blitter" that handles the actual drawing, but also a general purpose DSP called RSP (Reality Signal Processor). The RSP is actually very well suited to process both 3D geometry and audio data.
