High-fidelity software reimplementations of the MOS6581 and MOS8580 SID chips.

This package contains the core SID emulation engines derived from the work of Dag Lem and Antti S. Lankila. The emulation aims for cycle- accurate reproduction of the analog and digital characteristics of the original Sound Interface Device (SID) used in the Commodore 64 and related systems.

Contents and Functionality

  • Accurate digital emulation of 6581 and 8580 SID variants
  • Runtime configuration of chip parameters such as filter curves, distortion models, and sampling modes
  • High-quality resampler to match playback or recording sample rates
  • Integrated SID mixer for combining output from multiple SID instances
  • Support for stereo and multi-SID configurations, reflecting modern C64 music production practices

Even though a stock Commodore 64 contains only one SID chip, this emulator supports setups with multiple SID units for stereo or extended audio scenarios. Such configurations are commonly used by contemporary musicians and cartridge-based sound extensions.
