C64 SID Phase Accumulator and FPGA Tuning

In this video, Jeri Ellsworth explains the phase accumulators in the c64 SID sound chip. This technique was used in many early synthesizers and sound chips. Jeri Ellsworth is most known for creating the C64 DTV, the all in one joystick emulator in 2004. She is also responsible for designing the FPGA chip of the C-One, so I guess no more introduction is needed, enjoy this master lesson.



Use an FPGA to tune a secondary SID chip to give the C64 a pseudo stereo effect. This demo shows how you can play ordinary chip tunes as if they had stereo channel differences.
