Stereo (Phonics) – C64 Demoscene on Commodore 64 Ultimate with REAL 8580 R5 SID Chip

Stereo by Phonics is a polished Commodore 64 demoscene production known for its clean design, tight pacing, and strong audio‑visual sync. Released at the X demoparty, it stands out as one of the more memorable Phonics releases thanks to its smooth transitions and refined presentation. Phonics has long been respected for their minimalistic style and technical precision, and Stereo is a great example of their approach.

The demo was created by the Phonics crew, with code by Krill, graphics by Deekay, and music by Drax. Their combined experience and long history in the C64 scene give Stereo its distinctive look and sound. The demo’s timing, effects, and overall flow reflect the group’s focus on clarity, rhythm, and well‑executed design rather than flashy overload.

This capture was recorded on real hardware using an 8580 R5 SID chip installed in a Commodore 64 Ultimate. The 8580 R5 is known for its clean filter response, stable envelopes, and crisp modern SID character, making it ideal for demos that rely on precise timing and clear sound design. Running the demo on the Commodore 64 Ultimate ensures cycle‑accurate playback, stable voltage, and hardware‑level authenticity, preserving the exact look and sound intended by the creators.

If you enjoy C64 demos, real SID recordings, or demoscene history, this is a faithful hardware capture of a classic Phonics production.
