The audio chip of the SNES was designed by him and Sony.
The Nintendo S-SMP is the audio CPU of the SNES video game console.
The SNES contains a sound module called APU (Audio Processing Unit) which is almost completely separate from the rest of the system: it is clocked at a nominal 24.576 MHz in both NTSC and PAL systems, and can only communicate with the main board via 4 registers on Bus B. It was designed by Ken Kutaragi and manufactured by Sony, who subsequently entered the video game console industry with its PlayStation brand.
